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

1 Article purpose[edit]

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

↑ 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]

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]

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]

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:

Engineering boot	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]

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]

6.1 Motor control connector[edit]

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 board user manual.

Warning

The pin 1 position (upper left) on this figure is the opposite compared to the board (bottom right)

↑ ^1.0^1.1 The I2C5 is shared between the I2C EXT connector and the GPIO expansion connector. By default, the I2C5 is connected to the I2C EXT connector thanks to Solder Bridges: more details in the STM32MP157x-EV1 evaluation board user manual.
↑ ^2.0^2.1^2.2^2.3 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 Bridges: more details in the STM32MP157x-EV1 evaluation board user manual.

6.3 JTAG connector[edit]

6.4 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.

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

(*) 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).

==Board connection==
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|board overview]], other connectors are available for this board (for example CAN).
{{:STM32MP157x-EV1 - board connections}}

==Switches and jumpers==
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.
[[File:MB1263_switches_jumpers.png|thumb|upright=4|center|link=|MB1263 zoom on some switches and jumpers]]

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

The boot related switches ([[#MB1263-SW1|SW1]] on the board overview picture) must be configured as illustrated by one of the following pictures:

|}

===UART4 related jumpers: RS232 or ST-LINK/V2-1?===
The UART4 is shared exclusively between 2 connectors:
* RS232, D-type, 9-pin connector ([[#MB1262-CN12|CN12]] on the board overview picture),  dedicated to communication through RS232, 
* USB micro-B (ST-LINK/V2-1) ([[#MB1263-CN4|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:
{| class="st-table"
| [[File:STM32MP157x-EV1_JP4_JP5_UART4_on_DB9_CN12.png|thumb|center|link=|UART4 is connected to the RS232, D-type, 9-pins [[#MB1262-CN12|CN12]] connector]] || [[File:STM32MP157x-EV1_JP4_JP5_UART4_on_ST-Link_V2-1_CN4.png|thumb|center|link=|UART4 is connected to the USB micro-B ST-LINK/V2-1 [[#MB1263-CN4|CN4]] connector]]
|}

==GPIO mapping==

===Motor control connector===
The pins of the motor control connector ([[#MB1262-CN22|CN22]] on the board overview picture) are described in the following table.<br>

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 [[STM32MP15 resources#UM2535|'''STM32MP157x-EV1 evaluation board user manual''']].

[1] LD1 (MB1262): flashes green when Ethernet connection established

[2] LD2 (MB1262): turns green when USB OTG connection established

[3] LD3 (MB1262): turns red if USB Type-A connection established

[User_LEDs-4] 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

[5] LD1 (MB1263): turns green if power connection established

[6] LD6 (MB1263): flashes red if ST-LINK/V2-1 connection not established, else green

[I2C5-7] 1.0^1.1 The I2C5 is shared between the I2C EXT connector and the GPIO expansion connector. By default, the I2C5 is connected to the I2C EXT connector thanks to Solder Bridges: more details in the STM32MP157x-EV1 evaluation board user manual.

[SAI2-8] 2.0^2.1^2.2^2.3 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 Bridges: more details in the STM32MP157x-EV1 evaluation board user manual.
