Three different OV5640 modules are supported using the 15-pin FFC connector on SK-AM62: - Digilent PCam 5C - ALINX AN5641 - TEVI-OV5640-*-RPI The Digilent and ALINX modules supply a 12Mhz XCLK to the sensor, while the TEVI module supplies a 24Mhz XCLK, thus requiring a separate overlay. These overlays can be used on other boards of the SK-AM62* family that have a 15/22-pin FFC connector, so we name the overlays with the prefix k3-am62x-.
