In the block diagrams the camera modules CAM_MCLK line is shown as coming from pin G36 of the esp32-p4.

But the schematic tells a different story;

On the ESP32-P4 we have CAM_MCLK_GPIO36 coming from the esp32-p4:

It has a 10K pullup (R10) to SOC_3.3V:

But then is not used!

There are two N/C (Not Connected) resistors (R27 & R109) on the connection to U35 (which drives the camera modules CAM_MCLK_1V8 at 1.8v)

But note that the connection shown as PXT24M is connected, and comes from X2, a 24 MHz CMOS crystal oscillator.

Which is correct? The Schematic or the block diagrams?

If setting up a camera driver on the Tab5 can we safely ignore setting up gpio36 and just assume the camera MCLK is permanently fixed at 24MHz?

Edit: This isnt a criticism, it's quite normal; The board was designed so that it can accommodate two different camera module units. And the decision about which one to use can then be made closer to production time. Circuit designers do this a lot; the appropriate components are added/removed at production time without the PCB layout needing to be changed.
