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

   Code Block
   wget https://solid-run-images.sos-de-fra-1.exo.io/RZ/rzg2lc_build/20231122-6391518/rzg2lc-solidrun-sd-debian-6391518.img.xz

   • For more Debian releases, please visit Debian Releases for RZ/G2LC.

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

   Code Block
   xz -dc rzg2lc-solidrun-sd-debian-6391518.img.xz | dd of=/dev/sdX bs=4k conv=fdatasync

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

   • Note:Plug a micro SD into your Linux PC, the following assumes that the USB-Disk / 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.

5. Power On
   Hold on the On/Off Power button - SW1 (as shown in the figure below)

   

   • Note: The system should turn on by default when the power is connected (without pressing the button).

6. Serial Connection
   Please insert the micro USB into your device, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows.
   Once you installed the necessary serial connection software, you should be able to see the following:

...

• Enter as a “root” in the login “root” like in the above example and then you can move on to use the device.

...

The following stages need to be done in order to finalise the imaging from the computer after flashing it.

1. Run the following commands before the first boot:
   $ sudo umount /dev/sda2.
   $ sudo e2fsck -f /dev/sda2.
   $ sudo resize2fs /dev/sda2.
   $ sudo parted /dev/sda.
   $ (parted) resizepart 2.
   $ (parted) 15000 .

2. Boot your device.

3. Connect the RJ45 to your network with internet access (and DHCP server); and then run dhclient.

4. Update the RTC clock by running ntpdate pool.ntp.org and then hwclock -w.

5. Run apt-update commands below and then populate the root filesystem as you wish.

   Code Block
   $ apt-get update && apt-get upgrade -y

Please see below an example of resizing the filesystem :

...

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.

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

$ apt-get install bluez
hciconfig$ -a

...

bluetoothctl

2. Turn the device on:

[bluetooth]# hciconfigpower hci0 up

1. Set up the Bluetooth name:

hciconfig hci0 name 'SolidRun_Ble'

on

3. Make your Bluetooth detectable by other devices:

hciconfig hci0 piscan[bluetooth]# discoverable on

4. If you want to connect to other devices:

• Start by scanning for other Bluetooth devices:

hcitool[bluetooth]# scan on

• Choose a MAC address and connect :

rfcomm connect 0  $MAC 10 & [bluetooth]# pair $MAC 

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

l2ping[bluetooth]# -c 4  $MACpaired-devices

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.

• How to connect to the network:
  1. Install “modemmanager” package on your debian.

  Code Block
  $ sudo apt install modemmanager

  2. Search for your modem location:

  Code Block
  $ mmcli -L

  3. Connect to your modem:

  Code Block
  $ mmcli --modem=/your/modem/location

  4. Enable the modem:

  Code Block
  $ mmcli --modem=/your/modem/location -e

  5. Scan for networks:

  Code Block
  $ mmcli --modem=/your/modem/location --3gpp-scan

  6. connect to 3gpp network:

  Code Block
  $ mmcli --modem=/your/modem/location --3gpp-register-in-operator=<network ID>

  7. Make sure the connection was created:

  Code Block
  $ mmcli --modem=/your/modem/location

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