Software Setup Cable setup and prerequisites
Here is what you will need to power up the board:
Linux or Windows PC
HummingBoard CBi with SOM
12V Power adapter (HummingBoard CBi has wide range input of 9V-36V, it is recommended to use 12V power adapter)
USB to UART cable
IP router or IP switch
Booting form an SD card
On the HummingBoard CBi it is possible to boot from different media.
For Booting from an SD card, jumpers need to be setup at J5005 as follows:
Once you setup the jumpers, you can apply the following for booting from an 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/IMX6/Debian/sr-imx6-debian-bullseye-20220712-cli-sdhc.img.xz 2. Writing the image to the SD card
Use the following commands for writing the image to an SD card:
xz -dc sr-imx6-debian-bullseye-20220712-cli-sdhc.img.xz | dd of=/dev/sdX bs=4M conv=fsync
Note: Plug a micro SD into your Linux PC, the following assumes that the 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. Serial connection
Please connect the UART cable to the pins on connector J25 as shown in the below picture, then you can refer to
Serial Connection for installing necessary serial connection software in Linux/Windows.
Once you installed the necessary serial connection software, please run the following:
setenv som_rev 'V15'; saveenv; boot
And you should be able to see the following:
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
=> reset Use the following commands in order to keep your system up-to-date: apt-get update
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:
1. Add a support for rs485conf and compile an exec file by runnig the following:
git clone https://github.com/mniestroj/rs485conf.git
Before you run the above, please install some helping commands by running:
apt-get install make gcc git
2. Copy the output of the exec file bu running:
3. Add an execute permission to the file:
chmod +x /usr/bin/rs485conf Install to eMMC More Features Internet apt-get update
An example for connecting to WiFi using wpa_supplicant:
1. To bring a WiFi interface up, run the following :
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
iface wlan0 inet dhcp
iface default inet dhcp
4. Create a configuration file with the relevant ssid:
cat <<EOF > /etc/wpa_supplicant/wpa_supplicant.conf
Check your personal ssids by running : ‘iw dev wlan0 scan’
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
2. Choose a device, and turn it on:
3. Set up the Bluetooth name:
hciconfig hci0 name 'SolidRun_Ble'
4. Make your Bluetooth detectable by other devices:
5. If you want to connect to other devices:
rfcomm connect 0 $MAC 10 &
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.
