Jetpack 5.1.3 : vi_capture_control_message: NULL VI channel received

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX

Use Xavier NX + EV9500M module, EV9500M模块与jetson之间只有一个reset脚，4lane的csi以及一路csi-clk信号，无需配置，上电即有数据输出，通过示波器测量信号都正常的. csi_clk is 297MHz，但是使用下面的命令采集，在屏幕上显示一个绿屏的窗口
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=UYVY ! videoconvert ! xvimagesink

各位大侠，有什么建议吗？

hello beta.guo,

could you please check developer guide to To verify the port binding result.
you may see-also Debugging Tips for troubleshooting.

however, is it possible to control your sensor to issue a reset while software side calling s_stream?
it’s due to a typical camera application running cycle, the driver will Power On the sensor, Start Sensor Streaming, sending relevant v4l2 controls, and finally power off the sensor.
according to above, there should be LP sequence, and also some delay for MIPI signaling coming to CSI/VI.
