I have an N810 and sincerely the device has long been abandoned by me. Since one of my hobbies is electronics, I like to do something with the device from 0. That is, develop from 0 an "operating system" I have been reading enough of the OMAP and how to generate the boot loader for ARM. I would need to know a little of the electronic architecture of the N810.
Start by analysing open bits from previous incarnations of maemo. Building OS from scratch is a few years deal for a big team of talented programmers with cooperation from designers etc. Not really a one-person effort, but good luck
