I'd like to report success with using flashrom 1.2 to flash a Supermicro
X11SSH-TF (Intel C236 chipset). The hardware had already been flashed with
Coreboot using an external programmer, and I'm trying to ascertain if
flashrom can be used to flash updates to it.
I'm attaching full logs, apologies for the slightly crufty format, these
are from a serial console.
There are a couple of things I'd like to check with you before I decide
that this is safe to use in the wild:
1. Flashrom complains that:
Warning: Setting Bios Control at 0xdc from 0x8b to 0x89 failed.
New value is 0x8b.
SPI Configuration is locked down.
2. After a cold boot, the hash I read back from the flash does not match
what I wrote to it. If I do a -r immediately after a -w, it does match. See
the 2nd log attached for the mismatch.
Does (1) matter in any way? For (2) I'm assuming ME/Coreboot/something is
locking down regions of the flash, and that lock only gets removed when
Thanks & keep up the good work,
