Xavier NX A/B Failover not work

Hello,

I used Jetson Xavier NX devkit with emmc(linux version: r3273) to test failover rootfs slot switching.
I destroyed slot A by this command:

sudo dd if=/dev/zero of=/dev/mmcblk0p1 bs=200M

And then I powered the devkit back on. In this case, slot A was certainly unable to boot. I expected the devkit to automatically switch to Slot B, but it didn’t—instead, it got stuck:

ERROR PARTUUID=3e3b5b0d-024a-4570-bc4a-952399c7f708 mount fail…

So I checked the forum posts and found that someone encountered similar issue: Xavier NX A/B Failover. The official staff stated that this problem would be fixed in versions later than r3541. However, for some reasons, my bsp can only be developed based on the r3273 version. Therefore, in the r3273 version, is it possible to fix this issue by manually modifying the BSP?

hello qian.yuan,

unfortunately, we’re usually not back-porting the fixes to earlier release version.
please also refer to JetPack 4 Reaches End of Life.
