Two things you thought you weren’t going to get: a manufacturing date and an SoC datasheet

I’ve got some bad and good news about manufacturing. The bad news is that it’s taking a little longer than we’d hoped, because the factory had some trouble sourcing a specific component. The quartz crystal package we had chosen when we thought we were manufacturing in the UK is readily available over here in Europe, and was the cheapest we could find; but it turns out that in China, that crystal package has been overtaken in price and size by a smaller, cheaper one, so the one we’d designed for has been a bit hard to find. The factory has sourced crystals now, so we’re all go. The good news is that this finally means we have a date for the first batch: the boards will be finished on February 20. Eben and I may be going to China to make sure that the boards can be brought up properly for that date if necessary. We’ll be airfreighting them to the UK immediately, so you should be able to buy them before the end of the month.

There’s another big piece of news today. We’ve been leaning (gently and charmingly) on Broadcom, who make BCM2835, the SoC at the heart of the Raspberry Pi, to produce an abbreviated datasheet describing the ARM peripherals in the chip. If you’re a casual user, this won’t be of much interest to you, but if you’re wanting to port your own operating system or just want to understand our Linux kernel sources, this is the document for you. You can download a PDF here. Huge thanks to Gert, JamesH, Gray and Dom for, once again, going above and beyond for us. We really appreciate it.

+1 definitely. I much prefer to know what’s happening.

Bloody Fantastic !
Stuff happens but hey there will be boards, it’s good to have patience :).

Avatar

Bloody Fantastic Indeed!!!

Avatar

Can’t wait for the release (although probably of the fourth or fifth batch if demand matches anything near interest shown here). Enjoy China!

Avatar

Good news. Glad that I’m busy with exams this month and I hope I can play with a Raspberry Pi after that :D

Avatar

Congratulations, that’s excellent news, and very impressive that we can get hold of some information about the SoC. Interesting about the oscillator, perhaps a bit of further cost cutting can be done in the future!

Avatar

Hooray, that is great news about the datasheet.

Avatar

A datasheet for a Broadcom chip? Did I accidentally load up the onion?? Is this the first time this has EVER happened? (Without an NDA.)

Avatar

Quite possibly.

Avatar

Nice one Liz, if this month goes as fast as last month then we’ll be laughing.

Avatar

are you kidding ? the past 2 weeks has been the longest weeks ever .. i kept refreshing raspberrypi.org every hour or so worrying that i might missed out. well at least now i can rest from refreshing page until the 20th …

Avatar

+1 :)

Avatar

Great news from the bakery! I hope many of us will be able to acquire a board from the first 10-thousand batch!

Also, it sounds like the “smaller, cheaper one” crystal from China was not implemented in your device, instead the cheapest European-available crystal was used, is that true? Was there any difference between the two or is it just different timing?

Avatar

The size difference, unfortunately. We’ll probably incorporate the smaller, cheaper one in revisions later on.

Avatar

What is that crystal problem about exactly? I don’t really get what that thing is supposed to do on the board…
Maybe someone can explain to me? ^^

Avatar

Quartz crystals provide a clock signal that regulates all the other components. They utilise the mechanical resonance of the crystal to produce a stable electrical oscillator. http://en.wikipedia.org/wiki/Crystal_oscillator

Digital circuits such as microprocessors have delays in processing and moving data about and a clock is required to regulate the system so that data is not read before it is available. Different parts move at different speeds and the master clock is divided down to appropriate rates for each component of the system.

Avatar

Divided down, or scaled up in modern systems.
I’m guessing there is a 25 MHz crystal on the raspberry pi, and it is scaled up by a factor of 20 or 28 to get the main
system clock.

Avatar

The second part of your explanation is not entirely correct in that clock is not just used for timing the data access. It is the heartbeat of the whole system that makes things move. The CPU executes instructions based on the clock cycles.

Avatar

So based on your text, was the system planned to be manufactured in Britain along with the original crystal, or China?

Avatar

British manufacture was an original aim. There are various blog and forum posts about it.

Avatar

Good! Hope to get one of them in 2 weeks!

Avatar

Two weeks is too early. The boards will be finished on February 20. And then shipped to UK. And then you can order. And then wait for shipment. 3-4 weeks is more probable…

Avatar

Woohoo, time to set a calendar reminder for the release date :)
Congratulations on getting these things going, I am sooo looking forward to the final release :)

Avatar

Hey, I’ll take it! I can wait a couple more weeks. But yes I’d hope you guys are going to China to check the boards out before they get 10,000 of them built…

Avatar

One day later and I could call that a proper birthday present!
…but, don’t delay it on my account, okay? :-D

Avatar

14 Days and counting

Avatar

Thank you for the update. Now we’ve got a clearer time frame I can stop checking the site every few hours!

