Hello

i am having a issue, i need to use teh smartDMA to cocnet the camera OV, and use the enet port, but i am surpriuses that they are sharing pins, so i can not use samrtDMA at the same time that the ethernet, so what option i can do? i can sue the camera in other port ?

Hi @eng_jim714

The pins required to configure the Camera module are duplicated with Ethernet.

If you want to use both of them.

You can refer to this article.

Hello thank you for the reply, i implement that turoail but i have a issue:

I can not flash the board if i dont remove the camera.

How i can just take a single picture? i tried to use kCAMERA_InterfaceNonGatedClock

to call every time the startSmartData function , but i am getting only black frames or getting mesh images like the attached one.

Thank you again

Hi @eng_jim714

You can try to rework the camera pins by changing the SJ16, SJ26 and SJ27 from right side to left side.
