[flashrom] Flashrom erase failure

[Racine, Michel]

Greetings,

I have an AMD Persimmon dev board. I built coreboot and flashed it successfully; the board was operational.
I have attempted to flash the original rom (obtained before flashing coreboot with flashrom -r).
When I attempted to flash the original rom, I get the output below.

If possible, could you please refer me to the proper documentation to resolve this issue.

Thank you,
Michel Racine.