Avatar

“Eben and I may be going to China to make sure that the boards can be brought up properly for that date if necessary.”

there are much simpler ways to get a decent chinese’s takeaway

Avatar

will the first batch be a mix of A and B models ?

Avatar

The first batch is only model Bs.

Avatar

o yes!

Avatar

“There are 54 general-purpose I/O”, “All GPIO pins have at
least two alternative functions within BCM” -> IMPRESSIVE, if in a future revision you can manage to bring out half of those pins to headers i can see a lot of “armduinos” based on .net becoming completely obsolete and for the same (or approximate) price, we can get not only the amazing io but also a huge amount of ram, disk, USB and network.
PS: I mentioned huge ram and disk and I am not talking of upgrades to theses items, by micro-controller standards even the 128MB ram and 128MB storage are absolutely huge, can’t wait to see what new devices will be built based on this, heck the famous arduino that has been making wonders with the community has “only” 32 KB + 1KB storage, 2 KB ram and 16MHz

Avatar

With a micro controller sometimes you end up using it to control a piece of kit thats more powerful than the arduino. From what I’ve seen a raspberry pi with ethernet (model b) is a lot cheaper than an arduino with ethernet.

Avatar

Plus unlike the ardunio the Pi runs a full version of linux so you can write your web interface using APACHE/PHP rather than being forced to do it in whatever variant of C the microcontroller uses.

If I watend a board to networkize something and I didn’t need much GPIO i’d probablly go with a Pi. If I did need lots of GPIO it would probablly be a tossup between Pi+PIC or beaglebone.

Avatar

“whatever variant of C” they actually support regular C99 and C++03 as they just use GCC.

Avatar

Part of the brilliance of the Arduino is its simplicity. It’s a different piece of kit to the Raspberry Pi, and will co-exist happily. If you’re trying to get children to build their own burglar alarms or digital alarm clocks or whatever, you don’t really want the complexity something like linux getting in the way.

Also, once your programme is on the MegaAT you just connect power and it runs. It’s like a glimpse behind the curtain of modern electronic hardware.

Avatar

I’ve had such a thing happen to me in the past, interestingly with crystals as well. There’s always some other problem to deal with…..

Congratulations on getting as far as you have.

I’ve decided I’m not going to try and pile in and get one of the first batch. I can’t claim to know anything about Linux (I’m hoping the RPi will teach me!) so think it makes sense to wait for the community to get hold of them first and come up with ideas and guidance.

Avatar

Given the (very) broad timescale outline that Eben mentioned in the mid-Jan interview, I imagined that the lack of Pi around now was because of an unforseen manufacturing hiccup. I’m glad to hear that its been sorted and that the production lines are rolling!

Its wonderful news and thanks for sharing it with us.

Avatar

The fact that we have a date is great news :)

Thanks for keeping us informed, can’t wait to place my order!!!!!!

Avatar

Awesome news. Does this mean it will be available in the store for this site around then?

Avatar

This is great news, i need to pre-order one right now!
Can’t wait t’ill march, when it’s shining next to my TV.

Avatar

This is fantastic info! Well Done!!

Out of interest I was searching for GPU info in the datasheet which, as expected, is limited. I was intrigued by the statement in the overview which says “There are a number of peripherals which are intended to be controlled by the GPU. These are omitted from this datasheet.” … hmm, does that mean another datasheet regarding GPU control might also be available in the future?

Avatar

Probably not. It’s controlled through closed-source binary objects, so you wouldn’t be able to use a datasheet. (This is also the case with all other mobile SoC platforms – OMAP, Tegra etc. etc.)

Avatar

I have been reading about efforts to reverse engineer a GPU family called Mali that are embedded in the ARM. Is the Rpi GPU a so-called “Mali” unit? Would the Lima Project efforts to reverse engineer it be relevant to the Rpi user base?

http://www.phoronix.com/scan.php?page=article&item=arm_mali_reverse&num=1

Avatar

An even more recent article on the Lima Project to reverse engineer ARM GPUs :

http://www.phoronix.com/scan.php?page=news_item&px=MTA0OTQ

Avatar

Nope, it’s Broadcom’s own VideoCore IV.

By most people’s reckoning it is by far the most powerful GPU currently available for embedded ARM.

Avatar

Typo on page 38 (harware instead of hardware).

But more importantly, can we get a quick list of exactly which pins are brought out to the PI’s GPIO header?

Avatar

I’ll see if I can get Eben to do you a list tomorrow. (Afraid I can’t fix typos in the PDF – I can’t imagine that anyone’s going to be confused about what “harware” means, though!)

Avatar

Yeah, typo isn’t really important; just something I noticed and had to be OCD about. :)

Can guess some of the pins from the known GPIO pin-out, but it’s easier with a definitive list.

