2. Execute the A/B update process through these steps:
a. Go to the directory where you copied the BOOT.BIN in step 1.
b. Type sudo xmutil bootfw_update -i <location of new BOOT.BIN>.
c. The tool returns the image (A or B) that is updated, and is marked for boot on the next
boot.
d. You can verify the updated status of the boot rmware using the sudo xmutil
bootfw_status ulity.
3. Power cycle the device or press the board reset buon.
4. Aer restart, Linux must fully boot with the new boot rmware to verify funconality. This is
completed by execung a sudo xmutil bootfw_update -v command to validate the
successful boot against the new rmware.
Note: This step must be completed on the plaorm restart immediately following the update. If not
done in this order, on the next restart the plaorm will fall back to the previous boot paron.
5. Aer reboot, verify the updated status of the boot rmware using the sudo xmutil
bootfw_status ulity to conrm the expected image revision, selecon, and bootable
state are correct.
