Re: rtVAX300 .. need help..

I thought you already did this, by calling back into the ROMs? Or am I
confused? I'll assume I'm confused, that all the output you've got
working comes from bootblocks rather than the kernel.
"First make it work, then make it better." In this case, I would say
this means hack together a polled-only console device that blindly
assumes it's on an rtVAX300 and pokes the 2681 directly. Hack and
slash on the code as much as necessary - you can always go back to what
you started with if necessary. Get _something_ working this way. Once
you have kernel output of some kind, _then_ worry about backing out the
worst of the damage you've done and making a real 2681 driver work.
If my own experience is any indication, once you get something working
you'll find you can undo three-quarters of the hackery you did for
experiments.
