I wouldn't put it like that. IMO your hardware is not the best choice
for you because it is missing a proper boot ROM (256 kB flash would
be just perfect) to allow you using a decent boot loader without
jumping in loops.

Linux kernel how much memory you have, and pass all the other bot
arguments to it? And how will you get LInux into the DoC in the first
It's software, so all things are possible. But not all things are
