Hello all. I trying to add A8-7680 support to A68HM-P33.
There is A68HM-P33-V2 witch has same chipset and supports Carrizo.
Also latest bios for A68HM-P33-V2 has A8-7680 microcode (but A8-7680 no in support list).
Latest bios for MSI A68HM-P33: 7721vY4.zip
Latest bios for MSI A68HM-P33-V2: 7895v15.zip
I tried to add A8-7680 microcode to MSI A68HM-P33 but it not works (or my new cpu from aliexpress is dead).
Maybe it needs something else to support Carrizo?
Patched uefi with A8-7680 microcode and nvme support: E7721AMS_PPP_2.Y40
I took the next steps in the hope that my new processor was alive.
Also I tryed to add whole AmdProcessorInitPeim from A68HM-P33-V2.
But in A68HM-P33 firmware no place for AmdProcessorInitPeim from v2.
And in A68HM-P33 firmware a lot of unused space in FFSv2 partition with DXE drivers, but not enought space in partition with PEI modules.
I not found information about how to resize FFSv2 partitions.
There my unsuccessful try to do that with hex editor: V1_PART8.rom
Maybe easier to modify A68HM-P33-V2 uefi to add support A68HM-P33?
Update:
The problem resolved itself.
It turns out that the A68HM-P33-V2 firmware is suitable for the A68HM-P33 board. (For unknown reasons, the first attempt to flash the A68HM-P33-V2 via a BIOS update failed, but on the second attempt after recovery to stock uefi through the programmer it working)
A8-7680 support has appeared. Parallel port settings are missing. The A8-7680 is unstable if the “Core C6 state” is enabled.
Also A68HM-P33-V2 has update checksum, rollback to stock without proggramer may not work.
