Details about some LEDs:
- ↑ 1.01.11.21.3 LD5, LD6, LD7, LD8: some user LEDs are used to reflect the system activity, while the others are left free to be used by the application, as explained in LEDs and buttons on STM32 MPU boards article
- ↑ LD4: flashes red if ST-LINK/V2-1 connection not established, else green
- ↑ LD1: turns red if USB Type-A connection established
- ↑ LD3: flashes green when Ethernet connection established
- ↑ LD2: turns green if power connection established
4 Board connection[edit]
The connections shown in the picture below are the ones recommended to start with the STM32MP157x_DKx Discovery kits. As shown in the board overview, other connectors are available for these boards (for example HDMI).
5 Boot related switches[edit]
The following table defines the different combination of the boot mode selection switches:
![]() |
"Boot 1" is grounded (always 0) on the Discovery kits |
Boot mode | Boot 0 | Boot 1 | Boot 2 |
---|---|---|---|
Forced USB boot for flashing |
0 | 0 | 0 |
Not supported | 1 | 0 | 0 |
Engineering boot | 0 | 0 | 1 |
microSD card | 1 | 0 | 1 |
Below the corresponding configurations of the boot related switches (SW1 on the board overview picture):
6 GPIO mapping[edit]
6.1 GPIO expansion connector[edit]

- ↑ 1.01.11.21.3 The SAI2 is shared between the audio codec and the GPIO expansion connector. By default, the SAI2 is connected to the audio codec thanks to Solder Bridge SB13, SB14, SB15, and SB16: more details in the STM32MP157x-DKx discovery board user manual.
- ↑ 2.02.1 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.
6.2 Arduino Uno connector[edit]
The pins of the Arduino Uno connector are described in the following table:

6.3 User buttons and LEDs[edit]
The GPIO assignments for the user buttons and LEDs are described in the following table. Refer to LEDs and buttons on STM32 MPU boards article to get information on the functional mapping for each one.
LED color and label | Button label | GPIO |
---|---|---|
Green LD5 (*) | USER1 (*) | PA14 |
Red LD6 (*) | USER2 (*) | PA13 |
Orange LD7 | - | PH7 |
Blue LD8 | - | PD11 |
![]() |
(*) Both a LED and a button are connected to the same GPIO, with inverted logic for the LED control (so the LED is switched on when the GPIO output is set to low). |
