I'm porting LinuxBIOS to nVidia's CK8-04 (nForce4) chip. Currently, the serial port is working and I believe the soft reset is working OK.
It seems that the smbus is not being setup properly. Any suggestions are most welcome. Attached below is the serial output.
I will follow up with more useful tracing info from the serial port later such as enabling CONFIG_SERIAL_POST. Any other suggestions for tracing and debug are welcome too.
Sincerely,
Ken Fuchs kfuchs@winternet.com

I'm having trouble with the smbus and reading the SIMMs SPD.

I guess you need to create ck804_early_smbus.c to read spd rom. You can refer some driver from Kernel or Lmsensors...and nvidia chipset documentation. I change that from amd_early_smbus.c
or
create one fake_spd_rom function (dump from Linux with other MB) for a test.

My xxx_early_smbus.c was working fine.
It was the smbus read routine in xxx_smbus.h that was broken. It is now fixed. There be DIMMs. ;) Isn't working RAM great!
Yh Lu, thank you very much for your suggestions.

sure wish we could get a release. Are you doing reverse engineering or ...

I'm following what little documentation I'm able to locate. Documentation on CK8-04 exists, but not what I need as far as I can tell.
I could try seeing how the PhoenixBIOS does this, but I'd prefer good documentation on the CK8-04. Is anyone aware of any CK8-04 documentation useful for porting LinuxBIOS to the CK8-04 that isn't covered by an NDA?
Thanks!

NDA should be enough.
Besides that there is one Internel text file. But they will not give that to you.
Till last Sep. I make all works except SATA and NIC.
