A dt-overlay-mchp for adding two cameras for mpfs_video

[alihgh1993]

Hi,
I have a PolarFire SoC Video Kit, and I want to set up both of its cameras.
For now, I have bitbaked the mpfs-dev-cli image, but I am only able to get one of the cameras working.
How can I enable the second camera?

Hi

Currently, the video kit reference design includes only one enabled camera.

Thanks,

Thanks for your reply

So, what is the procedure to add the second camera?
I added th FPGA block design for the second camera based on the first camera design.
I also changed the devicetree to add the second camera but I did not get any result.
Should I also change the kernel modules?

Thanks

Hi,

If the FPGA design and device tree overlay have been correctly added, and the overlay file (dtbo + some-spi-client-header) has been included in the Libero SPI data client, you should be able to see two nodes, /dev/video0 and /dev/video1, after booting the board. Each node corresponds to one camera.

Thanks

Hi,
Thanks for your response.
I should search more about spi-client-header, because I dont know what is it and why is it related to the camera.
I thought I only need to modify the I2c of the board not the spi

Thanks
