Hi

I have the same problems. UEFi settings are not saved. And the boot order
is the UEFI settings? But in my case it’s coreboot 24.02 + edk2.
I turned on debugging mode - there are no messages about errors in writing
to the bios spi flash and so. How else can this be debugged?
Which UEFI module/driver is responsible for this?
Flash write to bios region is available - I can update the this region.

Best regards, Dmitry
