"Warning - bad CRC" message after flashing EDK2

ROCK 5 Series 5 ITX/ITX+
1

Hello
After flashing EDK2 firmware I am seeing this message in the UART console output -
“*** Warning - bad CRC, using default environment”. Is it because EDK2 blanks out the original u-boot saveenv settings? Do I need to do anything to make it go away or is it harmless and can be ignored?

The system boots fine and is useable with Armbian.

Thanks

Check and list partitions ; I think it uses still boot.scr method, not EFI. For that you need efi/boot/bootaa64.efi on extra boot partiton. Settings should go in SPI-flash, like a PC BIOS and not in some uboot env file.

I setup my system in UEFI to boot from EMMC EFI partition correctly with grub-mkconfig and now the error is gone.
