Once you set the switches, you can apply the following for booting from an SD card.

1. Downloading the Debian image

Download the Debian image by running the following command on your Linux/Windows PC:


2. Writing the image to the SD card

Use the following commands for writing the image to an SD card:

xz -dc imx8mp-sdhc-debian-ff28bac.img.xz | sudo dd of=/dev/sdX bs=4k conv=fdatasync status=progress

Note: Plug a micro SD into your Linux PC, the following assumes that the micro SD is added as /dev/sdX and all it’s partitions are unmounted.

3. SD card insertion

Please Insert the SD card into your device.

4. Power connection

Connect your power adaptor to the DC jack, and then connect the adaptor to mains supply.

2. Install the wpa_supplicant package:

3. Edit network interfaces file :

At the bottom of the file, add the following lines to allow wlan as a network connection:

4. Create a configuration file with the relevant ssid:

5. Make sure it works:

Restart your device and it should connect to the wireless network. If it doesn't, repeat above steps or get help from an adult.


1. For showing all Bluetooth devices, run the following:

2. Choose a device, and turn it on:

3. Set up the Bluetooth name:

4. Make your Bluetooth detectable by other devices:

5. If you want to connect to other devices:

  • Start by scanning for other Bluetooth devices:

  • Choose a MAC address and connect :

  • You can check the communication between the devices by writing :

GPIO Pins Control

In order to be able to control the GPIO pins, please refer to GPIO Pins Control - HummingBoard Pulse/Mate & i.MX8M Plus SOM

Please Note

Cellular Modem

The cellular modem is a more fully featured extension of which contains a cellular module with additional hardware interfaces and a SIM card slot.

You can connect your cellular modem to the mPCIe, and insert a SIM card.


For testing you serial peripheral interface - SPI, please see this documentation SPI from Linux with spidev.


First, you need to check that the required device is the default one by run:

If the sysdefault:CARD doesn’t set to wm8904 like this example

Then you can play sound with choosing the device who set to wm8904 and generate audio, in the above situation the device is hw:CARD=wm8904audio so the test will work as this:

  • NOTE: the “ -c “ flag used to set the number of the channels that you have in your audio output device, in my example I have 2 channels.

If the sysdefault:CARD=wm8904 you can test with this command:

GUI On Debian

There is an option with the Debian image, up to the user, to work with a GUI like Weston, GNOME and etc.
For applying this option do the following steps:

First, connect your device to a screen using the working output (HDMI / uHDMI).

For working with Weston GUI:

  1. Install the Weston package.

  2. Make a directory for the output of the Weston GUI.

  3. Give permissions to this directory.

  4. Set the XDG_RUNTIME_DIR env param to your directory.

  5. Run Weston.


For working with GNOME GUI on top of Xorg:

  1. Install Xorg.

  2. Install your desired gnome.

    NOTE: ‘gnome-session’ is an example of gnome that we can work with, you can replace the ‘session' with another GNOME extention.

  3. Start your GNOME GUI.

    • For logging in you need a user on your device to log into it. You can create one before step 3 by this command (replace the ‘username’ with name that you want) :

    • You can jump between GUIs that you install (like gnome-session) by the setting button that locates in the down right corner of the home screen.
