Camera enablement (OV5647) for FRDM-IMX8MPLUS board

AN14376: https://docs.nxp.com/bundle/AN14376/page/topics/enable_omnivision_ov564

Wrt this post, I would like to enable camera on similar device FRDM-IMX8MPLUS Device.

I see, I am able to get some values and detection at 0x36 address which is OV5647.

I have tried to use .ko files or .binaries or .dtb of IMX8MPLUS EVK board. Somehow, I am getting errors like repeating logs.

Booting from mmc ...

Also, tell me how to remove previous saved environment as the device is stuck at same uboot even after rebooting...

My aim is to enable OV5647 on my FRDM-IMX8MPLUS board.

Any help is appreciated..
