Software Setup

Cable setup and prerequisites

Here is what you will need to power up and use the board:

• Linux or Windows PC

• HummingBoard Extended with RZ/G2L SOM (HummingBoard Extended & RZ/V2L SOM)

• 12V Power adapter (HummingBoard Extended has wide range input of 7V-36V, it is recommended to use 12V power adapter).

• Micro USB to USB for console, the HummingBoard Extended has an onboard FTDI chip.

• IP router or IP switch

• USB Disk and SD Card

Boot Select

Before powering up the board for the first time it is recommended to select the boot media. In order to configure the boot media, please refer to HummingBoard RZ/G2L Boot Select .

Booting from SD card

The following shows how to set the switches on the boot source selector:

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

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

   wget https://solid-run-images.sos-de-fra-1.exo.io/RZG2LC/Debian/sr-rzg2lc-debian-bullseye-8471270-cli-rzg2lc-hummingboard.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:

   xz -dc sr-rzg2lc-debian-bullseye-8471270-cli-rzg2lc-hummingboard.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:

   

• In order to be able to log in , please insert “debian” as a username and password as follows:

  

1. Final stages

The following stages need to be done in order to finalise the imaging:

1. Run fdisk /dev/mmcblk0 if using SD or eMMC.

2. Recreate the first partition by deleting it and then creating a new partition that starts at block 16384 and extends to the end of the drive (or less depending on your needs).

3. Write the new partition, when prompt about ‘Do you want to remove the signature?’ then answer with Yes.

4. Run resize2fs /dev/mmcblk0p1 if using SD Card or eMMC.

5. In this stage the root partition should be big enough to start populating it; but first update the RTC clock.

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

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

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

   apt-get update && apt-get upgrade -y

Please see below an example of resizing the filesystem :

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 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 

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

1. 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

1. Choose a device, and turn it on:

 hciconfig hci0 up

1. Set up the Bluetooth name:

hciconfig hci0 name 'SolidRun_Ble'

1. Make your Bluetooth detectable by other devices:

hciconfig hci0 piscan

1. 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 .
