How to update BMC under EFI Shell?

Preparation:

The BMC image file and BMC update tool should be at hand, here’s the update tool:

Step:

Decompress “uflash_v12207.zip” under a bootable USB drive.
Put the BMC image file you wish to update to in the same directory.
Boot up your system with UEFI: Built-in EFI shell.
(Press F11 while POSTing to enter boot menu and choose it)
Execute: socflash.efi if= *image_file_name*
Wait until the update is finished. (It will show a message like “Update Flash Chip OK”)
Reboot and check the BMC version in the BIOS page.

*If BMC version doesn’t show up, please disconnect AC power from the system for at least 20 seconds, then plug AC back on and check again.

Done!
