Starterware/AM5728: Camera module not working

Tool/software: Starterware

Hello,

I am working on AM5728 Sitara board.

I want to use TMDSCM572x camera module for AM5728 but camera is not detecting. I have seen all similar queries and the only solution/fix suggested in all is to connect the module properly that i tried but still not working.

I am using revision C camera module but there is no any schematic for revision C. Can you please provide me Rev. C schematic so, i can test GPIOs.

Please reply if you have any solution.

Regards,

Prashant

Hi Biser,

Thank you for the suggestion.

I have Rev C camera module. So it has ov10635 sensor module.

I include am57xx-evm-common-cam-ov10635.dtsi in am57xx-evm-reva3.dts & am57xx-evm.dts and build kernel source.

Then i build kernel and copy dtb to /boot/

Above steps helped me to get video device up.

Now i am getting green image and errors as bellow.
