Details about some LEDs:

  1. ↑ Jump up to: 1.0 1.1 1.2 1.3 LD3, LD4, LD6, LD7: some user LEDs are used to reflect the system activity, while the others are left free for use by the application, as explained in the LEDs and buttons on STM32 MPU boards article
  2. ↑ LD5: flashes red if the STLINK-V3E connection is not established, green otherwise
  3. ↑ LD2: turns red if a USB Type-A connection is established
  4. ↑ LD1: turns green if the power connection established

4. Board connection↑

The connections shown in the picture below are the ones recommended to start with the STM32MP135x_DK Discovery kits. As shown in the board overview, other connectors are available for these boards (for example CSI-2).

  1. ↑ Jump up to: 1.0 1.1 Warning: the I2C5 is used to communicate with several on-board peripherals but is also available on the GPIO expansion connector. So, it is important to ensure that new components added on the I2C5 connection do not disturb the bus behavior.
  2. ↑ Jump up to: 2.0 2.1 Warning: the I2C1 is used to communicate with several on-board peripherals but is also available on the GPIO expansion connector. So, it is important to ensure that new components added on the I2C1 connection will not disturb the bus behavior.
Info white.png Information
No SDMMCx function is available on the GPIO expansion compared to the usual GPIO expansion connector.

6.2. User buttons and LEDs↑

The GPIO assignments for the user buttons and LEDs are described in the following table. Refer to the article LEDs and buttons on STM32 MPU boards to get information on the functional mapping for each one.

GPIO for user buttons and LEDs
