Renesas RZ 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 RZ/G2LC 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 

To discover your wireless network interface name, see Network Interfaces.

1. Install the wpa_supplicant package:

$ apt-get install wpasupplicant 

1. 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

1. 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

Check your personal ssids by running : ‘iw dev wlan0 scan’

1. Make sure it works:

Restart your device and it should connect to the wireless network. You can check it by running the command $ iwconfig . 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
$ bluetoothctl

1. Turn the device on:

[bluetooth]# power on

1. Make your Bluetooth detectable by other devices:

[bluetooth]# discoverable on

1. If you want to connect to other devices:

• Start by scanning for other Bluetooth devices:

[bluetooth]# scan on

• Choose a MAC address and connect :

[bluetooth]# pair $MAC 

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

[bluetooth]# paired-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.

 $ sudo apt install modemmanager

2. Search for your modem location:

$ mmcli -L

3. Connect to your modem:

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

4. Enable the modem:

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

5. Scan for networks:

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

6. connect to 3gpp network:

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

7. Make sure the connection was created:

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

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

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.

sudo apt install weston

1. Set the XDG_RUNTIME_DIR env param.

cat << 'EOF' > /etc/profile.d/weston.sh
if test -z "$XDG_RUNTIME_DIR"; then
    export XDG_RUNTIME_DIR=/run/user/`id -u`
    if ! test -d "${XDG_RUNTIME_DIR}"; then
        # Make a directory for the output of the Weston GUI
        mkdir --parents "${XDG_RUNTIME_DIR}"
        chmod 0700 "${XDG_RUNTIME_DIR}"
    fi
fi
EOF

1. Restart the system

reboot

1. Start Weston (must be run from the Dissplay Terminal)

weston

Run the weston command from the Dissplay Terminal using keyboard (PHYSICAL TERMINAL not serial session or remote connection)

For working with GNOME GUI on top of Xorg:

1. Install Xorg.

$ sudo apt install xorg

1. Install your desired gnome.

$ 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.

$ 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) :

$ 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.
