[LinuxBIOS] Question about after Jumping to LinuxBIOS

[AlexHuang]

Hi all,

I am a novice about porting Linuxbios, and now my message stoped at "Jumping
to LinuxBIOS".

Before this message, I see the linuxbios will do copy_and_run. I also dump
the data in ths src address and dst address. The data in src and dst are all
0xFF.

Could someone tell me what should be next step? And what's wrong in my
linuxbios

Thanks a lot ~~

Alex

Please don't doubt post. What hardware are you using? Your ram, for some
reason, doesn't seem to be initializing correctly, or else your Super IO
is getting reconfigured, and not correctly. Is this still the Via Epia?
AFAIK, the EPIA (or rather, vt8601) has a lot of hardcoded registers,
which would have to be changed for your specific ram setup to match the
registers from the running factory bios. Look at raminit.c in
src/northbridge/via/vt8601. Also try running ram_check at the end of
main() in auto.c, to check if the ram is working correctly. The function
should already be there, just commented out, iirc.

Hello Alex,

great to see SIS interested in LinuxBIOS. Which board do you use?
Can you post a boot log?
