Question about Leopard Imaging's 8 fisheye cameras #47

Open tackgeun opened 2 weeks ago

tackgeun commented 2 weeks ago

Dear Support Team,

I hope this message finds you well.

I am reaching out for assistance with activating my camera on the NVIDIA Jetson AGX Orin development kit. Specifically, I am trying to install 8 OWL cameras (LI-AR0234CS-GMSL2-OWL) with the LI-JAG-ADP-GMSL2-8CH (P3762-A03) board and have encountered some issues during the installation process. I found that 4 owl cameras works well with argus_camera util, while 8 owl cameras appeared in /dev/video0~7 but only 4 cameras are activated and possible to capture frames.

Issue #1: how to modify device tree to support 8 owl cameras? I use nova-orin devkit for setting up camera driver. However, it seems that this setting only supports 4 owls + 4 hawks setting for 8 cameras. I have noticed that /boot/tegra234-p3737-camera-p3762-a00-overlay.dtbo contains the hard-coded definition of device tree for 4 owls + 4 hawks.

Could you give the original location of the device tree source of /boot/tegra234-p3737-camera-p3762-a00-overlay.dtbo?

Issuses #2: Is there any way to activate current 8 owls cameras?

Thank you in advance for your help.
