Camera_CLK (XCLK/MCLK) Source in STM32F746G-DISC Board.

[Rajssss]

According to the schematics of the STM32F746G-DISC Board, the Camera_CLK pin in the Camera Connector need to sourced from OSC_24M, I couldn't find form where. There seems no internally used pins for this as for others in the schematics.

Someone please help me out with this.

Can you see the X1 oscillator right next to that connector?

Can you use find/search to find the rest of OSC_24M connections?

[Rajssss]

Yeah, OSC_24M goes to REFCLK but I am not sure what is it.

and yeah I can see there's X1 oscillator there, but actually I am just getting started on cameras and never seen a dedicated oscillator for Camera clock.

So, do i need to configure or enable this oscillator while initializing the camera? if yes, how?

[Piranha]

There is nothing specific to cameras or ST. It's just an oscillator and it's one of a ways how to provide a clock signal to something. And it's EN pin is already hardwired with a pull-up resistor to 3V3 line, so there is nothing to enable in software.
