Max96712 &&max9295a gmsl 4 lan mipi Interface conflict problem

Hello everyone, I use max96712 and max9295a to debug the gmsl2 6G camera, and connected 4 cameras, of which camera 0 and 1 are connected to jetson’s CSI A (port-index=0), and camera 2 and 3 are connected to CSI C (port-index=2); Currently, the two cameras running CSI A/C separately can produce images normally, but the cameras of CSI A and C cannot be run at the same time. For example, 4 cameras video 0~3, 0~1 corresponds to CSI A, 2~3 corresponds to CSI C, when I v4l2-ctl --stream-mmap -d /dev/video0, v4l2-ctl --stream-mmap -d /dev/video2 cannot produce images, and when I ctrl+c to close video2 when video0 is running, video0 will also be affected and cannot produce images; I don’t know why this happens, can you give me some suggestions?

Note: Although the image cannot be displayed, the gmsl-deserializer 96712 does receive data, so I think it is a MIPI configuration problem.

Hi @shuisheng.peng, which Jetson device are you using?

Then I can refer you into the correct sub-category for this device.

Thanks!

hello shuisheng.peng,

please setup Jetson Virtual Channel with GMSL Camera Framework.
you should have 1st set of camera on CSI-A for using VC=0/1,
and also, 2nd set of camera on CSI-C for using VC=0/1.

ok thanks
