Applicable for STM32MP15x lines

This article provides an overview of STM32MP157x-EV1 Evaluation boards.

1. Article purpose[edit | edit source]

This article briefly describes:

  • How to assemble together the different elements provided in the commercial box
  • What are the different components present on the boards
  • How to connect the boards to external material
  • How to configure the board for boot
  • How to select RS232 UART or ST-LINK/V2-1 connectors
  • What are the configurations of the connectors pins

This article is valid for the STM32MP157A-EV1 Warning.png[1], STM32MP157D-EV1 More info green.png[2], STM32MP157C-EV1 Warning.png[3] and STM32MP157F-EV1 More info green.png[4] Evaluation boards: the part numbers are specified in the STM32MP15 microprocessor part numbers article.

4. Board connection[edit | edit source]

The connections shown in the picture below are the ones recommended to start with the STM32MP157x-EV1 Evaluation boards. As shown in the board overview, other connectors are available for this board (for example CAN).

5. Switches and jumpers[edit | edit source]

Most of default settings of the switches and jumpers shall be kept as set in the commercial box.

There are 3 main exceptions:

  • the jumpers related to UART4
  • the switches related to boot
  • the jumper JP1 that must be removed

The picture and sections below detail the main boot switches and the UART4 jumpers.

MB1263 zoom on some switches and jumpers

5.1. Boot related switches[edit | edit source]

The STM32MP157x-EV1 Evaluation boards can boot from different Flash devices (microSD, eMMC...); using the microSD card is recommended.

Boot modes
Boot mode Boot 2 Boot 1 Boot 0
Engineering boot 1 0 0
NOR 0 0 1
microSD card 1 0 1
eMMC 0 1 0
NAND 0 1 1
Forced USB boot
for flashing		 0 0 0

The boot related switches (SW1 on the board overview picture) must be configured as illustrated by one of the following pictures:

Boot from NOR
Boot from microSD card
Boot from eMMC
Boot from NAND
Forced USB boot for flashing

5.2. UART4 related jumpers: RS232 or ST-LINK/V2-1?[edit | edit source]

The UART4 is shared exclusively between 2 connectors:

  • RS232, D-type, 9-pin connector (CN12 on the board overview picture), dedicated to communication through RS232,
  • USB micro-B (ST-LINK/V2-1) (CN4 on the board overview picture), dedicated to the RS232 of ST-LINK/V2-1 controller

The connection is switched by setting JP4 and JP5 jumpers as shown in following pictures:

UART4 is connected to the RS232, D-type, 9-pins CN12 connector
UART4 is connected to the USB micro-B ST-LINK/V2-1 CN4 connector

6. GPIO mapping[edit | edit source]

6.1. Motor control connector[edit | edit source]

The pins of the motor control connector (CN22 on the board overview picture) are described in the following table.
Due to the sharing of some IOs by multiple peripherals, the motor control interface is not enabled by default, and the motor control cannot be operated simultaneously with the camera, audio codec, CAN and GPIO expansion (GPIO6, 7 and 12): more details (e.g. enabling the motor control interface) in the STM32MP157x-EV1 Evaluation boards user manuals.

6.4. User buttons and LEDs[edit | edit source]

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.

GPIO for user buttons and LEDs
LED color and label Button label GPIO
Green LD3 (*) USER1 (*) PA14
Red LD2 (*) USER2 (*) PA13
Orange LD4 - PD8
Blue LD5 - PD9
Warning white.png Warning
(*) 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).
