[Buildroot] Unable to configure USB webcam in Buildroot

[Sourabh Hegde]

[-- Attachment #1.1: Type: text/plain, Size: 386 bytes --]

Hello,

I am trying to configure a Logitech USB Webcam for my NXP i.MX 8M board. I
have enabled CONFIG_MEDIA_USB_SUPPORT=y in the linux-menuconfig.
But when I do "ls -l /dev/video*" I get "No such file or directory" and
"v4l2-ctl --list-devices" shows "Cannot open device /dev/video0, exiting.".

Can anyone please let me know how to enable USB webcam in Buildroot?

Thank you,
Sourabh

Not really a Buildroot question, but that webcam probably uses the UVC
(USB Video Class) interface. Ensure you have CONFIG_USB_VIDEO_CLASS
enabled in your kernel and check dmesg when you plug it in.
