Hello.
I am porting a SERDES camera to orin nx, but the results are abnormal as shown in the screen below.
DTS is set as follows.
pixel_phase = “uyvy”;
active_w = “1920”;
active_h = “1200”;
serdes_pix_clk_hz = “225000000”;
pix_clk_hz = “69120000”
//1920x1200x30 (width * height * frame rate)
//serdes_pix_clk_hz = (deserializer output data rate in hertz) * (number of CSI lanes) / (bits per pixel).
//serdes_pix_clk_hz = (1800000000*2)/16 == 225000000
I attached “cat /sys/kernel/debug/tracing/trace”'s result

Please help to port the cam
Thank you in advance for prompt response.
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.

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