Hello,


Our product uses a Baytrail with Minnowboard Max bios firmware ( version
0.93). Every now and then we see SPI flash corruption due to power cuts
while the unit is booting which causes the unit not to boot anymore. After
investigation we noticed that the VPD area is all FFs (address
44000->47DFF0).


We have noticed that the Bios while booting writes to the flash from
several places in the code, which is if interrupted most probably is
causing the corruption.


Why is the bios writing all these configurations to flash while booting, is
it to optimize boot time? is it ok if we disable the bios writing to flash
completely to protect ourselves from corruption?
