Description

The STM32MP257F-EV1 Evaluation board is designed as a complete demonstration and development platform for the STMicroelectronics STM32MP257FAI3 based on the Arm® Cortex® A35 and M33.
The product leverages the capabilities of STM32MP2 series microprocessors to allow users to develop applications using STM32 MPU OpenSTLinux distribution software for the main processor (Arm®dual core

Cortex®‑A35) and STM32CubeMP2 software for the coprocessor (Arm® Cortex®‑M33).
The product includes an ST-LINK embedded debug tool, LEDs, push-buttons, three 1 Gbit/s Ethernet, two
CAN FD, one USB Type-C® DRD connector, two USB Host Type-A connectors, one mini PCIE connector, one LCD LVDS display connector, one LCD DSI connector, one camera connector, microSD™ card, eMMC, and NOR flash memory. To expand the functionality of the STM32MP257F-EV1 Evaluation board, one GPIO expansion connector is also available for Raspberry Pi® shields, and one mikroBUS™ expansion connector.

Ordering information
To order the STM32MP257F-EV1 Evaluation board, refer to Table 1. For a detailed description, refer to its user manual on the product web page. Additional information is available from the datasheet and reference manual of the target STM32.

Subsequently called main board in the rest of the documentation.

Product marking
The stickers located on the top or bottom side of all PCBs provide product information

• First sticker: product order code and product identification, generally placed on the main board featuring the target device.
  Example

• Second sticker: board reference with revision and serial number, available on each PCB. Example:

On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx- Variant-yzz”, where “MBxxxx” is the board reference, “Variant” (optional) identifies the mounting variant when several exist, “y” is the PCB revision, and “zz” is the assembly revision, for example B01. The second line shows the board serial number used for traceability.

Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not responsible for any consequences resulting from such use. In no event will ST be liable for the customer using any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision to use these engineering samples to run a qualification activity.

“ES” or “E” marking examples of location

• On the targeted STM32 that is soldered on the board (for an 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.

Some boards feature 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.

To use the same commercial stack in their applications, the developers might need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.

Codification
The meaning of the codification is explained in Table 2.
