Chapter 3
Using Linux on your
Orange Pi
Learn about the Orange Pi Operating System.
O
range Pi Zero2 can run a wide range of Operating Systems like Ubuntu,
Debian, and Android 10, including server editions of Ubuntu and Debian.
In this chapter, we will learn some basic configurations like changing the screen
resolution, adjusting Linux log levels, setting up an SSH connection, etc.
Changing the Linux log level
The log level of the Linux system is set to 1 by default. When using the serial port to
view the boot logs, it only shows minimal information. We can increase the log levels
to get more detailed system logs for debugging.
The following command will change the log level to 7.
root@orangepi:~# sed -i "s/verbosity=1/verbosity=7/" /boot/orangepiEnv.txt
