Hi,
Please try the steps and see if you can trigger the update:
[host]

  1. Overwrite the files in:
    Serial device hangs after closing, unable to re-open without first unplugging it - #9 by DaneLLL
  2. Boot target device in recovery mode and connect to host
  3. Run the command:
Linux_for_Tegra$ sudo ./build_l4t_bup.sh jetson-orin-nano-devkit mmcblk0p1
Linux_for_Tegra$ ./generate_capsule/l4t_generate_soc_capsule.sh -i bootloader/payloads_t23x/bl_only_payload -o ./TEGRA_BL.Cap t234
  1. Copy TEGRA_BL.Cap to target device

[target]

  1. Run the command on target:
$ ll /dev/disk/by-partlabel/esp
$ sudo mount /dev/nvme0n1p11 /mnt/
$ cd /mnt/EFI
# mkdir UpdateCapsule
# cd UpdateCapsule/
# cp /home/nvidia/TEGRA_BL.Cap .
With QSPI flash:
# cd /sys/firmware/efi/efivars/
# printf "\x07\x00\x00\x00\x04\x00\x00\x00\x00\x00\x00\x00" > /tmp/var_tmp.bin
# sudo dd if=/tmp/var_tmp.bin of=OsIndications-8be4df61-93ca-11d2-aa0d-00e098032b8c bs=12
  1. Reboot the target device
