Hi!
I was wondering how were you able to convince Broadcom to give you the datasheet for the SoC? I tried to obtain a datasheet from them for a different chip for a similar project but they refused.
Regards,
David

Eben, the Foundation founder, Gert who designed the Gertboard, Dom and myself all work for Broadcom.
However, Eben is the one with the influence! He's also managed to get a decent discount on the chip (which would normally be reserved for very large purchases), and charitable status helps!
Note that the datasheet does not cover the GPU, which, if you were building your own product you would probably need. That's where NDA's and contracts are required and big sales numbers talk.

The data sheet is an combination of four internal documents. It was completely overhauled by me in my spare time and written specific for the Raspberry-Pi foundation. It only describes parts of the design which Broadcom are willing to release based on the fact that they are not seen as IP critical to the companies core competence.

I hope I can reward them somehow for this.

you can, by buying lots of devices [not from the first lot though]

Depends how you look at it.
It's a broadcom SoC, but yes it doesn't has anything to do with RPi.
I newer said it did

Broadcom has offices all over the world, lots of different departments. The part that did the SoC on the Pi (of which the people who post here are all part of) won't even have heard of this device! That's the way to look at it.

Gert,
A sincere thank you for making what specs are available for the BCM2835 public.
Am I wrong in assuming that no more are forthcoming?
Chip manufacturers usually fall all over themselves to make data sheets available.
It's very strange to have to plead for data sheets...
OK, here goes - "Please, sir, I want some more."
