Hi,

I don’t know much about VR series processors but I should be able to help with general MIPS stuff.

Any link to previous attempts? I’d like to know what went wrong.

Suspend and resume are rather hard to debug, in many cases the kernel just stuck at some point
and you have no way to know where it is because it is to early to make any output. Do you have access
to serial port?
 
Meanwhile kernel cores should be easy to sort out as long as there is a backtrace.

Btw I’ve got a NEC Sigmarion which have the same processor, I’m still struggling to get NetBSD
boot. It comes with a Japanese only Windows CE. I thought I should be able to interpret Japanese
via Kanji but I’m wrong….
