Roda RK886EX troubles

[Vitaly Chertovskih]

Hi!

I'm experiencing some troubles in installing coreboot on Roda RK886EX.
Please, help me.

Is there some manual about installation coreboot on Roda?

I build coreboot, choosing Roda motherboard, adding compiled SeaBIOS image
(I download it from coreboot.org), and including VGA onboard rom, grabbed
from /dev/mem as described in howtos on coreboot.org. But, after flashing
using flashrom, nothing happens. Screen blinks once, and nothing happens at
all.

I include my .config file, maybe it helps...

Please, help me. What am I doing wrong?

Try connecting a com cable and see if there is any output.

Can you please send a serial console log along?

Attaching serial port log.
Thanks!

At first glance, it looks like there is something wrong with your mtrr 
setup. Maybe something weird about memory region allocations.

Thank you. There's a problem when coreboot tries to execute the VGA
ROM. You mentioned that the ROM was extracted from /dev/mem. It would
be even better if you could extract the VGA ROM from a BIOS image on
disk, instead of from the running system.

Another approach would be to disable execute of the option ROM in
coreboot. This is not something coreboot can do well. If you need an
option ROM (such as a VGA ROM) then it's better to use SeaBIOS
because you then get a complete BIOS environment in the system, and
option ROMs want that very much.
