custom g_webcam driver in yocto recipe

[alexandre_caron]

Hi,

I'm currently developping a camera application on IMX7 Dual and I use the webcam Usb Gadget. I had to modify the driver "webcam.c" located in ~/imx-yocto-bsp/build_folder/tmp/work-shared/imx7dsabresd/kernel-source/drivers/usb/gadget to chnage the resolution and the frame rate and it work well. 

My question is, it is possible to add those changes in a yocto recipe instead of the tmp folder ? It would be a lot cleaner and much more piratical to share with other colleagues. 

Thank you.

Hi alexandre.caron@teledyne.com ,

You can create your custom meta-layer and apply your patches using it. (you can share it with your colleagues.)

For creating your meta layer and apply your changes using yocto in kernel you can refer the below link:
