Camera
Through the MB1262/CN7 connector, a camera module mounted on a daughterboard MB1379 is provided.
MB1379 is a 5 Mpixels, 8-bit color camera module based on OV5640 image sensor, clocked from a 24 MHz
crystal (MB1379/X1). It is supplied by 2V8.
6.17.1
Camera interface
MB1379 is connected to the STM32MP157xAA1 through the DCMI and I
2
C interfaces. RSTI, XSDN, PLUG
signals are connected to MFX.
The I
2
C is I2C2, which is shared with all the peripherals: audio codec, MFX, RGB LTDC, DSI LCD, and USB Hub.
The camera I
2
C address is 0x3C.
