Precautions

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

PS: If you are using the system of the Bullseye branch, you need to change "apt-get" to "apt", the system of the Bullseye branch only supports Python3.

4G/5G

To work with 4G/5G, you need to connect a wireless module to the M.2 B KEY for featuring corresponding functions. M.2 B KEY only extends USB 3.0 interfaces, it doesn't support PCIe devices.
CMD-DUAL-ETH-4G5G-BASE-11.jpg
SIM card is required to work with the 4G/5G module.
If you want to disable the 4G/5G module, you can set the GPIO6 to High and enable it again by setting the GPIO6 to Low.
The module requires about 30s to enable/disable the 4G/5G modules.

RTC FAN

  • Note 1: Please connect the cooling fan before you power the whole device, otherwise, the control chip will be damaged!
  • Note 2: Please check the voltage before you connect the cooling fan, it is default 12V.

Use Raspberry Pi system (2021-05-07-raspios-buster-armhf-full)
DO NOT use DSI and CSI when using RTC.
If you need to use it at the same time, switch the I2C to the I2C1 device (right).
CM4-DUAL-ETH-4G-5G-BASE-12.png
All programs or drivers need to be modified after switching.
The demo uses I2C10 by default (left).

If you need to use it simply or add it to your program, refer to the C and Python demo reference [click here] The following is to add the driver to the kernel.

RTC

sudo nano /boot/config.txt
#Add at the end
dtparam=i2c_vc=on
dtoverlay=i2c-rtc,pcf85063a,i2c_csi_dsi
#Add # in front of dtparam=audio=on
#dtparam=audio=on
#Save and exit, restart
sudo reboot

Using Hwclock

  • Synchronize the system clock and the RTC.
sudo hwclock -w
  • Synchronize the hardware clock and the RTC.
sudo hwclock  -s

Note that it will be restored if the network is disabled.

  • Set hardware clock.
sudo hwclock --set --date="9/8/2021 16:45:05"
  • Check the hardware clock.
sudo hwclock -r
  • Check the version.
sudo hwclock --verbose

RTC Test

1. Download the test demo.

Open the terminal of the Raspberry Pi, and enter the following command:

sudo apt-get install p7zip-full
sudo wget https://files.waveshare.com/upload/4/42/PCF85063_code.7z
7z x PCF85063_code.7z -O./
cd PCF85063_code

2. Run the demo:

C

Execute the following commands to compile and execute the test demo:

cd c
sudo make clean
sudo make -j 8
sudo ./main

Python

Enter the python/example director:

cd python/example

And then run the Python demo, the demo can support python2/3.

# python2
sudo python main.py
# python3
sudo python3 main.py

The running result is as below:

RTC PCF85063 python test.png

FAN test

When powered on, the fan will spin for 1 second, then stop for 2 seconds, and then spin again. This is normal.
There is currently no official configuration method for fans, there is a third-party configuration method: https://github.com/neg2led/cm4io-fan
This method is released by a third party, not an official release, and we are not responsible for any problems!

mkdir -p ~/src
cd ~/src
git clone https://github.com/neg2led/cm4io-fan.git
cd cm4io-fan
sudo chmod 777 install.sh
sudo ./install.sh
#The following is a description of config.txt

Or directly refer to the following:
dtoverlay=cm4io-fan,minrpm=500,maxrpm=5000,midtemp=45000,midtemp_hyst=2000,maxtemp=50000,maxtemp_hyst=2000
The temperature is higher than 45 degrees Celsius and starts to accelerate, and the highest speed is higher than 50 degrees Celsius.

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".

    CM4-NANO-B004.png
    5. Ctrl+x to exit the editor.
    6. Reboot the Raspberry Pi.

    sudo reboot

      • 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, etc., intranet penetration, etc.

Openwrt Configuration

Note: The 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 other technical support other than hardware is provided. The OpenWrt image configured above supports CM4 onboard wifi and the driver of RTL8153. CM4 can be turned into a smart router,
The following will tell you how to install Openwrt on the Raspberry Pi to realize the function of a wireless router so that the devices in the local area network can access the Internet through the wireless router, and realize the intelligent management of the local area network. 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 interface, 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
