6.20 USB host
The STM32MP157F-EV1 board provides 4 USB host port (2 dual USB Type-A connectors MB1262/CN18 and
CN20) by means of USB Hub USB2514B-AEZC. The USB2514B has a full power management for each USB
Host port. The default configuration of USB2514B is done in HW, thus I
2
C is not needed by default. However, if
required for a specific application, I
2
C may be accessed through MB1262/SB71 and SB68 to I2C2 as described in
Table 30.
