Is it able to upgrade firmware&system through network?

We have some boards that they are running on Jetpack 5.1.1, we want to upgrade them to Jetpack 6.2, can we do it through network?

Hi,
The working solution is to do image-based OTA update to upgrade to r35.5.0/r35.6.0 first, and then upgrade to r36.4.3. Please refer to

Software Packages and the Update Mechanism — NVIDIA Jetson Linux Developer Guide

thanks, I will try it.

the doc is kinda confusing, it says:

  a. Download R35.5.0 BSP, sample rootfs, and OTA tools package, and then extract them.
  b. Generate the OTA payload package from R35.4.1 to R35.5.0:
     $ cd Linux_for_Tegra
     $ sudo ROOTFS_AB=1 ROOTFS_ENC=1 ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh \
       -i ekb.key --external-device nvme0n1 -S 24GiB jetson-orin-nano-devkit R35-4

but extracting them does not appear a Linux_for_Tegra, there’s a Linux_for_Tegra folder both in BSP and ota tools extracted folder, and if I use the folder in ota tools, it will report missing some scripts, so I combined them into one folder, then it reports missing rootfs, then I put sample rootfs into that folder, then I execute command:
sudo ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh --external-device nvme0n1 -S 24GiB jetson-orin-nano-devkit R35-3
It failed with reason: /home/dennis/Downloads/l4tr35.5.0/Linux_for_Tegra/rootfs/boot/extlinux/extlinux.conf is not found, exiting...

Hi I generated OTA payload of 35.5.0 and 36.4.3. The 35.5.0 upgraded successfully, but after 36.4.3 reboot, the nvidia logo displays for seconds then my screen reports input timing not supported by the monitor display, and the fan on orin nano stoped.
