Compute Module 4 IO Board
Raspberry Pi Compute Module 4 IO Board, A Development Platform And Reference Base-Board Design For CM4
- If the CM4 you get is the Lite version, you just need to write an image to the SD card as you do for the Raspberry Pi board.
- If the CM4 you get has eMMC, you need to insert it on the IO board and then write the image use the IO Board.
CSI and DSI are disabled by default. I2C-10、I2C-11、I2C-0 should be used for Camera and DSI displays.
Open a terminal and run the following commands:
sudo apt-get install p7zip-full wget https://www.waveshare.com/w/upload/4/41/CM4_dt_blob.7z 7z x CM4_dt_blob.7z -O./CM4_dt_blob sudo chmod 777 -R CM4_dt_blob cd CM4_dt_blob/ #If you want to use both cameras and DSI0 sudo dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-disp0-double_cam.dts #If you want to ue both cameras and DSI1 sudo dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-disp1-double_cam.dts #HDMI1 is disabled if you use DSI interfaces for displayin. HDMI1 cannot work even thought you just built the file without connecting DSI display, please note it. #If you want to enable the HDMI1, please remove the dt-blob.bin file with the command: '''sudo rm -rf /boot/dt-blob.bin''' #Turn off IO Board and re-power the CM4
Connect Cameras and DSI display
1: Please first disconnect power off the IP Board when connecting.
2: Use CM-DSI-ADAPTER to connect Compute Module 4 PoE Board and DSI displays
3: UseCSI adapter cable to connect Compute Module 4 PoE Board and CSI cameras.
3: Connect the power adapter
4: Wait for booting.
5: If the DSI display cannot work, please check if you have added /boot/dt-blob.bin and reboot.
6: Please enable camera by raspi-config, choose Interfacing Options->Camera->Yes->Finish-Yesand reboot
Test RPi Camera:
sudo raspivid -t 0 -cs 0
sudo raspivid -t 0 -cs 1