Avatar

Another minor error in case it momentarily confuses anyone else:
On page 104, in the legend for Table 6-31 the UART 1 pins are labelled TXD0, RXD0, CTS0, RTS0 instead of TXD1, RXD1 etc.

Avatar

if you look closely to the table 6-31 the first part shows both txd0 etc. and TXD1 etc

btw, computers start counting at 0

Avatar

TXD0 etc is for UART 0
TXD1 etc should be for UART 1

Mistake is only in the legend.

Avatar

Perhaps a few people could collect the typos they find and put them all together in one place & make a sticky post on the forum, for future reference.

Avatar

I’ve started a wiki page:
http://elinux.org/BCM2835_datasheet_errata#p38_typo

Looks like general gpio header P1 contains:
0,1,4,
7,8,9,10,11,
14,15,
17,18,21,22,23,24,25,

Avatar

I suspect that Pins GPIO22-27 have ALT3 to be the SD interface. Wouldn’t those be connected to the SD card?

Avatar

GPIO22-27 is SD1_x which to me sort of implies a second SD interface (where’s SD0_x).

Avatar

SD0_x is probably a dedicated SD card interface (not multiplexed with GPIO) – so not shown in that table.

Avatar

Thank you, good to hear the latest news on the harware.

Woot!!! my bday is on the 21st :D hopfully ill be able to get one out of the first batch.

Avatar

Mine is on the 22nd :D i think ill have more chance of getting one on my bday ;)

Avatar

I’m also on the 22nd of Feb and want this to be winging it’s sweet way to my door.

Avatar

Tremendous work :-) The Raspberry Pi project is going to be epic!

Avatar

205 pages is an “abbreviated” data sheet. I’ve must have been away from that level of stuff for too long. The Z-80 processor, which is the first one I worked with has a data sheet 10 pages.

Avatar

This is a lot more than a processor, it is a complete system. And the processor is a bit more sophisticated than an 8 bit Z80. It scares me that I still remember the hex for some z80 instructions from writing assembly on paper, translating to machine code and putting them into data statements to poke into memory as a high school student nearly 30 years ago.

Avatar

I was doing that 25 years ago – loading Z80 assembler into memory using a basic bootstrap on a CP/M machine.

I sure wished I knew how modern operating systems worked now as well as I knew those things then :(

Avatar

I know the feeling: just finished a Beagleboard project. 3500+ pages for the OMAP reference manual. Then you need the ARM manuals for peripherals like the MMU…

Avatar

Datasheets (or specifications) with over 500 pages and even more than 1000 pages are relatively common.

Avatar

Yup, a typical Microchip MCU’s datasheet is over 600 pages nowadays; heck, the Bluetooth 4.0 specification alone is over 2000 pages long. That’s what I was talking about when I said specs of hundreds or thousands of pages are nothing special and should not be quoted as a horrible thing to read; they are just business-as-usual.

Anyway, in most chip specs the bulk is taken by the description of peripherals, and in that light the “200 pages abbreviated” datasheet is nothing surprising (and most welcome, thanks guys!), nor is the fact that the Z80’s spec was rather lighter, considering it had exactly zero peripherals on-board (and yeah, well, architectures had a lot less bells and whistles back then).

Oh, and one more thing – NEVER confuse a “brief” with an actual specification / datasheet. Those are the ones that tend to be 2-10 pages long, even if there seems to be a tendency these days to call them a “spec”, and the actual spec / datasheet a “user’s manual”.

Avatar

You’re not just teasing us are you??? Is the 20th Feb the date that the boards actually leave the facility in China fully QA’d and en-route to the airport???

With only 9 days before the end of the Month, will you *really* get them through importatin and into the distribution channel before February ebbs away…

I think you’re holding out for the 14th of March. ;-)

Seriously, although we’d have loved to have had our hands on an RP weeks ago at least we now know the wait is nearly over! KUTGW!

Avatar

To be honest, I think having it release on 14th March would be a really nice touch. I know I’m as eager as the rest of you got get my hands on one, but 14th March is an awesome release date.

Avatar

How will you ship the boards? Will Standard Royal Mail be the only shipment method available? Will be UPS or something quicker to ship it? (more expensive, of course)

Avatar

You can’t drop ship the boards direct from China can you? Seems a crazy waste to send them to customers in the Asia/Pacific via the UK.

Avatar

There’s actually a little more to the logistics than I’m able to tell you about at the moment, because we’re still in negotiations. You’re right, we’re not being quite as blunt-instrument about it as you think.

Avatar

You need to employ Father Christmas and his elves. They must be at a loose end at the moment.

