To summarize:
Proprietary BIOS:
- Erasing the chip was tested, reading from the chip gives you all 0xFFs
after erase.
- Writing the chip after erase was tested, verify successful.
correct
LinuxBIOS:
- Erasing the chip fails, only a few bytes are changed (if any).
- Writing fails as well because erase failed.
correct
I need the exact LinuxBIOS revision you are using and superiotool dumps under proprietary BIOS and LinuxBIOS. I have a suspicion about the cause of the failure. Please state your exact board revision as well.
