I am unable to get the CM5 to boot from microSD. I am using a SanDisk High Endurance 128GB microSD card and wrote Raspberry Pi OS (64-bit) using Raspberry Pi Imager 2.0.11.1. The write and verification both complete successfully.

With the microSD installed and 12V/3A power applied:
  • Red power LED remains on.
  • RUN/status LEDs illuminate briefly at startup and then turn off.
  • Fan starts.
  • No HDMI output.
  • No Ethernet link/activity lights.
  • Device does not appear on the network.
I have rewritten and verified the microSD image multiple times with the same result. The CM5 is the Lite version without eMMC, so my understanding is that booting Raspberry Pi OS from the Pi5R8 microSD slot is the correct procedure.

I also installed rpiboot on Windows and connected the Pi5R8 USB-C port to the PC. rpiboot remains at “Waiting for BCM2835/6/7/2711/2712…” and does not detect the CM5.
The five DIP switches are still in their factory positions; I have not changed them.

Is there a jumper, DIP-switch setting, or other configuration required for the Pi5R8 with a CM5 Lite to boot from microSD? If not, what would you recommend checking next?]]>

2. enable i2c for home assistant.

Add files to enable I2C

In the root of the hassos-boot partition, add a new folder called CONFIG.
In the CONFIG folder, add another new folder called modules.
Inside the modules folder add a text file called rpi-i2c.conf with the following content:
i2c-dev

In the root of the hassos-boot partition, edit the file called config.txt at last add two lines to it:
dtparam=i2c_arm=on
dtoverlay=i2c1-pi5,pins_2_3

Note: if you using Windows OS computer, you can use "DiskGenius.exe" free software to modify the files. Because Linux format file not visable on windows OS.

2. In the Pi OS configuration graphical interface, enable I2C and serial port, and disable the serial monitor function.

3. By default, the /dev/ttyAMA0 serial port is enabled, but you need to edit the file to enable the /dev/ttyAMA2 serial port.

Run the command:
sudo nano /boot/firmware/config.txt
Add the following lines:

dtoverlay=uart2
dtoverlay=uart3
Save the file and exit.

The serial port mappings are as follows:

Code:
Serial Port    Device File    Physical Pins (Board)    BCM Pins (GPIO)
UART2    /dev/ttyAMA1    Pin 27 (TXD) / 28 (RXD)    GPIO 0 / 1
UART3    /dev/ttyAMA2    Pin 13 (TXD) / 14 (RXD)    GPIO 4 / 5
UART4    /dev/ttyAMA3    Pin 7 (TXD) / 21 (RXD)    GPIO 8 / 9
UART5    /dev/ttyAMA4    Pin 29 (TXD) / 30 (RXD)    GPIO 12 / 13
