Jetson Orin Nano L4T carrier board downgrade

Hi, I have fresh unboxed NVIDIA Jetson Orin Nano Dev Kit 8GB with the official carrier board and managed to update to the “super” version by following the official NVIDIA instructions Initial Setup Guide for Jetson Orin Nano Developer Kit. This update brought my board to L4T 36.4.3 with JetPack 6.2.
I was able to run Jetpack 6.2 from SD card, but unfortunately drivers for my camera are designed for Jetpack 6.0.0 L4T R36.3.0. So firstly I tried to boot a system from an SD card that runs L4T 36.3.0, this part works, but I’m facing issue installing certain drivers—likely due to an incompatibility between the SD card’s OS (36.3.0) and the carrier board firmware (still at 36.4.3).

My question is:
Is it possible to downgrade the L4T version on the carrier board to 36.3.0 without relying on a host PC/recovery mode (i.e., using only the system installed on the SD card)? I found the updater package (nvidia-l4t-jetson-orin-nano-qspi-updater_36.3.0-20240424200557_arm64.deb) available, but I’m not sure if it can be used standalone.

Any guidance or experience with this scenario would be greatly appreciated. Thanks in advance!

Hi,

You need to prepare it to downgrade your Orin Nano.

That means it can be simply done using NVIDIA SDK Manager, where I could choose specific version of L4T and the old one will be erased/ swapped to new one on carrier board simultaneously flashed on SD card?

Or there are other steps need to be performed to change L4T version on carrier board using host PC/recovery mode?

Yes. If your device is a dev kit, and the sdk manager could do you mentioned.

Thanks
