wget https://solid-run-images.sos-de-fra-1.exo.io/IMX8/imx8mp_build/build_date_20240806-rev_449b768/imx8mp-sdhc-debian-449b768.img.xz

• For more Debian releases, please visit Debian Release for i.MX8.

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-449b768.img.xz | sudo dd of=/dev/sdX bs=4k conv=fdatasync status=progress

• For more information, please visit Flashing an SD Card .

3. SD card insertion

Please Insert the SD card into your device.

4. Power connection

More Features

Internet

Connect an Ethernet cable to your HummingBoard Pulse (for internet access during boot-up).
Models HummingBoard with WiFi, can be connected via WiFi or wired Ethernet.

• Please check you Ethernet connection.

• Use the following commands in order to keep your system up-to-date:

apt-get update 
apt-get upgrade 
reboot

• For more detailed information, please refer to i.MX8M Debian .

WiFi

• You can connect to WiFi using any application, such as : connmanctl or wpa_spplicant.

An example for connecting to WiFi using wpa_supplicant:

1. To bring a WiFi interface up, run the following :

ifconfig wlan0 up 

2. Install the wpa_supplicant package:

apt-get install wpasupplicant 

3. Edit network interfaces file :

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

cat <<EOF > /etc/network/interfaces.d/wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

EOF

4. Create a configuration file with the relevant ssid:

cat <<EOF > /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/run/wpa_supplicant
update_config=1

network={
    ssid="MYSSID"
    psk="passphrase" 
}

EOF

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.

• For more information about using wpa_supplicant , you can refer to wpa_supplicant or wpa_supplicant.

Bluetooth

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

apt-get install bluez
hciconfig -a

2. Choose a device, and turn it on:

 hciconfig hci0 up

3. Set up the Bluetooth name:

hciconfig hci0 name 'SolidRun_Ble'

4. Make your Bluetooth detectable by other devices:

hciconfig hci0 piscan

5. If you want to connect to other devices:

• Start by scanning for other Bluetooth devices:

hcitool scan

• Choose a MAC address and connect :

rfcomm connect 0  $MAC 10 & 

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

l2ping -c 4  $MAC

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 some cellular modules to be connected, please refer to Cellular Modules .

SPI

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

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.

   Code Block
   $ sudo apt install weston

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

   Code Block
   $ mkdir /your/directory/location

3. Give permissions to this directory.

   Code Block
   $ chmod 0700 /your/directory/location

4. Set the XDG_RUNTIME_DIR env param to your directory.

   Code Block
   $ export XDG_RUNTIME_DIR=/your/directory/location

5. Run Weston.

   Code Block
   $ weston

    

For working with GNOME GUI on top of Xorg:

1. Install Xorg.

   Code Block
   $ sudo apt install xorg

2. Install your desired gnome.

   Code Block
   $ sudo apt install gnome-session

   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.

   Code Block
   $ sudo systemctl start gdm

   • 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) :

   Code Block
   $ sudo adduser username

   • 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.
