I want to write an OS for the Lego NXT 2.0, but I can not find information about the architecture of this system. Does anyone have any examples? Or any other useful information on the topic?
A:
I'd guess the first step would be to establish the hardware your OS will run on. What is the CPU and supporting chips, etc. How much memory, storage, what form of IO does it have etc. If you cannot get that from Lego themselves, I'd guess you will have to tear down a unit to get chip IDs and numbers and reverse engineer from there.
How difficult this is? perhaps someone with embedded hardware or Linux driver experience might be able to guess at.