Avatar

The Easter Bunny would be a better fit to my expectations for delivery date than Father Christmas. I might be able to convince/help a child to lose a tooth if the Tooth Fairy can be roped in to the logistics.

Avatar

Actually, Father Christmas works the rest of the year at my work. I could ask him if he’d help.

You think I’m joking….but I’m really not.

Looks to be 65 years old, but he’s looked that way for as long as anyone’s known him. Long white beard. Big belly. Happy smily face. ALWAYS takes two weeks holiday in the lead up to Christmas. Always comes back “from Germany” tired….and does not confirm or deny anyone’s comments…

Avatar

There is a Santa-lookalike who works in tech in Cambridge (I’ve seen him at a few business open evenings). He always wears red from head to toe. I am not sure whether he’s just a monochrome gnome, or the actual Father Christmas.

Avatar

The head of the workshop at the engineering department in Cambridge is a kindly grey-haired gent called Mr Christmas. The workshop lights always seem to be on long after everyone has gone home, but then the windows are probably above elf height…

Avatar

Fantastic to have a date, I have been reloading the news page multiple times a day for some time now :) Hope I can get one :)

Avatar

Will the board be available for local shipping abroad like in the US? or it will be shipped from UK? and how much the shipping fees will be?

Avatar

And will this available to Russia at the sales start?

Avatar

I’m 140% sure that it will be available to Russia too :-)

Two weeks! two weeksssss!!! :P

Woo wee!!!!
hopefully i’ll get one for Feb 27th (My birthday!!!) ^_^
(Starts scrimping and saving for bits to make an uber-pi setup )

Avatar

So, when the manufacturing is complete on the 20th, then we can buy them?
I guess you have to make sure that the shipping is negotiated. When you do start selling them, can you post the time and day the day before? These things will sell out in 30 minutes, provided the server doesn’t go down.
Hopefully, could you sell at about 12:15 London Time?
That, being 6:15 in Central US, is a time those not at work already here can get up for. And 12:15 is lunchtime,so can’t you have your pi then? :D Or maybe at 3 or 4 London. (9-10pm)

Avatar

I’m assuming they arrive on China on the 19th,
Recover from the flight and get to the Factory on the 20th
See everything is OK for shipping
it gets to the airfreight terminal late on the 21st
gets loaded on a pane and departs mid 22nd
Arrives UK late 23rd.
Customs drags their feet till the afternoon of the 24th (they need their tea breaks!!)
Gets put on delivery vehicle very late 24th
Arrives at R-Pi HQ on the 25th
Shop goes live 00:01am on the 26th
Then crashes 00:03am on the 26th (DDOS due to numbers of people trying to get one.) ^_~
Site gets back on it’s feet on the 27th when I will be able to but one…

Avatar

You forgot the sightseeing trip to The Great Wall, The Terracotta Warriors, etc. If you going to China you might as well get a bit of fun out of it.

Avatar

well they have got between the 21st and the 24th for sightseeing ^_^ lol

Avatar

You forgot, customs hold the package on suspicion of explosives, lol.

Avatar

hope it won’t come to that >_<

Or they get seized and destroyed by the H.M. customs office as they will misread the shipping label: “Raspberry Pies” – a.k.a. food – from China.

Hope that doesn’t happen.

Avatar

I hope the site doesn’t crash… I still would love a 12 or 24 hour approx notice and then a countdown to release on the header would be nice when they’re ready to be bought. (6pm on sat 25 for USA). I know that if i have no notice I won’t be able to get one, even with 10000. just how many are going to be ordered right away, do you think?

Avatar

What time on the 20th will the Pi be released for ordering in the US?

Avatar

Please read the post again. The 20th is NOT the date sales will start, but the date the first Raspberry Pis are finished at the factory. Before we sell them we have to test and freight them.

Avatar

Be sure and thank whoever made the decision at Broadcom to allow the limited release. This document will be very useful for me, and I’m sure for innumerable others.

Thank you.

Avatar

Very nice, thanks for the PDF. Still hoping Eben will be able to make the 24 GFlops of GPU performance available for computation as he said he hoped he would be able to do!

Me too! I not going to need 1080p, 3D acceleration or even a direct display out. But I would love to have a bit more math power to play with!

[quote]but if you’re wanting to port your own operating system or just want to understand our Linux kernel sources, this is the document for you[/quote]

Usually much of this stuff would be set up by the BIOS, but it sounds like you are saying the GPU blob which gets the kernel into memory doesn’t set up any of this, so the kernel needs to do a fair bit? Doesn’t that mean a lot of hacking of the kernel, which takes it away from mainstream? Hmm – if so wonder if there is a scope for a second stage bootloader to set up the hardware, before passing across to a plain vanilla kernel?

