I/O Configuration
MFX_O2 XSDN – Camera PWDN, active high
1.
Available on the MB1262/CN7 connector, but not used in the MB1379 module
6.18 1 Gbps Ethernet
The STM32MP157F-EV1 board provides a 1 Gbps Ethernet feature by means of an external physical interface
device (PHY), R
TL8211EG-VB-CG. This PHY is connected to the STM32MP157FAA1 gigabit reduced medium-
independent interface (RGMII), and is clocked from a 25 MHz crystal (X1).
The Ethernet PHY is supplied by 3V3. It generates its own supply 1V05 and digital/analog 3V3.
LD1 LED blinks to indicate data transmission.
The Ethernet module connector MB1262/CN6 is for STMicroelectronics internal use only.
6.18.1 RGMII interface
Table 26 describes the I/O configuration for the Ethernet interface.
