Anvil, jetpack 6, 8xC1 cameras, some cams not detected

[franzrammerstorfer]

Following the installation guide from https://tier4.github.io/edge-auto-docs/getting_started/getting_started_with_anvil.html
we have issues on our setup

• Anvil PC (jetpack version 36.4, Ubuntu 22)
• 8x C1 cam

to get all cameras working. There are only /dev/video0 up to /dev/video4 devices, ie. 5 cams, the rest are missing.

Hence, we tried to generate a new dtb file (assuming the 'default' file /boot/tier4-isx021-gmsl-device-tree-overlay-anvil-r36.dtbo does not support 8 x C1), but the script
https://github.com/tier4/tier4_automotive_hdr_camera/blob/main/tools/dts_generator/tier4-imx490-gmsl-device-tree-overlay-anvil-r36.dts
does not work -- the option parser seems to dislike the argument L4T R36.4 (currently, python3.10 is installed)

So, here are our questions:

• what is the correct python version/dependencies to get the dts generator script running (directly on the anvil with jetpack 36.4)
• how can we make sure that the driver/device-tree is configured for 8xC1