Avatar

I think the binary GPU binary will get the HW to a fairly stable configuration (i.e play the role of BIOS). They mention the kernel so you can figure out exactly why they are reading or writing to address 0x7EXXXXXX (in the kernel srcs there will likely be some nemonic for the address but still having all the bits documented is _really_ great and Broadcom deserves a lot of credit for making the info public).

Avatar

Yes, some more thought, probably just do kernel bits for the IO stuff that needs to be timely (e.g. won’t be RTOS, but you want more timely response than a user space ap).

If so suggest just coding things up as modules, and making the kernel bit as thin as possible (e.g. just get data on/off, do some buffering, and set up registers), then have use space do any processing of input that needs to be done.

Do try to get the kernel modules accepted in the linux mainstream.

Do you have any idea how long a second, and even third batch will take to be manufactured? I wouldn’t be surprised if all 10,000 sell out in a couple of hours :-)

I did wonder too if you had any idea how many you will be manufacturing in future batches, or is this based on how well the first batch sell?

Great news anyway, I’m sure it’ll be worth the wait. :-)

Excellent news. I hope you have enough Pi’s to fill demand because I’m sure that a lot of hobbyists, such as myself, will be looking to nab one for our own projects :) .

Are the orders still being limited to one per household?
I have a roommate that is hopeing to order one, and i want one too, is it one per address or one per person?

Thank you.

Also its unbelievable the entire raspberry pi project. the dedication, the community support, the perseverance, just the entirety. i dont know how to express my admiration.

[…] The latest update from Raspberry Pi is that they will be receiving manufatured devices from the Chinese manufacturer on 20th February. This is great news for the everyone interested in these groundbreaking devices. In my School of Computer Science we are looking forward to using them in many ways with undergraduate students, and also with local schools. Their novelty aside, the sheer affordability of the devices and their relevance to the ongoing computer science education debate is a compelling story which is unfolding. I hope we see a new generation of young computer enthusiasts start to emerge and follow in the footsteps of those who went before them in the 1970′s and 80′s. Their achievements paved the way for the modern day computer games industry, the social media revolution and pervasive mobile device proliferation we see today.

Thank you for the datasheet (and for the date). But we need the board schematics in order to get a complete technical information.

It is near impossible to begin same hardware projects without it.

Do you know when will you release it? Before shipping?

Avatar

Damn, putting that pesky business thing in front of beautiful symmetry. You guys should be shipping on March 14th (3/14). :)

Avatar

31st April and I don’t want to wait that long.. ;)

Fantastic news. Does that mean that the boards can be made cheaper in the future with the new crystal? In any case, can’t wait to get my hands on one. Already have plans for it!

Well done guys.

You can try subscribing to the mailing list, but if the mails are sent in the order of subscription, you will most probably get the announcement after all 10000 are sold.

Avatar

Great news!
Maybe you’ve thought about it already, but why not ship world wide from China directly instead of going through the UK first?
Most items I order from ebay and are shipped via China Post office are ‘free shipping’ so I assume the shipping cost is quite cheap compared to China->UK->World.

Still 10.000 units for the first batch ?

Just got back from China yesterday and let me tell you that it’s bloody cold there at the moment. -27 celcius in Harbin and not that much warmer in Beijing and Shanghai. Remember to pack your down jack, beanie and gloves.

Update appreciated, especially the pdf :-)

No DSI/CSI information in the pdf :((((((

They are ports on the GPU, not the Arm.

Avatar

Why don’t you guys just give in and take a few pre-orders, let’s say 2-3000, and then keep the factory going for another 5-10k with the money? By the time the second batch is done you will have sold the full 10k and will know more about demand and can put in another possibly larger order. Caution to the wind, now! ;-)

Thank you so much for the BCM2835 ARM Peripherals datasheet. Please thank Broadcom for creating this and allowing you to release it.

Avatar

It strikes me that with this amount of interest, it would make some sense to allow “registration of interest” – you can’t order a Pi unless you have pre-registered. (note I don’t say pre-order here). Doing this might reduce the load on the release day. Pre-registees (is there such a word?) could be invited to buy, perhaps as some sort of lottery.

Avatar

You’re not the first person to suggest that. I’ve explained elsewhere why we’re not doing it. In short, there’s absolutely no upside for the Foundation in doing that; on the contrary, it’d create a ton of administrative work which we really don’t need at the moment! I know everybody here would like to be assured of getting one from the first batch, but I’m afraid we’re not going to make a load of extra work for ourselves at a time when we’re already stretched.

Avatar

Here’s a possible head-start sop to the faithful that wouldn’t require any additional administrative overhead. Set up a new, seperate Official Rpi For Sale twitter account and let people register for it, then guarantee that the initial announcement of the sales site going live will be made solely via this twitter feed at the instant the sales site goes live. Even better, state a particular Zulu time of day that the sales site will go live / twitter notice will go out. Then if that time of day passes and no tweet, everybody gets to relax for another 24 soild hours.

