5.2. Preparing the USB serial link for flashing[edit | edit source]
It is recommended to use the USB (in DFU mode) for flashing rather than the UART, which is too slow.
Below indications on how to install the USB in DFU mode under Linux and Windows OS, respectively.
- For Linux host PC or Windows host PC with VMWare:
The libusb1.0 package (including USB DFU mode) must be installed to be able to connect to the board via the USB port. This is achieved by typing the following command from the host PC terminal:
PC $> sudo apt-get install libusb-1.0-0
To allow STM32CubeProgrammer to access the USB port through low-level commands, proceed as follows:
PC $> cd <your STM32CubeProgrammer install directory>/Drivers/rules
PC $> sudo cp *.* /etc/udev/rules.d/
- For Windows host PC:
Run the “STM32 Bootloader.bat” file to install the STM32CubeProgrammer DFU driver and activate the STM32 microprocessor device in USB DFU mode. This driver (installed by STM32 Bootloader.bat) is provided within the STM32CubeProgrammer release package. It is located in the DFU driver folder, \Drivers\DFU_Driver.
In case of issue, refer to How to proceed when the DFU driver installation fails on Windows host PC.
To validate the installation, the DFU driver functionality can be verified by following the FAQ instructions provided in how to check if the DFU driver is functional.
6. Downloading the image and flashing it on the board[edit | edit source]
6.1. Image download[edit | edit source]

6.2. Image flashing[edit | edit source]
The STM32CubeProgrammer tool is used to flash the STM32MP157x-DKx Discovery kit with the downloaded image.
The microSD card, provided in the box, is used as the Flash device: see the STM32MP15 Flash mapping article if you want to know more about the supported Flash memory technologies, and the Flash partitions.
As explained in the boot chain overview, the trusted boot chain is the default solution delivered by STMicroelectronics. Thus, the steps below use the image for the trusted boot chain.
Let's flash the downloaded image on the microSD card:
- Set the boot switches (1) to the off position
- Connect the USB Type-C™ (OTG) port (2) to the host PC that contains the downloaded image
- Insert the delivered microSD card into the dedicated slot (3)
- Connect the delivered power supply to the USB Type-C™ port (4)
- Press the reset button (5) to reset the board
- Go to the Starter Package directory that contains the binaries and the Flash layout files
PC $> cd <Starter Package installation directory>/unknown revision/images/stm32mp1
If you have followed the the proposition to organize the working directory, the command is PC $> cd Starter-Package/unknown revision/images/stm32mp1
|
The commands below are for a Linux host PC; however, they are similar for a Windows host PC except that STM32_Programmer_CLI is replaced by STM32_Programmer_CLI.exe. |
- Check that the STM32CubeProgrammer tool is installed and accessible; if not, go to the installation procedure (installing the tools)
PC $> STM32_Programmer_CLI --h
-------------------------------------------------------------------
STM32CubeProgrammer <tool version>
-------------------------------------------------------------------
- Get the device port location for the USB link
PC $> STM32_Programmer_CLI -l usb
-------------------------------------------------------------------

7. Booting the board[edit | edit source]
Now that the image is flashed on the STM32MP157x-DKx Discovery kit, let's finalize the system configuration:
- Step 1: check the configuration of the switches
- The figure below shows the position of the boot switches in order to boot from the microSD card.
- Step 2: (optional) connect a USB keyboard and/or a USB mouse (not provided) using the USB type A ports (3 and 4)
- Step 3: (optional) connect an Ethernet cable (not provided) to the dedicated connector (7)
- Step 4: check that the microSD card is inserted into the dedicated slot (2)
- Step 5: connect the provided power supply (5 V, 3 A) to the USB type C connector (8)
- Step 6: (optional) connect the ST-LINK/V2-1 USB micro-B port (5) to a host PC that runs a Terminal program with ST-LINK/V2-1 virtual port (e.g. Minicom on Ubuntu Linux PC or Tera Term on Windows PC)
- install and configure a remote Terminal program onto your host PC
- Step 7: (optional) connect a HDMI monitor (or TV) to the HDMI connector. This option is particularly useful for the STM32MP157A-DK1 and STM32MP157D-DK1 Discovery kits that do not include any DSI display daughterboard
- Step 8: press the reset button (6) to reset the board
The board boots and the system will be available after few seconds.
8. Checking the boot sequence[edit | edit source]
Assuming you have performed the optional step 6 above, the information (coming successively from the U-Boot and the Linux operating system that is booting on the board), should be displayed on the host PC Terminal.
|
|
The information displayed below might differ from that on your own application, and should just be considered an example. |
In parallel, a U-Boot splash screen picture is displayed on the DSI display (if one is connected to the board).
A user space graphical boot splash screen (PSplash) picture is then briefly displayed on the HDMI monitor if one is connected to the board, or otherwise on the DSI display (if one is connected to the board).
When the boot process is complete, the launcher application is shown on the HDMI monitor if one is connected to the board, or otherwise on the DSI display (if one is connected to the board).
More detail about this launcher application in GTK demo launcher page.
9. Mouse, keyboard and Ethernet hot-plugs[edit | edit source]
Let's assume that the optional step 2 and step 3 were not achieved when setting up the system above.
When connecting a USB mouse, the following information is displayed by the Terminal program:
[ 926.786326] usb 2-1.1: new low-speed USB device number 3 using ehci-platform
[ 926.961413] input: Logitech Optical USB Mouse as /devices/platform/soc/5800d000.usbh-ehci/usb2/2-1/2-1.1/2-1.1:1.0/0003:046D:C016.0001/input/input2

When connecting a USB keyboard, the following information is displayed by the Terminal program:
[ 1009.026567] usb 2-1.3: new low-speed USB device number 4 using ehci-platform
[ 1009.193990] input: Dell Dell USB Keyboard as /devices/platform/soc/5800d000.usbh-ehci/usb2/2-1/2-1.3/2-1.3:1.0/0003:413C:2003.0002/input/input3

When connecting an Ethernet cable, the following information is displayed by the Terminal program:
[ 1215.356377] stm32-dwmac 5800a000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx [ 1215.363377] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 1215.391068] Link is Up - 1000/Half
10. Remote and local Terminal programs[edit | edit source]
As already explained in the step 6 above, a remote Terminal program can be installed and configured on your host PC in order to communicate with the board through a serial link or an Ethernet link: see How to get Terminal.
The remote Terminal on your host PC can be used to enter command lines, as shown below with the ifconfig command to query the network interface parameters:
A local Terminal program can be launched directly on the board. Click on the small icon at the top left corner of the display (see the red arrow on the figure below):
Then the on-board Wayland Terminal can be used to directly enter command lines as shown below, still with the ip addr command to query the network interface parameters:
Consequently, unless an explicit restriction is mentioned, command lines can be run from both Terminals.
Note: in this article, any command executed on the board (through the remote Terminal or the Wayland Terminal) starts with Board $>, while any command executed on the host PC starts with PC $>.
11. Executing basic commands[edit | edit source]
