Hi,
Found chipset "AMD SB7x0/SB8x0/SB9x0" with PCI ID 1002:439d. Enabling flash write... EC SIO is at 0x16e EC MBOX is at 0x3e (Shutting down IMC) SPI base address is at 0xfec10000
This means that firmware correctly responded to the command and most likely moved itself to internal RAM.
Verifying flash... VERIFIED.
EC SIO is at 0x16e EC MBOX is at 0x3e (IMC resume failed!)
This means that firmware was not able to continue at the end?
I have a couple of questions:
1) did you perform full power cycle (even unplugging the PSU)?
I suspect that the IMC may run even if main cpu is off. I also suspect it fully initializes only if performing this "cold boot".
2) what was the update? It was from original BIOS to coreboot? Does coreboot have a embedded IMC image? Does the IMC image start at the same location?
What we could additionally check is if the IMC firmware location does not match in source and dest image, bail out. Or if the base addr has been changed.
Thanks Rudolf
Hello Rudolf,
Here's more information; this email is quite lengthy. Please let me know how you would like to proceed. I should be getting my own SF100 soon, so my turn-around will be faster.
---
Using a DediProg SF100 in system programmer to unbrick; reprogram with previous AMI (original BIOS on the AMD board). NOTE: Needed to tell programmer software to auto-unprotect protected blocks before programming. Boot is Ok. Poweroff, reboot
---
Using flashrom (with IMC patch), flash coreboot base build for AMD Persimmon board. Passes verifying flash; but IMC resume failed. Poweroff - doesn't fully power off. Stops with "Power down."; manual poweroff
---
Reboot system, and able to ssh into system; no VGA from the board itself. No VGA is expected because I did not add a vBios to the coreboot image.
---
Trying to flash back the AMI original bios; fails with:

Power off, unplug board power supply, moving both jumpers (JP12, JP13 on pin 2-3) for 30 seconds to clear CMOS settings. Reboot; Retry flashrom AMI; outputs:

Try reboot; nothing Manual poweroff, unplug jumpers and power supply for 30 seconds Power on Nothing
