Attached is the link to the image I used: https://pan.baidu.com/s/1DFJVej43-JWJVke37aW82A
Extraction code: xfjs, you can also go to Orange Pie official download
3. Serial port login system
-
Power supply: TypeC port, which needs to be plugged into a 5V/2A or 5V/3A power adapter, especially when the development board is connected to multiple peripheral modules. Normally, a computer can be used for USB power supply, provided that multiple peripheral modules are not connected.
-
Log in:
-
Use USB to TTL module, use MobaXterm which is free and easy to use. MobaXterm link: https://pan.baidu.com/s/1s8-c5One5odvBhhpjcRpjw
Extraction code: xfjs -
USB to TTL connection with Orange Pie:
a. The GND of the USB to TTL module is connected to the GND of the development board.
b. The RX of the USB to TTL module is connected to the TX of the development board
. c. The TX of the USB to TTL module is connected to the RX of the development board.
-
Also remember to install the driver for the USB to TTL converter tool. I use ch340.

Network Configuration:
Command to scan surrounding WIFI hotspots nmcli dev wifi
Command to access the network nmcli dev wifi connect Redmi_3DB4 password 123456789
Check the IP address ip addr show wlan0 ifconfig can also be used
4.SSH login system
- The prerequisite is to access the network and obtain the board IP address, and the system has
an SSH server. This image comes with an SSH server, so you can log in through mobaXterm.
5. Modify the log output by the kernel
- The official image blocks many logs. You can change the output level by modifying the orangepiEnv.txt configuration file. In this way, we can see the complete log through the serial port when booting, which is convenient for us to start and check faults sometimes.
sudo vi orangepiEnv.txt
