¶ Desktop
Use the following commands to check whether the system boots to the graphical target and whether the display manager is running.
systemctl get-default
systemctl is-active display-manager
loginctl list-sessionsTest result:
graphical.target
active¶ Debug UART
¶ SSH
-
Prepare a network cable and a router.
-
Connect the BPI-CM7IO Ethernet port and the PC to the same LAN.
-
Check the board IP address from the router management page, or run the following command from a local terminal on the board.
ip -brief address show eth0 hostname -I -
Check the SSH service status on the board.
systemctl is-active ssh -
Open a terminal on the PC and connect to the board. Replace
<board-ip>with the actual address assigned by the router.ssh pi@<board-ip> -
After login, use the following commands to confirm the remote user, board name, and kernel.
whoami hostnamectl --static uname -r
Test result:
SSH service: active
Remote login: successful
User: pi
Hostname: bpi-cm7
Kernel: 5.4.125-legacy-sunxi64¶ NoMachine Remote Desktop
¶ armbian-config
Check whether armbian-config is installed.
command -v armbian-configEnter the Armbian configuration utility with the following command.
sudo armbian-configTest result:
/usr/bin/armbian-config¶ WiFi
Use the nmcli command to list network devices and scan Wi-Fi access points.
nmcli device # List devices
nmcli device wifi list # List available Wi-Fi access points
rfkill list # Check whether Wi-Fi is blockedUse the following commands to connect, disconnect, or create a Wi-Fi hotspot.
nmcli device wifi connect [SSID] password [PASSWORD]
nmcli connection up [SSID]
nmcli device disconnect [device name]
nmcli device wifi hotspot con-name [NAME] ifname [device name] ssid [SSID] password [PASSWORD]
nmcli connection show
nmcli connection down [NAME]
nmcli connection up [NAME]
nmcli connection delete [SSID]
nmcli radio wifi off
nmcli radio wifi onTest result:
Interface: wlan0
rfkill soft blocked: no
rfkill hard blocked: no
Wi-Fi scan: successful¶ Set static IP, DNS
¶ Network time synchronization
Chrony is used in the tested image for network time synchronization.
Use the following commands to check the system clock, synchronization status, Chrony service, and time sources.
timedatectl status
systemctl status chrony
chronyc tracking
chronyc sources -v
dateUse the following commands to manage the Chrony service.
sudo systemctl start chrony
sudo systemctl enable chrony
sudo systemctl restart chronyUse the following commands to list or change the time zone.
timedatectl list-timezones
sudo timedatectl set-timezone Asia/ShanghaiTest result:
System clock synchronized: yes
NTP service: active
Chrony service: active
Time zone during test: Etc/UTC¶ View hardware temperature
Use the following commands to identify the four thermal zones.
cat /sys/class/thermal/thermal_zone0/type
cat /sys/class/thermal/thermal_zone1/type
cat /sys/class/thermal/thermal_zone2/type
cat /sys/class/thermal/thermal_zone3/typeUse the following commands to read the temperatures.
cat /sys/class/thermal/thermal_zone0/temp
cat /sys/class/thermal/thermal_zone1/temp
cat /sys/class/thermal/thermal_zone2/temp
cat /sys/class/thermal/thermal_zone3/tempDivide each returned value by 1000 to obtain the temperature in degrees Celsius.
Test result:
cpu_thermal_zone: 50.2 °C
ddr_thermal_zone: 51.4 °C
gpu_thermal_zone: 53.4 °C
ve_thermal_zone: 50.8 °C¶ Use USB disk
¶ Use Audio Devices
¶ HDMI audio
¶ 3.5mm audio jack
¶ Terminal command to play audio files
Use the following command to list the audio playback devices.
aplay -l # List playback devicesTest result:

¶ Use Bluetooth
¶ Use IR Receiver
¶ Transfer files
¶ scp
SCP uses the SSH protocol to copy files securely between the PC and BPI-CM7. Make sure the PC and board are connected to the same LAN and that SSH login works first.
The SCP command format is:
scp [options] file_source file_targetUse -r to copy a directory recursively.
Copy a local file from the PC to BPI-CM7:
scp local-file pi@<board-ip>:/home/pi/Copy a file from BPI-CM7 to the PC:
scp pi@<board-ip>:/home/pi/remote-file ./Test result:
Upload to /tmp: successful
Remote file size and SHA-256 verification: successful
Temporary test file removal: successful¶ mobaxterm
