We have CoreExpress Module with Atom 3815 by Kontron. It works perfectly with the original Phoenix BIOS (full functionality).
I am making our initialization program with FSP for BayTrail I E3815.
I have success returning from first Function TempRAMInit
After I am calling second function FSPInitApi
I have the following:
port 81 - 0x01 and port 80 - 0x2F then 0x33
As far as I understand according #523922
port 81h port 80h
0x01 0x2F Set Init Done
0x01 0x33 ???
Also coreboot_spi.bin from 554416-byt-cb-mr6 stops on post codes port 81 - 0x01 and port 80 - 0x2F.
Why does coreboot_spi.bin not reach to the end?
And please help to understand post codes: 0x01 0x33.
0x01 and 0x2F - are the last post codes in the FSPInitApi function?
and then program must go to the ContinuationFunc??
If it is true why coreboot_spi.bin stops on these post codes?
Thank you in advance!
