I see. They have published the support code at

It is quite similar to the code for other computers such as the Qnap
TS-219, but it is split between three file. I am not at all a kernel
hacker but it looks like it is about:
• flash modules, LED, buzzer and switches that are plugged to GPIO pins;
• Ethernet (two NICs);
• timer.

So indeed, it should not be very usable without this code. As I said it
is already written and published, but I am not sure it is yet in a state
eligible for mainstream inclusion. However, not being skilled enough in
C and kernel programming, I do not think I would not be able to do the
required refactoring. I am quite new to the ARM world and I did no
tthink there was so much small variations within a given platform
(Kirkwood, I mean, not ARM as a whole).

My point is not to get a custom Debian running on a given B3, as it is
in fact already the case for all the B3 sold, as they come with a custom
Debian, but rather to make them natively supported by pure Debian.

So I am not so sure I will be able to do that port, and I should
certainly not ask Excito to send me a free B3 for porting Debian to it
if I cannot actually do it.
