Flashing your EDKII firmware

Using a UEFI Shell

The following describes how to flash your system’s EDKII firmware using a UEFI Shell, which requires an empty FAT32 USB drive and your AVA Developer Platform, at first, being turned off with all USB ports unused.

IMPORTANT: It is strongly suggested that you have a DediProg and DB40 board before flashing the firmware using UEFI Shell.

How to boot your system with UEFI Shell?

— To flash your both EDKII firmware, do the following:

Shell> FS0:
FS0:\\> ls
FS0:\\> cd ComHpcAlt_tianocore_atf_2.04.100.07
FS0:\\> capsule.nsh

A script name “capsule.nsh“ would help you to execute both EDKII firmware flashing and reboot the hardware automatically. Please wait for ~2 minutes for this process to complete.

Note:

  1. Capsule operation has been reconfigured since v2.04 and downgrading from v2.04 to v1.07 is not supported

  2. Capsule.nsh script can automatically distinguish your hardware between A1 and A2 to upgrade the corresponding EDK2 FW.


Once the update is finished, please double-check that the EDKII firmware is of the correct version by repeating step 6-A.
