Hello. Dear Coreboot team.

Thank you for your effort for Coreboot.

I'm from China.

My name is Guangzhe Lee. and I'm new in Coreboot.

I'm porting Coreboot to Gigabyte GA-945GCM board( LGA775socket / i945GC /
ICH7 / IT8718F ).

Romstage passed successfully, but after jumping to Ramstage console message
don't appear any more.

I tried to debug by GDB (using ttyS0), but it also fail.

I try the POST code, but the post card always displays "2C"->"2D"->"2E" ->
"2F". My post codes don't appear on the post card.

 

Please help me.

- How can I fix the problem.

- How can I fix gdb problem.

 

I'm sending 

  -  gdb message   and

  -  the console log of the booting.

 

Thanks and regards.

Guangzhe Lee
