@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.

@joe The RAW-MIPI-AR0234M is a MONO camera that has no color information and therefore does not support the UYVY data format. Please refer to this link below:

@joe The software part of the work seems fine. Next, we need to check if the hardware connections are correct, paying particular attention to the orientation of the FFC cable.

@joe yes
