How to apply a custom ISP for camera module in JetPack 5

Hello all,

I’m working with a custom GMSL2 - MIPI CSI2 camera module on Jetson AGX Xavier, i’m able to capture frames perfectly using LibArgus, i used a camera_override.isp file to override isp parameters, and that works fine tho.

I ported my driver to JetPack 5.0.2, i’m able to capture frames too using LibArgus, but when i applied the ISP modification using the commands below :

1. If there are any nvcam_cache_#.bin and serial_no_#.bin files under /var/nvidia/nvcam/settings on Jetson, delete them.

sudo rm /var/nvidia/nvcam/settings/nvcam_cache_*
sudo rm /var/nvidia/nvcam/settings/serial_no_*
2. Copy camera_overrides.isp in the correct location:

cp <path>/camera_overrides.isp /var/nvidia/nvcam/settings
3. Do below commands:

sudo chmod 664 /var/nvidia/nvcam/settings/camera_overrides.isp
sudo chown root:root /var/nvidia/nvcam/settings/camera_overrides.isp

But that broke the pipeline, and i’m not able to capture anymore (I had to delete the ISP binaries)

Does the syntaxe has been changed in JetPack 5 for the camera_override.isp file ?
Can you please tell how to apply the ISP file or what have i to change in the isp file i was using in Jetpack 4 to make it work on Jetpack 5 ?

Thanks

Could you remove some ISP parameter from the overrides isp file to narrow down which once cause the problem.

Thanks