Avatar

I completely understand the reasons for trying to lessen the Foundation’s overhead – and I’m also sensible enough to realise that there is very little chance of obtaining one of the first batch of Bs. It just annoys me that a large percentage of the first batch will go to speculators who’ll immediately stick their shiny new Pis up on Ebay.

Avatar

If manufacturing is finished on the 20th,, will it be packaged and ready to go same day? You may want your forwarder to start booking space with the airline for the 23rd or so (give some buffer room) and get the export licensing in place – if you don’t start the process soon, you could lose out on some days if you really do want these delivered in the UK by end of month.

The actual moving of the freight isn’t the hard part, its all the preparation which alot of people forget about.

I attempted to skim through the PDF, of course couldn’t understand 99% of it.

The one thing I did get from it is the minimum amount of RAM the GPU will use is 32MB and that is not enough memory to buffer a 1080p30 video. Doesn’t say how much would be needed though.
Just thought that would be of interest to some people.

They won’t be going on sale on the 20th – if you read the post again, you’ll see that’s when the manufacturer is finishing them, not when we hand them off to the logistics team. So you don’t have to spend the 20th pumping away at F5.

Avatar

ok, so, i know it’s gonna be quite difficult for everyone to get a RPi from the first batch because everyone and all their friends want one, but, would you guys recommend getting one?? i mean, how different will they be from the next revision?? if it’s only the crystal size (not the frequency or anything else) i dont see a problem, but if you’re going to keep changing some other things, it might affect some compatibility between revisions… right?? i mean, im a geek, but not thaaat much to make my own OS port
how long would it take to have the 2nd batch ready for shipping??

also, would it be ok with you guys if i use the RPi for an “industrial solution”, i mean, not a mass production thing, but install maybe 100 within a 2 years lapse, or so… (if everything goes better than expected), of course not from the 1st batch… i want only one from the 1st batch for myself, to play and learn!!

Avatar

There won’t be any electronic difference at all. Anything called a Model B will exhibit exactly the same behaviour as anything else called a Model B – if we do end up using the smaller crystal, it’s just like making the same cake recipe again, only using a differently branded pack of butter.

Avatar

nice gastronomic comparison!! i guess you miss blogging about food and recipes, right?? hehe

that’s ok then, as long as you dont change many things!! thanks!!

and what about using it as an “industrial solution”?? using RPi to work along with a PLC, would that be ok with you, guys?? i’m thinking on about 100 in 2 years… tops!

Absolutely fine. We actually talk about this a fair bit in the forums – if you’d like to learn more about our philosophy on entrepreneurship, I think you’ll find the forums very interesting.

SUPER!!! A huge “Thank You” to the Rasπ team for their hard work and to the kind folks at Broadcom for sharing!

One other thing. I’ve read somewhere that for instance the SPI driver won’t be p
orted / provided by the foundation. They are “hoping the community will take car
e of that”. Well, with this datasheet, that’s a whole lot more likely to be easy
to do….

This belongs as a reply to a posting on page two. However, when I hit reply there, I get the “password incorrect” response (hit back and enter the password, which if executed would zap the comment I typed).

My normal “workflow” (workaround) that seems to work is to hit “reload” and then immediately hit the reply and copy-paste my old comment that I’ve had to save in an editor window back into the comment box.

However this workaround doesn’t work on page two. I don’t get zapped back to the place where I was commenting. Is everybody using Internet Explorer or something like that? I seem to be the only one who finds this commenting system so annoying.

Maybe a silly question but – can’t you ship the boards to the customers directly from china?
When i buy something from ebay, shipping costs are usually a lot cheaper if i buy from china or honkong, than if i buy from UK. I can buy china stuff for 1$, including shipping costs. So to me it would make more sense to sell at least a part of them directly from china. Shipping might be slower, but also cheaper.

[…] $35 Raspberry Pi computer to launch later this month Posted by ashton on February 7th, 2012 The low-cost Raspberry Pi Linux computer is set to become available for purchase later this month for $ 35. The firm behind the budget computer announced on Monday that the first batch of boards will enter manufacturing on February 20th and will be available at the end of the month. The single-board computer is equipped with a 700MHz processor, 256MB of RAM, SD card support and both HDMI and RCA outputs. Despite the low cost and small size — which is roughly equal to a credit card — the Raspberry Pi computer is powerful enough to run games such as Quake III Arena and power 1080p video, however the company intends for the device to be used in schools to teach the basics of computer science. A second Raspberry Pi model with 128MB of RAM will be released for $ 25 at a later date. Read […]

What if you talked to the manufacturer and set up a system where they could ship orders out directly for you. I bet a lot of customers are not in UK .. so might save some money along the way there. It might be less tax and less shipping time if they could be shipped straight out of china.

