HI Dion,
Good to know that the B0274 is 4 lane capable. On my Orin NX 16GB development kit CAM0 is closer to the power. But CAM0 is only 2 lane capable as per NVIDIA.
I am using Jetpack 6.2 tegra_release 36.4.3. I have connected the B0274 to CAM1 which is the only port that is 4 lane capable on the development kit. The default nv_imx477.ko available in this JetPack is getting used.
I am using jetson-io but I don’t see the overlay names like “Camera Arducam Dual” in the display as see in the WiKi (Jetson-io - Arducam Wiki). Might be because it is for a Nano and older JetPack.
I have tried “Camera IMX477 Dual 4 lane / tegra234-p3767-camera-p3768-imx477-dual-4lane.dtbo” but this overlay does a 4 lane setup for CAM0 CSI A-B, and 2 lane setup for CAM1 - CSI C/D. But, on the Orin NX development kit CAM0 only CSI-B is used and therefore only 2 lane. So, with this overlay B0274 is sort of forced to 2 lane mode on CAM0 and and programmed to 2 lane mode on CAM1. So, I don’t think “Camera IMX477 Dual 4 lane” is not the correct overlay for B0274 on CAM1.
So, I wrote an overlay for 4 lane on CSI C-D. Here it is below. Can you please let me know if there is something wrong in the overlay below that jumps at you?
Thanks
