Interface ov5647 mipi camera module with IMX.8QM

[kiran0472]

Hi ,

I am trying to integrate OV5647 Camera module with IMX.8QM custom board using MIPI CSI Communication. But, kernel is getting Crashed when it is trying to create media link.

Please find the below logs & Device tree Enabled syntax.

Please kindly provide me some solution.

Which version of BSP are you using?

Could you send me your board dts file to me for double check?

How the camera connect on your board?
