Can pluto have camera support for a video/image standalone application?

Bloodfield on Apr 23, 2022

I am trying to connect a webcamera to plutosdr in order to send pictures trough a wireless link via plutosdr

I have already tried to enable some buildroot packages like fswebcam, v4lgrab, libcamera and gstreamer in a customized plutosdr-fw firmware

However, the wecamera does not get listed as device, only gets detected:

dmesg output:

usb 1-1.3: new high-speed USB device number 4 using ci_hdrc usb 1-1.3: New USB device found, idVendor=090c, idProduct=f37d, bcdDevice= 0.00 usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.3: Product: SMI usb 1-1.3: Manufacturer: SMI

Does anyone who have tried something like this yet can help me out?

Does anyone have an idea of what configurations are needed or packages enabled or installed?

I am using:

Vivado 2019.1.3

Camera: Leopard LI-OV9712-USB-M8

Thanks

We could not figure out how to enable it trough buildroot or busybos. Tried serching the CONFIG and VIDEO in both interfaces, but it did not showed.

At the end, we tried appending "CONFIG_USB_VIDEO_CLASS=y" at the end of the text file plutosdr-fw/buildroot/configs/zynq_pluto_defconfig
However, after the make it did not listed the device

Is this correct?

Thanks,

This is also a followup from another question that a colleague of mine asked in another forum.
We append `CONFIG_USB_VIDEO_CLASS=y` to this config file `plutosdr-fw/linux/arch/arm/configs/zynq_pluto_defconfig`

However, nothing seems to happened, even with a different cammera.

outputs:

dmesg | grep "usb 1

If you have the proper drivers and perhaps also firmware build into the kernel things should work. The first thing is to attach the camera to a desktop PC running full blown linux with all modules installed.

Determine which modules get loaded and enable them on Pluto as well.
