Overview

Introduction

CM4-DUAL-ETH-WIFI6-BASE, the IO board of the Raspberry Pi Compute Module 4, is a carrier board that can be used with the Raspberry Pi Compute Module 4 and supports 7~12V DC power supply, and the board has three USB ports 2.0, WIFI6, dual Ethernet ports, suitable for soft routing and other scenarios that require multiple Ethernet ports.

Note

1. Do not unplug any device except USB and HDMI when the power is on.
2. Check the fan voltage before connecting. It supports 5V and 12V. The default connection is 12V. Before switching, please modify the resistance of FAN_VCC.
3. The Type C interface is only used as a USB SLAVE interface to burn images, and cannot be used as a power supply.
4. When CM4 is in normal use, it needs to provide at least a 12V 1.5A power supply. Otherwise, problems such as automatic shutdown and frequency reduction may occur.
5. See instructions for use about Opwenwrt.
6. This expansion board does not support the POE function.

Note

Do not plug or unplug any device while it is powered on.

Image Programming

RTC FAN

Fan

As shown in the figure, switch the FAN voltage according to the position of the resistor, and the default is 12V.
CM4-DUAL-ETH-WIFI6-BASE User guide01.png
The fan PWM pin is controlled by GPIO18.

RTC

RTC chip: PCF85063A
Default I2C: I2C1
I2C address: 0x51

sudo nano /boot/config.txt
#Add at the end
dtparam=i2c_arm=on
dtoverlay=i2c-rtc,pcf85063a
#Add # in front of dtparam=audio=on
#dtparam=audio=on
#Save and exit, restart
sudo reboot

Hwclock

Synchronize system clock -> hardware clock.

sudo hwclock -w

Synchronize hardware clock -> system clock.

sudo hwclock -s
  #Need to close the network, or close the network time, otherwise it will be changed back.

Set the hardware clock time:

sudo hwclock --set --date="9/8/2021 16:45:05"

View hardware clock.

sudo hwclock -r

Show version information.

sudo hwclock --verbose

CSI DSI

Configuration file

CSI and DSI are disabled by default. When using the camera and DSI, it will occupy three I2C devices: I2C-10, I2C-11, and I2C-0.

  • Open a terminal and run the following commands:
sudo apt-get install p7zip-full -y
wget https://files.waveshare.com/upload/7/75/CM4_dt_blob_Source.zip
7z x CM4_dt_blob.7z -O./CM4_dt_blob
sudo chmod 777 -R CM4_dt_blob
cd CM4_dt_blob/
# If using two cameras and DSI1 execute
sudo dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-disp1-double_cam.dts
# In the use of any DSI, HDMI1 no image output, even if you do not connect the DSI screen as long as the corresponding file compiled, that HDMI1 no output
# If you need to restore, delete the corresponding dt-blob.bin can be: sudo rm -rf /boot/dt-blob.bin 
#Execution is complete, power off and restart CM4


New Version (Bullseye)

Camera Config

  1. Execute the following commands to edit "/boot/config.txt" file.
    sudo nano /boot/config.txt
  2. Block or remove the automatic camera detection statement:
    CM4-NANO-B002.png
  3. Add the driver of the camera you are using, here I take IMX219 as an example and connect it to CAM0, and attach the adapter.
    CM4-NANO-B003.png
  4. Model CAM0 Set Sentence CAM1 Set Sentence
    OV9281 dtoverlay=ov9281,cam0 dtoverlay=ov9281,cam1
    IMX290/IMX327 dtoverlay=imx290,clock-frequency=37125000,cam0 dtoverlay=imx290,clock-frequency=37125000,cam1
    IMX378 dtoverlay=imx378,cam0 dtoverlay=imx378,cam1
    IMX219 dtoverlay=imx219,cam0 dtoverlay=imx219,cam1
    IMX477 dtoverlay=imx477,cam0 dtoverlay=imx477,cam1
    IMX708 dtoverlay=imx708,cam0 dtoverlay=imx708,cam1
    • If you are using the official Raspberry Pi camera and only one camera is connected, there is no need to set the config file.
    • CM4-NANO - only CAM0 is used, so you only need to add "dtoverlay=imx219,cam0".

    5. Ctrl+x to exit the editor.
    6. Reboot the Raspberry Pi.

    sudo reboot
    

Camera Test

  1. Enter the camera detection command, you can see that the camera is detected by now.
    libcamera-hello --list-cameras
    

    CM4-NANO-B005.png

  2. Display the camera screen on the desktop.
  3. libcamera-hello -t
    
  4. Taking photos.
    libcamera-jpeg -o test.jpg
    
  5. Record a video of 10s.
    libcamera-vid -t 10000 -o test.h264
    
  6. Other Commands
    Check whether the camera is detected:
    libcamera-hello --list-cameras

    Open the corresponding cameras:

    libcamera-hello  --camera 1
    libcamera-hello  --camera 0
    

    Take a photo:

    libcamera-jpeg -o test.jpg
    #Add --camera to specify a camera 
    

Old Version (Buster)

Camera Config

    1. Execute the following command to enter the Raspberry Pi configuration.
    sudo raspi-config

    2. Choose Interfacing Options and enter.

    3. Choose Camera:
    Camera.png
    4. Choose to enable the camera interface.
    Camera2.png
    5. The system prompts as follows:
    Prompt.png
    6. Back to the main interface, select Finish.
    Finish.png
    7. Reboot the system.

    Camera Test

    raspistill -o image.jpg
    
    • Test the recording function:
    raspivid -o video.h264 -t 10000
    
      • Where -t 10000 means recording for 10 seconds, users can adjust according to their own needs.
      • Please refer to CSI.

Openwrt

Openwrt has high customization and scalable performance. Openwrt is becoming more and more popular at present. Compared with commonly used wireless routers, OpenWrt's modifiable firmware allows us to customize router functions according to our own needs, such as single-arm routing, automatic Define routing policies, QoS, intranet penetration, etc.
Note: Openwrt system will not provide any technical support if there is any problem during use. Only the following tutorials and images are provided, and no additional technical support other than hardware is provided.

Image

If the board used does not have USB3.0, only USB 2.0, and the USB2.0 cannot work, try adding "otg_mode=1" at the end of config.txt.

Openwrt Configuration

The OpenWrt image configured above supports CM4 onboard Wifi and the driver of RTL8153. You can make CM4 into a smart router. Here is a tutorial on how to install Openwrt on the Raspberry Pi to realize the wireless router function, so that the devices in the LAN can access the Internet through the wireless router, and realize the intelligent management of the LAN. The overall network topology is shown below.
CM4-DUAL-ETH-BASE-openwrt-1.png
After booting up correctly, log in to the system:
The computer is connected to the ETH0 port, and then directly ssh remote login or web page login.
The configured system default IP is: 192.168.14.1
The default IP of the system without configuration is: 192.168.1.1
Account: root without password.

If you think the network port is not enough, you can buy USB 3.2 Gen1 TO Gigabit ETH RTL8153 expansion network port, if any ETH/USB HUB HAT RTL8152 can also expand the 100M Ethernet port and support it.

FAQ

 Answer:

a) Check whether dtparam -audio - on is blocked in /boot/config.txt.
b) Check if the /boot/dt-blob.bin file exists, if it is unusable, please delete it.
