@WayneWWW We have discussed this issue previously as well , After updating to L4T 32.5.1, I am unable to update my DTB with custom camera drivers. This time around there is no nvbootctrl Slots A/B issue as ROOTFS A/B is disabled and only Slot 0 is in use for L4T 32.5.1. DTB Build does not update…

Can you compare the uart log between working case and non working case? I checked your log yesterday but it still read the dtb from emmc. Not sure why your dtb didn’ get update. Also, this release is kind of old, so I am not sure whether there is a bug or not.

Previously Last Year , if you remember , My slot A was getting flashed and slot B was booting due to the wrong priority order .
