Subpart - STM32MP15 - Starter Package


1 Article purpose[edit]

This article gathers the information that applies to any STM32MP15 board.

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

That's the reason why the steps 2, 3 and 6 referenced in this article depend on the considered board:


2 Checking the boot sequence[edit]

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.

Info.png 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).DSI U-Boot splash screen.png

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).DSI user splash screen.png


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.

3 Mouse, keyboard and Ethernet hot-plugs[edit]

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
[  926.975098] hid-generic 0003:046D:C016.0001: input: USB HID v1.10 Mouse [Logitech Optical USB Mouse] on usb-5800d000.usbh-ehci-1.1/input0


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
[ 1009.280101] hid-generic 0003:413C:2003.0002: input: USB HID v1.10 Keyboard [Dell Dell USB Keyboard] on usb-5800d000.usbh-ehci-1.3/input0


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

4 Remote and local Terminal programs[edit]

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:

Example of command (ifconfig) executed on the remote Terminal program


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):

Wayland Terminal program


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:

Example of command (ip addr) executed on the Wayland Terminal program


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 $>.

5 Executing basic commands[edit]

Info.png The outputs of the commands executed below are examples; the outputs obtained might differ.

5.1 Having a look at the OpenSTLinux directory structure[edit]

The directory structure and directory contents in the OpenSTLinux distribution is standard. Some details are available in the OpenSTLinux directory structure article.

5.2 Identifying the software running on board[edit]

Info.png Obviously, what you obtain might differ from what is displayed on the Output example column.

5.3 Configuration tips[edit]

5.4 Getting board IP address[edit]

Prerequisite: your board is connected to your local network through the Ethernet connector (see step 3).

Board $> ip addr show eth0                                                                           
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet xx.xx.xx.xx/xx brd xx.xx.xx.xx scope global dynamic eth0
       valid_lft 159045sec preferred_lft 159045sec
    inet6 xxxx::xx:xx:xx:xx/xx scope link 
       valid_lft forever preferred_lft forever
  • Get the IP address of your board with the ifconfig Linux command line (a deprecated but well-known command):
Board $> ifconfig eth0
eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:xx.xx.xx.xx  Bcast:xx.xx.xx.xx  Mask:255.255.252.0
          inet6 addr: xxxx::xx:xx:xx:xx/xx Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2619 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1311 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:353250 (344.9 KiB)  TX bytes:118305 (115.5 KiB)
          Interrupt:247
