Evaluation boards with STM32MP157 MPUs
Introduction
The STM32MP157C-EV1 and STM32MP157A-EV1 Evaluation boards are designed as complete demonstration and
development platforms for STMicroelectronics Arm®-based dual -A7 32 bits and Cortex®-M4 32 bits MPUs in the STM32MP1
Series. They leverage the capabilities of STM32MP1 Series microprocessors for the user to develop applications, using STM32
MPU OpenSTLinux Distribution software for the main processor, and STM32CubeMP1 software for the co-processor. They
include an ST-LINK embedded debug tool, LEDs, push-buttons, one joystick, 1-Gbps Ethernet, CAN FD, one USB OTG MicroAB connector, four USB Host Type-A connectors, LCD display with touch panel, camera, stereo headset jack with analog
microphone input, four digital microphones, one SPDIF Rx/Tx, Smartcard, microSD™ card, and eMMC, NOR and NAND Flash
memories.
STM32MP157x-EV1, shown in Figure 1 and Figure 2, is used as the reference design for user application development,
although it is not considered as final application.
To expand the functionality of the STM32MP157C-EV1 and STM32MP157A-EV1 Evaluation boards, two GPIO expansion
connectors are also available for motor control and Raspberry Pi® shields.
An ST-LINK/V2-1 is integrated on the board, as embedded in-circuit debugger and programmer for the STM32 MPU and the
USB Virtual COM port bridge.

Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference
design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will
be liable for any customer usage of these engineering sample tools as reference design or in production.
“E” or “ES” marking examples of location:
• On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the STM32
datasheet “Package information” paragraph at the www.st.com website).
• Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
This board features a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number
and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.

Board function STLINK STM32 pin
As current consumption of the EVAL exceeds permissible current on USB, it is not possible to power the boards
through the STLINK-V2.1 USB. To use the STLINK-V2.1 for programming and debugging, it is mandatory to
power the board first using the 5V power supply, then connect the STLINK-V2.1 USB cable to the PC. Proceeding
this way the USB enumeration succeed thanks to the external power source.
The user must respect the following power sequence procedure:
1. Check that MB1263/JP1 is OFF, MB1263/JP4 [2-3] and JP5 [2-3] are ON to connect UART4 as STLINK
VCP.
2. Connect the 5 V power source, MB1263/LD1 LED turns green, MB1263/LD6 flashes red.
3. Connect the PC to USB connector MB1263/CN4, MB1263/LD6 is red and becomes green once the
connection with the STLINK is established.
6.7.1 Drivers
Before connecting STM32MP157x-EV1 to a Windows (XP, 7, 8 10) PC via USB, a driver for ST-LINK/V2-1 must
be installed. It may be downloaded from www.st.com.
In case the STM32MP157x-EV1 Evaluation board is connected to the PC before installing the driver, the Windows
device manager may report some USB devices found on STM32MP157x-EV1as “Unknown”. To recover from this
situation, after installing the dedicated driver downloaded from www.st.com, the association of “Unknown” USB
UM2535 - Rev 1
page 16/55
Page 17
UM2535
ETM TRACE Mictor-38 connector
devices found on STM32MP157x-EV1 to this dedicated driver must be updated in the device manager manually.
It is recommended to proceed using USB Composite Device line, as shown in Figure 9.
Figure 9. USB composite device
6.7.2 ST-LINK/V2-1 firmware upgrade
For its own operation, ST-LINK/V2-1 employs a dedicated MCU with Flash memory. Its firmware determines STLINK/V2-1 functionality and performance. The firmware may evolve during the life span of STM32MP157x-EV1 to
include new functionality, fix bugs or support new target microcontroller families. It is therefore recommended to
keep ST-LINK/V2-1 firmware up to date. The latest version is available from www.st.com.
6.8 ETM TRACE Mictor-38 connector
The Mictor-38 connector MB1262/U10 may output trace signals used for debug, as well as JTAG signals.

6.24 ADC/DAC
The STM32MP157x-EV1 provides some on-board analog-to-digital converters ADC and digital-to-analog
converters DAC:
• 2x ADC/DAC
• 2x Fast ADC
• 1x Slow ADC
6.24.1 ADC/DAC IO interface
The STM32MP157xAA3 port PA4 may be configured to operate either as ADC input or as DAC output. PA4 is
routed to two-way headers MB1263/JP11, to fetch signals to or from MB1263/JP11, or grounded it by fitting a
jumper into MB1263/JP11. Same situation for PA5 and its related MB1263/JP10 header.
Parameters of the ADC/DAC low-pass filters formed with MB1263/R24, C31, R19 for PA4 and MB1263/R25, C32,
R20 for PA5 may be modified by replacing these components according to application requirements (Default
configuration is: R24/R19/R25/R20=0 Ohm, C31/C32 not fitted).
UM2535
ADC/DAC
6.24.2 Fast ADC
ANA0 may be configured as a fast ADC channel routed to MB1263/JP8. MB1263/SB6, closed by default, should
be opened.
ANA1 may be configured as a fast ADC channel routed to MB1263/JP9. MB1263/SB7, closed by default, must be
opened.
Parameters of the low-pass filters formed with MB1263/R22, C29, and R17 for ANA0 and MB1263/R23, C30 and
R18 for ANA1 may be modified by replacing these components according to application requirements (Default
configuration is: R22/R17/R23/R18=0 Ohm, C29/C30 not fitted).
6.24.3 Slow ADC
The port PF12 may be configured as slow ADC channel, routed to MB1263/JP7. MB1263/SB5, closed by default,
must be opened.
Parameters of the low-pass filters formed with MB1263/R21, C28, and R16 may be modified to application
requirements (Default configuration is R21/R16=0 Ohm, C28 not fitted).
The VREF+ terminal of STM32MP157xAA3 is used as reference voltage for both ADC and DAC. By default, it is
connected on board to VDDA through MB1263/R96, which may be removed to apply directly an external voltage
to VREF+ for specific purposes.