Avatar

Every (other) time I get something sent from China I need to go to the post office to pay 25p duty a few pounds VAT and a nice £10 fee for the trouble (in Sweden). So for a lot of people it will be very inefficient to have it shipped directly from China and you wouldn’t know the total cost until you know if you are lucky in customs.

Schematics are already dancing in my head as I pour over these notes. Could you clarify what has to be a typo? For the GPLEVn registers on page 96, you say in two places “0=GPIO pin n is high”. Shouldn’t these 0s be 1s?

I have no idea. I did not design the GPIO pins. Nobody has complained about that yet. Still I will check. For that I will have to delve into the Verilog code and see what the correct answer is.

Avatar

I posted this because the “expected date” has been set back 3 times now.

I will wait for the allwinner a10, it will probably be released before the pi andway and if not, I have waited this long already, a little longer won’t hurt. plus it is half the price of the pi and well over double the speed.

Avatar

I was under the impression that the a10 CPU based system you refer to has:
1) Not been built yet there’s only a $2,000 dev kit
2) Has no expected date
3) Its quoted price is based on a 100,000 qty purchase as opposed to the Raspberry Pi’s 10,000 qty.
4) There is no publicly released datasheet
5) Uses closed source libraries for its GPU
6) Proposed form factor would be larger than the raspberry pi
7) Uses more electricity than the raspberry pi

Avatar

I’m afraid Philip is going to be somewhat disappointed with the a10 device. I doubt we will see any of those for at least 6 months, and when they come out I expect them to be not as good as the advertising, and more expensive. Still, he’ll be able to watch all the Raspberry People playing with theirs, so at least will have something to watch.

I concur that the Raspberry PI will not come with an SD-Card, so without any software at all?

Is there a place where one can download some “demo image”, (software image) so the Raspberry π will boot to something, if even if it will just display a logo, so we can see if our setup works.

Obviously we will need information on what and where to place on our SD-Cards too, and how to format it, (probably some kind of FAT formatting).

It would be very frustrating and disheartening for many people who receive their Raspberry π to discover there is nothing they can do with it at the time they receive it.

Also, what will exactly be included with the board, for example does it come with a power supply? From what I have seen the Raspberry π uses a non standard power connector.

Not that anyone will get to the point of reading this comment, but…

The reason for only putting out 10,000 units to start: shake out the bugs in the system design/MFR processes. If after 10,000 units produced, >~99% work properly (per MFR price projected), the go-ahead is given (otherwise a revision made).

The savings on the oscillation crystal is probably too small to reach the consumer. Typical pricing for 1000 SMT components (resistors/caps) is under $40-$50 US (from my memory, probably faulty). A discount in that range would be negligible for pricing purposes (at a penny each per $10 drop over QTY). You most likely will see savings at a production cost of two-thirds to half (at which point, there is no reason to own any Intel/AMD CPU).

Anywho, can anyone say “Cheap Beowulf Cluster”? Now to wait for TbE…

Very good news. Looking forward to being able to buy one. As a retired teacher of IT and computing, I am glad to have a bit more time to play with the RPi. It’s also great to see the Govnerment waking up to the need for pupils to learn about computing in schools. Maybe we’ll get back to the fun we had programming the BBC Micro in 6502 assembler. With a former pupil I helped to develop a Network Filing System which we called ENFS and which Acorn allowed us to market as an add on to their version. Basically it read their ROM code and patched to add a data buffering sysetm, which dramatically increased the throughput when file handling over the network. You really felt you were at the forefront in those days. Who know what avenues the RPi will open up to the pupils of today.

Given the detail provided by the SoC datasheet, I am officially starting PCB layout of my add-on board project as of today. (See what you’ve started?) I understand from the FAQ that the Rpi is exactly 85.60 by 53.98 mm. What is the exact X,Y displacement of the center of the GPIO hole closest to the corner of the board, relative to the corner of the board? Ditto for any mounting holes drilled into the board, along with their official diameters? This is going to be a basic set of numbers for anybody embarking on an expansion board project, perhaps the answers are worthy of being an addition to your FAQ?

In addition to my queries above, I would also appreciate some clarification on some confusing and contradictory board size information scattered around the site. In the FAQ it is stated that the Rpi board is 85.60 by 53.98 millimeters in size, which is the official standard ISO / IEC dimensions for an ID-1 card like a credit card. Yet in the forum post “Beta Boards Mechanical Data”, Gert says he took calipers to the beta board and measured its size as 85.00 by 56.00 millimeters, and he has published his direct measurements at scribd that case builders are apparently using. So is the Rpi officially the ISO size stated in the FAQ or some other size (85 x 56 mm)?

