Hello LinuxBios elders,
I'm sorry to bother you.
I'm begining to study LinuxBios and I have some problem in it.
Hope you can give me some idea.
My target board is an AMD Opteron (chipset: K8 / 8111 / 8131) mainboard,
it is similar to Tyan s2880 / s2881 / s2882.
So I base on Tyan s2880 to change some config file to compile a linuxbios.rom,
but it doesn't work.
Following is what do I changed in s2880:
1. I changed the payload path in targets/tyan/s2880/Config.lb.
2. modify src/mainboard/tyan/s2880/Config.lb as 42812-pci.txt. ( as attachment )
I don't know is it correct that I modified. If you have interest you can refer to Attachment.
3. generated irq_tables.c by getpir.c and replaced the original one.
compile and burn it in rom.
After I boot up the target board, it always alert emergency beep.
Then, I unmark some debug message in 'src/northbridge/amd/amdk8/raminit.c' to see where is it hang.
The last step is hang on setup_default_resource_map() in 'src/mainboard/tyan/s2880/cache_as_ram_auto.c',
I can see it from serial console ( as attachment again. )
Is there any configuration I should change, and I didn't do ?
How can I debug it ?
Thanks a lot.
