6.17 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 STM32MP157xAA3 through DCMI and I
2
C interfaces. RSTI, XSDN, PLUG signals
are connected to MFX.
The I2C is I2C2 that is shared with all the peripherals: audio codec, MFX, RGB LTDC, DSI LCD, and USB hub.
The camera I²C address is 0x3C.
Table 24 describes the IO configuration for the camera interface.