I went back to the Nov 14 posting where you first showed the Rpi Gerber plot, embiggened it, and threw it into Windows Paint as a BMP. That Gerber BMP file is 827 by 544 pixels (aspect ratio of 1.52022) and so is a lot closer to 85 x 56 mm (aspect ratio of 1.51786) than 85.6 x 53.98 (aspect ratio of 1.58577). There is some distortion in the BMP with 26 pixels horizontal and 25 pixels vertical between the 0.1 inch centers of the GPIO bus used for scale so neither version is probably true but the 25 is probably closer than the 26 because it comes out much closer to Gert’s observed 85 x 56 and neither comes anywhere near the ISO/IEC 7810 standard that was your initial target.
Bottom line your board is apparently 0.6 mm less in one direction and a tad over 2 mm longer in another than you had planned, for a final size of 103% of your target. THAT IS AMAZING FOR A PROJECT LIKE THIS. I work on a team getting ready for maiden flight of a military airship and we would have been THRILLED to hit only 3% weight growth. TOTAL CONGRATS!!!

On the datasheet, Thank you. Now I can start porting my simple OS. :) I have already ported it to the Risc PC (using RPCEmu), and the Commodore 64, now for its intended destination, Thank you.

0) THANK YOU so much for the datasheet, it’s exactly what so many trolls wanted (myself included), so it’s a real treat to have access to such important information. If the worst of the complaints now are spelling/grammar issues, that’s definitely a win!
1) as someone who’s been onboard for a while (though still a johnny-come-lately!), I’d like to add my formal concern about speculators or “investors” (none of whom are actually either) obtaining “Batch zero” boards, while many folks who’ve been extremely dedicated and helpful in the forums may (nay, will) miss out.

No, it’s not the end of the world as we know it, but it WILL generate ill-will, believe me. Without adding to your headache/workload, perhaps a formal request to those induhviduals not to behave unfairly or antithetically may help to minimise this kind of unwanted behaviour? Tied in with serialised boards, that would be an effective deterrent to all but the most bloody-minded creeps; failing serialisation (and the attendant overheads), a wall of shame/banning IP addresses or email addresses of users positively identified as slimy, money-grubbing, little baby kitten-hating speculators might be the go!

I’m sure I won’t be quick enough for a batch zero board, but in all seriousness I would hate to see genuine RPi buffs shafted by greedy manipulators, even if it’s only a few! Perhaps a barter or second-hand system might help ensure those who really want to use the RPi’s get a chance at them? I’m not sure how (or even if!) that would work, but my Tullamore Dew is telling me this could be an option… (yes, it’s beer o’clock at last!) :)
2) I hope your trip to the Mysterious Orient is a bit more fun than your honeymoon!
3) thanks again for the unexpected dock, and the unflagging support & patience. The pain will end soon….!

Any individual can only buy one anyway, so we hope that will rein back most of the speculators. As will the fact the next batch will be out son after.

The plan is to sell boards on E-bay for the standard price at irregular, unexpected times. This should put the brakes on anybody who gets one from the first batch and want to sell theirs on E-bay.

This is great news! A friend just sent me the link and I’m definitely going to buy one! Sooner rather than later! How do we get to know the order page?

Good news! It’s an interesting project and I look forward to test one of these.

I fear that it could not produce enough product to provide sufficient quantity in the market

We fully expect the frist batch to sell out pretty fast. Then we make a second batch, then a third. Time between batches should be pretty short.

I’m looking to write an OS from scratch, do the base in C, bootloader, memory handler etc.. A proper unix-from-scratch with no ties, what would I need to become a developer? I’m well versed in current PIC usage, memory stuctures etc, GDI type libraries etc, have 30 years of to-the-hardware coding learning a lot fromt the ZX81/spectrums etc, Electron/BBCb, and the Atari ST… Now I just use windows and feel really abstracted, so would like to just start from scratch….

Is there a devkit package I’d use best?
Also, there is somewhere in the UK that can program up to 1200 cores an hour, is this of interest?

Your way of explaining everything in this article is genuinely good, every one be able to effortlessly know it, Thanks a lot.

What?!?!?! Never seen a broadcom sheet available to public, damn i love broadcom for doing this.

Broadcom, thank you very much for doing this.

Avatar

Pleasure!

Avatar

That sheet is a step forwards. That will sheet will at least give a starting block for freertos and other different open source kernels to stand a chance of working.

Yes its very simple to forget FLOSS OS’s exist that are not Linux. When wanting people to learn about OS’s seeing more than one is a good thing.

I guess there is no hope of getting the binary graphics libraries ported if any of the other FLOSS OS’s get enough interest?
