CanBUS and RS485 Support

Initial Setup

HummingBoard CBi can use the CAN-Bus and RS485 only if booted with the appropriate device-tree. From U-Boot console, interrupt boot by pressing any key during the Hit any key to stop autoboot prompt. Then permanently choose the cbi device-tree variant:

Hit any key to stop autoboot:  0
=> setenv is_cbi 1
=> saveenv
=> reset

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

apt-get update 
apt-get upgrade 
reboot

CanBUS Enable

1. Download the compressed zip file:

sudo wget https://developer.solid-run.com/wp-content/uploads/2021/12/hb-cbi-dtbs-k5.10.zip -O /tmp/hb-cbi-dtbs-k5.10.zip

2. Unzip the file:

unzip -o /tmp/hb-cbi-dtbs-k5.10.zip -d /boot/dtbs/5.10.0-8-armmp/

3. Restart your device:

reboot

RS485 Enable

1. Add a support for rs485conf and compile an exec file by runnig the following:

git clone https://github.com/mniestroj/rs485conf.git
cd rs485conf
make

2. Copy the output of the exec file bu running:

cp rs485conf /usr/bin/

3. Add an execute permission to the file:

 chmod +x /usr/bin/rs485conf

Install to eMMC

• You can follow this document Install to eMMC to install debian to an eMMC device.

More Features

Internet

• 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.MX6 Debian .

Wi-fi

• 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
