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 
[1], STM32MP157D-EV1 
[2], STM32MP157C-EV1 [3] and STM32MP157F-EV1 [4] Evaluation boards: the part numbers are specified in the STM32MP15 microprocessor part numbers article.
2. Board assembly[edit | edit source]
The STM32MP157x-EV1 Evaluation boards packages (STM32MP157A-EV1 , STM32MP157D-EV1 , STM32MP157C-EV1 and STM32MP157F-EV1 ) include all the items listed below.
| Position | Description |
|---|---|
| 1 | MB1262 motherboard |
| 2 | MB1263 daughterboard |
| 3 | MB1230 DSI 720p display |
| 4 | MB1379 daughterboard camera (OmniVision OV5640 camera sensor) |
| 5 | microSD card |
| 6 | Power supply block (5V, 3A) |
The following figures explain how to assemble these different items to get the STM32MP157x-EV1 Evaluation boards.

Details about some LEDs:
- ↑ LD1 (MB1262): flashes green when Ethernet connection established
- ↑ LD2 (MB1262): turns green when USB OTG connection established
- ↑ LD3 (MB1262): turns red if USB Type-A connection established
- ↑ Jump up to: 4.0 4.1 4.2 4.3 LD2, LD3, LD4, LD5 (MB1263): 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
- ↑ LD1 (MB1263): turns green if power connection established
- ↑ LD6 (MB1263): flashes red if ST-LINK/V2-1 connection not established, else green
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.

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