Hi,
I am developing coreboot along with Uefipayload for a custom board derived from CFL H RVP11 CRB.
Modifications are done as per the custom board and the board was booted and working fine.
I tried to reprogram the BIOS flash with FPT (Flash Programming Tool) from UEFI shell throws the below error and the operation failed.
"Error 167: Protected Range Registers are currently set by BIOS, preventing flash access".
What are the configurations need to be done in coreboot to allow program BIOS image with the FPT tool from UEFI shell?
Thanks & Regards, Moorthi S _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-leave@coreboot.org
