You're of course welcome to join the Linux/MIPS team!
Current status of the port is that 1.2.11 kernels run user code
on three platforms and halfway work on two other platforms. 
The 1.3. kernel has been tested on a single platform yet, but
others will follow soon.
>From a technical point of view, 1.2.x is rather a hack, but,
however, is still supported in so far that we'll find a way

In all cases, you first need a bootstrap loader if your board
isn't ARC compliant (it probably isn't). Take a look at the
ARC loader "MILO", available from to
get an idea how Linux kernel can be loaded and launched. 
Included in the Milo package are a dummy kernel (actually a
hello world program) which has been very useful to check the

I would suggest to grab everything available and then to check
what can be used for your board. I already heard that it shall
run in big endian mode, which might be complicated since all other
platforms run little endian...

Feel free to post any questions you have. We'll try to give our
best to make your kernel working before xmas, but I hope you
have enough manpower available :-)


To Luc and Stoned: Would you please subscribe Michael? Thanks!
