Re: rtVAX300 .. need help..



> 3. at first I need to make the kernel print out something.

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.
