Hi,
After connecting a USB camera to my Jetson Orin Nano, the camera is detected via lsusb, but I encounter an error when trying to list devices: cannot open device /dev/video0. Additionally, when I check the modules.builtin, the v4l2 module is not listed. Could you provide guidance on resolving this issue?
Hi,
I have downloaded the BSP sources and toolchain from the Jetson Linux R36.3 release Jetson Linux 36.3 | NVIDIA Developer and followed these steps:
- Extracted the BSP sources and followed below link:
Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation - Configured the kernel with
make defconfigand further customized it withmake menuconfigto build multimedia drivers as inbuilt modules. - Rebuilt the kernel on my host PC and replaced the Jetson Orin Nano’s kernel Image with the newly built Image.
Despite this, the V4L2 module is still not recognized or listed on the Orin Nano. Could you provide guidance on potential causes or additional steps required to ensure proper integration of the module?
You would also have to build and install all of the kernel modules in most cases.
If you monitor “dmesg --follow”, then what new log lines show up as a result of plugging the camera in to USB? Also, does this particular camera use the standard USB video drivers? Sometimes they require a custom driver. Although USB does have some drivers which come with it, technically those drivers are not part of USB itself; upon plugin, a driver able to run that device would take ownership, and this would be reflected in the logs. It is possible that the driver does not exist (such as a missing or failed module load or a custom driver being needed).
Thank you for the response.
I’m trying to load the UVC Driver, But I’m getting the fatal error!
Could you provide guidance on resolving this issue?
Do you see file “/proc/config.gz” on the running system? Can you get a copy of that and post to the forum?
