I'm interested in processor architecture, and assembly programming, but I can't seem to find any documentation, or even the datasheet on the CPU of the Pi 2 (BCM2836). The document I'm looking for should describe all the registers, instructions, architecture/pipelines etc of the CPU

  • The instruction set is ARMv7-A. Looks like you have to be an "ARM customer" to get the manual though. >_< – goldilocks Feb 24 '15 at 18:56

    Registration is free, but still a nuisance :\ – Alex Feb 25 '15 at 0:09

I'm not surprised you couldn't find any information.

The BCM2836 is a SoC not a CPU. As far as you are concerned the BCM2836 is identical to the BCM2835 except for the different ARM CPU.

The main user CPU used on the Pi 2 is an ARM Cortex A7 with four cores.

If you search for BCM2835 and the ARM CPU you'll find all the information you could need.

  • Aah, I saw that very briefly one time, and wondered about it. When I worked with ICs at school, I always look up the datasheets by the exact number, just 'cause there's usually some minute variations between different chips. Thanks! – Alex Feb 24 '15 at 23:09

The GPIO between Pi and Pi2 are not on the same addres. This link will be help you.

    Welcome to Raspberry Pi! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Ghanima Jun 7 '15 at 15:04
