16 channel camera configuration issue

[solo_wh]

HI nvidia teams：

After completing my 12 channel camera configuration debugging, I continued to add 4 cameras and rewrote the new 16 channel camera dtb. However, I confirmed through the serial port that I could not enter the file system.
log：
log.txt (217.7 KB)

I checked the channel configuration of my port12-port15 through Sensor Software Driver Programming — NVIDIA Jetson Linux Developer Guide 1 documentation and Jetson Virtual Channel with GMSL Camera Framework — NVIDIA Jetson Linux Developer Guide 1 documentation. but haven’t found any issues yet
dts:
tegra234-p3737-0000+p3701-0000-dynamic.dts.txt (65.5 KB)

I think my problem is most likely with the use of stream0-6, but I haven’t found where the problem lies yet
Please help check the DTS（port12-port15） and logs，Any advices would be appreciated. Thanks

Hi,

For the camera basic functionality first needs to check the device and driver configuration.
You can reference to below program guide for the detailed information of device tree and driver implementation.
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/SD/CameraDevelopment/SensorSoftwareDriverProgramming.html?highlight=programing#sensor-software-driver-programming

Please refer to Applications Using V4L2 IOCTL Directly by using V4L2 IOCTL to verify basic camera functionality.
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/SD/CameraDevelopment/SensorSoftwareDriverProgramming.html?highlight=programing#to-run-a-v4l2-ctl-test

Once confirm the configure and still failed below link help to get log and some information and some tips for debug.
