hello liviolima80,
it’s possible to update rce-fw remotely.
since rce-fw belong to bootloader, you may use the OTA payload to update bootloader remotely.
here’s an example, we’ve also tested and verified rce-fw update without re-flashing.
for instance,
(1) Please update rce-fw on your local host machine,
i.e. please update $OUT/Linux_for_Tegra/bootloader/camera-rtcpu-t234-rce.img with the latest rce firmware binary.
(2.1) You should also visit L4T page, jetson-linux-r3550 to download [OTA Tools] package.
(2.2) You may refer to developer guide for Preparing the OTA Payload Package section to prepare the OTA payload, and see-also Steps Performed on the Host Machine for reference.
(3) Running below commands to generate an OTA payload package, here’s an example to create OTA payload for only updating Bootloader for Orin Nano DevKit.
for instance, $ sudo -E ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh --external-device nvme0n1 -b jetson-orin-nano-devkit R35-5
(4) Here’s generated OTA payload, you may deliver this (via ssh) to your remote targets for running bootloader update.
$ ls $OUT/Linux_for_Tegra/bootloader/jetson-orin-nano-devkit/ota_payload_package.tar.gz
