¶ Development
¶ Prepare
-
12V/3A power adapter(The voltage range is between 11 and 13 volts. Using a 12V power adapter is the most suitable option.)
-
Using your USB-Serial cable(3.3V TTL,Baud=115200) Connect to debug console on BPI-SM9
-
One TF card(If you want to use the FT card for system startup)
-
One Type-C cable (for upgrade programming)

¶ Accessories
¶ SD card burn image
| Please pay attention to whether the TF card clips on the board are correctly positioned. please see: TF card detection and GPIO selection |
-
First, download the corresponding SD card burning package, and then copy the files in it to the SD card.
-
Insert the card into the BPI-SM9 and power it on to start.
-
Finally, it will automatically be updated and burned.
¶ OTG typeC burn image
-
Please download and unzip the tool flashing package "usb_tool".
-
Double-click on CviUsbInstallDriver.exe to install the driver for your PC.
-
Open the Windows Command Prompt in the directory of the usb_dl.exe file and enter:
./usb_dl.exe -c cv186x -i usb\
-
When the above interface appears, simply reinsert and remove the OTG type C interface to proceed with the burning process.

¶ CAN
| blue ：CAN_H Green： CAN_L |
Connection interface
CAN communication can be easily implemented using the scripts in the SM9 folder.
¶ eth interface
| The eth0 interface is located near the type-c interface.The other one is the eth1 interface. |
| The default static IP address for the eth1 network interface mirror is 192.168.150.1.You can modify the IP address in /etc/netplan/01-netcfg.yaml |
Connect the network port to the computer using a network cable.
¶ eth0
-
Use the command to set the IP address of eth0.
sudo ifconfig eth0 xxx(xxx is ip)iperf3 test speed
¶ M.2 KeyE
Supported network cards: Intel RTL8822CE
¶ WiFi STA
| You can modify the WiFi username and password you want to connect to in /etc/wpa_supplicant.conf |
-
First, execute the command to add the WiFi driver.
sudo insmod /mnt/system/ko/3rd/xxx.ko //xxx is the network cards name -
Connect to WiFi using a script
./wifista.sh
¶ WiFi AP
| You can modify the WiFi username and password to be created in /etc/hostapd.conf |
If you have already loaded the driver in your system, you can directly execute the script to create a Wi-Fi network.
./wifiap.sh
¶ bluetooth
-
Load driver: sudo insmod /mnt/system/ko/3rd/rtk_btusb.ko
-
Verify driver functionality, use
hciconfigIf a Bluetooth node is present, the driver is functioning correctly.
-
Confirm Bluetooth service is running normally
-
Use BlueZ tools for communication
bluetoothctl //Enter Bluetooth debugging tool power on //Turn on Bluetooth power scan on //Scan for surrounding Bluetooth pair XX:XX:XX:XX:XX:XX //Connect via Bluetooth (The following is MAC address)
¶ RTC
Please install a CR1220 button battery in the SM9 before use.
-
View the current clock use the command:
sudo hwclock -r --show -
Set the clock:
sudo date -s "20xx-xx-xx 09:09:55" -
Synchronize to hardware clock:
sudo hwclock --systohc -
Power off and restart, then check the clock:
sudo hwclock -r --show -
It can be determined that the displayed time is an RTC clock.
¶ NVME
Connect NVMe to the M.2 SSD interface.Then you can use this hard drive.
¶ CAMERA
| They cannot be used simultaneously. |
¶ CAM1
| Near the JP7 |
If you are using a different MIPI camera, please uninstall the driver for that camera first:
rmmod /mnt/system/ko/v4l2_csi0_ov5647.ko
-
Switch I2C to csi2:
echo 8 > /proc/zkwl/gpio -
Install driver:
sudo insmod /mnt/system/ko/v4l2_csi2_ov5647.ko -
Create a video stream:
cd /opt/sophon/sophon-soc-libisp-dev_1.0.0/bin/sudo ./CviIspTool.sh -
Use your video software to pull the video stream from VLC.
¶ CAM2
| Near the 12V power port |
If you are using a different MIPI camera, please uninstall the driver for that camera first:
rmmod /mnt/system/ko/v4l2_csi2_ov5647.ko
-
Switch I2C to csi0:
echo 9 > /proc/zkwl/gpio -
Install driver:
sudo insmod /mnt/system/ko/v4l2_csi0_ov5647.ko -
Create video stream length
cd /opt/sophon/sophon-soc-libisp-dev_1.0.0/bin/sudo ./CviIspTool.sh -
. Use your video software to pull the video stream from VLC.
