Cannot use CSI Camera after downgrading Jetpack

Hello,
I have a Jetson NX running Jetpack 4.6 and was configured to use 2 IMX477 cams.
But for a project specific reason I need to downgrade the Jetpack to 4.5 so I swapped the SD card to a Jetpack 4.5 version. The CSI cameras are visible but I cannot start any pipelines. Even a simple gst-launch command fails with the error:

Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:645 No cameras available

I have tried this with 3 different NXs and same issue happens. Is there any extra setting persisted on board?
Note that the SD Card with Jetpack 4.5 is cloned from an NX which is working in JP4.5 setup and not flashed from scratch.
I have also tried to reinstall the arducam drivers.

Thanks.

hello marmikshah,

did you simply swap the sdcard with JP-4.5, but the platform is actually flashed with JP-4.6?
here’s rollback protection and it also had dependencies with kernel and kernel-dtb binaries.

instead of downgrading Jetpack, you should flash pure JP-4.5 for confirmation,
thanks

Hey,
Thanks for you reply. Yes I simply swapped the SD Card as that SD was originally used on the same NX before I flashed a new SD card with JP4.6 for this NX.
So does this mean that there are some settings persisted in the board causing this?

I will try to flash JP4.5 and try.
Thanks!
