- Page 3 ON/OFF switch of CM4 IO Case is driven by Bootloader & 40pin GPIO driver of CM4, so it controls the system on/off by software. It is not a traditional switch which cut off or turn on the power supply of the board. Forcing the power shutdown during CM4 operation may damage the file system and cause the system crash.
- Page 4 Software Installation Guide of CM4 IO Case 2. Software Installation 2.1. Modify Bootloader ⚫ Firstly test whether the bootloader on your CM4 supports software boot. Power on CM4 and type the following command: pi@raspberrypi:~ $ vcgencmd bootloader_config As above shows, if there appears “WAKE_ON_GPIO=1” and “POWER_OFF_ON_HALT=0”, then you can skip the step 2.1 and turn to step 2.2...

- Page 6 Software Installation Guide of CM4 IO Case ⚫ Run “rpiboot” on PI3B+, prepare for the bootloader burning and wait the CM4 IO board power on. pi@raspberrypi:~/work/test1/usbboot $ sudo ./rpiboot -v -d recovery/ ⚫ Power CM4 IO on, then the following print information appears at the terminal of PI3B+.
- Page 7 We just need to check the function of GPIO3 to make sure GPIO3 is configured as a normal GPIO function. If the GPIO3 in your CM4 IO is configured as with I2C function, you will need to overwrite the CM4 device tree file under the boot folder with the “bcm2711-rpi-cm4.dtb”...
- Page 8 ⚫ After the system shuts down, power off CM4 IO. Connect the two Dupont cables of the switch inside the case with CM4 IO, the red cable is connected to Pin3 and the black cable is connected to Pin39, as the following pictures show.
