Hi,
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 writing?
Thanks & keep up the good work,
Martin
