@nian 好的

Your current image is Jetpack 5.1.2 with L4T version r35.4.1. The mvcam driver included in it is relatively old, so the mv_probe.sh script cannot work properly. — For more details, you can refer to the comments at the top of the mv_probe.sh script.

In addition, please try running the following script and see if it shows continuous messages indicating that data is being received. If it still fails to receive data, please run sudo dmesg to check whether there are any error messages.

export WIDTH=2560 export HEIGHT=1544 export FPS=50 v4l2-ctl --set-ctrl roi_x=0 v4l2-ctl --set-ctrl roi_y=0 v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY v4l2-ctl --set-ctrl frame_rate=$FPS v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null

@veye_xumm 这样啊，好的麻烦您了，我再跟公司里沟通一下

@joe said in VEYE-MIPI-IMX462 on Seeed J401 Carrier Board + Orin Nano 4GB (JetPack 6.2 / L4T 36.4.3) – No /dev/video Device Detected:

Questions:
What could be preventing /dev/video0 from being created, even though the sensor is detected by the kernel?

Under normal circumstances, as long as the I2C communication is working, the /dev/video0 node should be generated properly. Based on my initial assessment, your issue likely stems from differences in the usage of MIPI CSI pins between the J401 carrier board and NVIDIA's official developer kit when paired with the Orin Nano core module. Since our DTBO is based on the device tree of NVIDIA's official developer board, it may not be fully compatible with the J401 out of the box. You can try analyzing the full dmesg output to identify any errors. I suggest reaching out to Seeed for further assistance on this issue.
