  3. Open festal file sudo nano /etc/festal

  4. Add the following to the festal file UUID=5C24-1453 /mnt/mydisk stipe defaults,auto,users,rw,nofail 0 0 Replace stipe with the type of your file system, which you can find in step 2 of “Mounting storage devices” above, for example, nets.

  5. If the file system type is FAT or NTFS, add unmask = 000 immediately after onfall, which will allow all users to have full read/write access to every file on the storage device.

You can use man festal to find more information about festal commands.

4.2 Ethernet Configuration
4.2.1 Gigabit Ethernet

There is an adaptive 10/100/1000Mbsp Ethernet interface on ED-CM4IO Computer, and it is recommended to use Cat6 (Category 6) network cable to cooperate with it. By  default, the system uses DHCP to automatically obtain IP. The interface supports PoE and has ESD protection. PoE signal introduced from RJ45 connector is connected  to the pin of J9 socket.
NOTE:Because PoE module only provides +5V power supply and cannot generate +12V power supply, PCIe expansion cards and fans will not work when using PoE power supply.

4.2.2 Using The Network Manager To Configure
If you use the desktop image, it is recommended to install the Network Manager plug-in network manager-gnome. After installation, you can directly configure the network through the desktop icon. sudo apt update sudo apt install network-manager-gnome sudo reboot
NOTE: If use our factory image, the network-manager tool and the network- manager-gnome plug-in are installed by default.

NOTE: If use our factory image, the Network Manager service is automatically started and the dhcpcd service is disabled by default.
After the installation is completed, you will see the Network Manager icon in the status bar of the system desktop.

Right-click the Network Manager icon and select Edit Connections。

Select the connection name to modify, and then click the gear below.

Switch to the configuration page of IPv4 Settings. If you want to set static IP, the Method selects Manual, and Addresses the IP you want to configure. If you want to set it as  dynamic IP acquisition, just configure the Method as Automatic(DHCP) and restart the device.

If you use the Raspberry Pi OS Lite, you can configure it through the command line.
If you want to use the command to set the static IP for the device, you can refer to the following methods.
set the static IP
sudo nuclei connection modify ipv4.addresses 192.168.1.101/24 ipv4.method manual set the gateway
sudo nuclei connection modify ipv4.gateway 192.168.1.1
Set dynamic IP acquisition
sudo nuclei connection modify ipv4.method auto

4.2.3 Configuration With dhcpcd Tool

The official system of Raspberry Pi uses dhcpcd as the network management tool by default.
If you use the factory image provided by us and want to switch from Network Manager to dhcpcd network management tool, you need to stop and disable Network Manager service and enable dhcpcd service first.
sudo systemctl stop Network Manager
sudo systemctl disable Network Manager
sudo systemctl enable dhcpcd
sudo reboot

The dhcpcd tool can be used after the system is restarted.
Static IP can be set by modifying.etc.dhcpcd.com. For example, eth0 can be set, and users can set wlan0 and other network interfaces according to their different needs.

4.5 RTC
The ED-CM4IO Computer is integrated with RTC and uses CR2032 button cell. RTC chip is mounted on i2c-10 bus.
Enabling I2C bus of RTC needs to be configured in config.txt
Dataram=i2c_vc=on

NOTE:The address of RTC chip is 0x51.
We provide an automatic synchronization BSP package for RTC, so you can use RTC without feeling. If you install the official system of Raspberry Pie, you can install the  “ed-retch” package. Please refer to the detailed installation process Install BSP Online Based On The Original Raspberry Pi OS.
The principle of RTC automatic synchronization service is as follows:

  • When the system is turned on, the service automatically reads the saved time from RTC and synchronizes it to the system time.
  • If there is an Internet connection, the system will automatically synchronize the time from the NTP server and update the local system time with Internet time.
  • When the system is shut down, the service automatically writes the system time into RTC and updates the RTC time.
  • Because of the installation of button cell, although the CM4 IO Computer is powered off, the RTC is still working and timing.

In this way, we can ensure that our time is accurate and reliable.
If you don’t want to use this service, you can turn it off manually:
sudo systemctl disable retch
sudo reboot
Re-enable this service:
sudo systemctl enable retch
sudo reboot
Read RTC Time manually:
sudo hemlock -r
2022-11-09 07:07:30.478488+00:00
Manually synchronize RTC time to the system:
sudo hemlock -s
Write the system time into RTC:
sudo hemlock -w

4.6 Power ON/OFF Button

ED-CM4IO Computer has the function of one-button power on/off. Forcibly turning off the power supply during the operation may damage the file system and cause the  system to crash. One-button power on/off is realized by combining Raspberry Pi’s Bootloader and 40PIN’s GPIO through software, which is different from the traditional power on/off by hardware.
One-button power on/off uses GPIO3 on the 40-pin socket. If you want to realize the one-button power on/off function, this pin should be configured as ordinary GPIO  function, and can no longer be defined as SCL1 of I2C. Please remap I2C function to other pins.
When the +12V input power supply is connected, pressing the key continuously will trigger the CM4 module to turn off and on alternately.
NOTE:To realize the one-button on-off function, it is necessary to install the factory image or the BSP package provided by us.
4.7 LED Indication
ED-CM4IO Computer has two indicator lights, the red LED is connected with the LED_PI_nPWR pin of CM4, which is the power indicator light, and the green LED is  connected with the LED_PI_nACTIVITY pin of CM4, which is the running status indicator light.
4.8 Fan Control
CM4 IO Computer supports PWM drive and speed control fan. The fan power supply is +12V, which comes from the +12V input power supply.
The chip of fan controller is mounted on i2c-10 bus. To enable I2C bus of fan controller, it needs to be configured in config.txt
Dataram=i2c_vc=on
NOTE:The address of the fan controller chip on I2C bus is 0x2f.
4.8.1 Install The Fan Control Package
First, install the fan BSP package ed-cm4io-fan through apt-get. Please refer to for details Install BSP Online Based On The Original Raspberry Pi OS.
4.8.2 Set Fan Speed
After installing ed-cm4io-fan, you can use the set_fan_range command and the nonmanual command to automatically configure and manually set the fan speed.

  1. Automatic control of fan speed
    The set_fan_range command sets the temperature range. Below the lower temperature limit, the fan stops working, and above the upper temperature limit, the fan runs at full speed.
    set_fan_range -l [low] -m [mid] -h [high] Set the fan monitoring temperature range, low temperature is 45 degrees, medium temperature is 55 degrees, and high temperature is 65 degrees.
    set_fan_range -l 45 -m 55 -h 65
    When the temperature is lower than 45 ℃, the fan stops output.
    When the temperature is higher than 45 ℃ and lower than 55 ℃, the fan will output at 50% speed.
    When the temperature is higher than 55 ℃ and lower than 65 ℃, the fan will output at 75% speed.
    When the temperature is higher than 65 ℃, the fan will output at 100% speed.

  2. Manually set the fan speed.

    Stop the fan control service first

    sudo systemctl stop fan_control.service

    Manually set the fan speed, and then enter the parameters as prompted.
