Software support
In order to get the top panel OLED display and fan working properly, we provide the rockpi-penta package, which can be installed with the following command.
sudo apt update
sudo apt install wget
wget https://github.com/radxa/rockpi-penta/releases/download/v0.2.2/rockpi-penta-0.2.2.deb
sudo apt install -y ./rockpi-penta-0.2.2.deb
Software configuration
After installing the package, if you need to modify the configuration, you can edit the configuration file /etc/rockpi-penta.conf, the following is the default value of the configuration file.

# When the temperature is above lv0 (35'C), the fan at 25% power,
# and lv1 at 50% power, lv2 at 75% power, and lv3 at 100% power.
# When the temperature is below lv0, the fan is turned off.
# You can change these values if necessary.
lv0 = 35
lv1 = 40
lv2 = 45
lv3 = 50
[key]
# You can customize the function of the key, currently available functions are

After modifying the configuration, run the sudo systemctl restart rockpi-penta.service command to restart the service for the configuration to take effect.
