We planned get back to ECC issue in coming month by exercising 2 ideas from forum [1]: 1. Mentioned by Kyösti usage of UEFI payload and MemTest86 v7 Pro Edition. I already started work on payload [2] and have ability to boot to UEFI shell, but now working storage drivers yet. 2. Use rowhammer_test mentioned in last post [1]. But it looks I completely forget mentioned bug. I assume above scenarios will not work in light of mentioned bug ? We know which version of AGESA breaks apu2/3. It is [3]. We tried to disable graphics in various ways, but nothing helps. @Kyösti, maybe it is related to PspMboxBiosCmdDramInfo and PspMboxBiosCmdExitBootServices commands and PSP support in coreboot ?
