[parisc-linux] STI Console problems on 735 and 755

[Phillip Beal]

Hey,

After all the help I obtained from this list, both through my posts and
through the archives, I've finally gotten the 735 and 755, that I have
access to, to boot and run linux.  However, as soon as it starts to
process init, the console screen becomes garbled.  The system continues
to boot, and I can access the machine via serial console and minicom,
but the physical console on the box, just prints garbage.  Is this
normal for this stage of development?  I couldn't see anything in the
archives, that said it was, so I'm wondering how I fix this problem, if
its been fixed before.  

Thanks,

Good to hear that your 735 and 755 start to boot!

What kind of graphics hardware is sitting on a 735 or 755?  I think
we've only ever looked at that on a 712 and 715.  

Can you use serial console in the meantime?

Both the 735 and the 755 have the following device, that seems be refer
to the graphics:

Coral SGC Graphics (10) at 0xf8000000, version 0x4, 0x0, 0x77, 0x0, 0x0

However, the 755 is known only to use mono graphics, even though they
both report the same info for the Coral SGC Grpahics. 

I hope this helps,

Yeah, serial works just fine.
