[galla rao]

Hi All,

am trying to save NVRAM variables which are modifed in Uefi Payload, but i
could not save it.

what is the role of uefi_nvs.bin file?

coreboot/intel/mainboard/intel/bayleybay_fsp/uefi_nvs.bin




Even the boot order does not save into NVRAM variables


Can some one help me on this, Base address is given below


gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase   | 0xFFF60000
