STM32MP15 Evaluation boards - starting for the first time


This article aims to present how to configure and start for the first time an STM32MP157x-EV1 Evaluation board that has just been flashed. It is valid both for the STM32MP157A-EV1 and STM32MP157C-EV1 Evaluation boards: the part numbers are specified in the STM32MP15 microprocessor part numbers article.

To start efficiently the board, it's recommended to go through the Starter Package article relative to your board: Category:Starter Package


Now that the image is flashed on the STM32MP157x-EV1 Evaluation board, let's finalize the system configuration:

  • Step 1: check the configuration of the switches and jumpers:
    • The boot related switches must be configured so that the device (e.g. microSD card ) on which the image has been flashed is selected as boot source.
    • The jumpers related to the UART4 of the STM32MP15 microprocessor device must be set so that UART4 is used by the ST-LINK/V2-1 controller (7)
The figure below shows the boot switches for the recommended boot from microSD card.

  • Step 2: (optionally) connect a USB keyboard and/or a USB mouse (not provided) using the USB type-A ports (10 and 11).
  • Step 3: (optionally) connect an Ethernet cable (not provided) to the dedicated connector (13).

  • Step 4: if the Flash device is a microSD card, check that it is inserted into the dedicated slot (5).
  • Step 5: connect the delivered power supply (5V, 3A) to the power connector (6) of the MB1263 daughterboard. Check that the display board (MB1230) is well connected. In this case, the 2 green LEDs (8) are switched on.
  • Step 6: (optionally) install and configure a remote Terminal program (e.g. Minicom on Ubuntu Linux PC or Tera Term on Windows PC) onto your host PC, and connect
    • either the ST-LINK/V2-1 USB micro-B port (7) to a host PC that runs a Terminal program with ST-LINK/V2-1 virtual port (recommended method)
    • or the RS232 UART4 connector (12) to the host PC that runs a Terminal program with COM1 port.
      • the ST-LINK/V2-1 USB micro-B port (7) and the RS232 UART4 connector (12) cannot be used simultaneously: see how to set the JP4 and JP5 jumpers to select one of the two configurations
  • Step 7: press the reset button (9) to reset the board

The board boots and the system will be available after few seconds.

Flash memory shortened to gain space in titles, tables and block diagrams

Flash memories combine high density and cost effectiveness of EPROMs with the electrical erasability of EEPROMs. For this reason, the Flash memory market is one of the most exciting areas of the semiconductor industry today and new applications requiring in system reprogramming, such as cellular telephones, automotive engine management systems, hard disk drives, PC BIOS software for Plug & Play, digital TV, set top boxes, fax and other modems, PC cards and multimedia CD-ROMs, offer the prospect of very high volume demand.
