Flashing a Raspberry Pi CM5 with Ubuntu 20.04
I recently purchased a Raspberry Pi Compute Module 5 (CM5) and wanted to flash it with Ubuntu 20.04, but was faced with an error when trying to flash the image. This post will show you how to flash a Raspberry Pi CM5 with Ubuntu 20.04.
Prerequisites
- Raspberry Pi Compute Module 5 (not the Lite version as this uses an SD card)
- Raspberry Pi Compute Module 5 IO Board
Steps
Follow the steps in the official Raspberry Pi documentation (see below). The section titled ‘Set up the host device’ uses the rpiboot tool to flash the image to the CM5. However, I encountered an error when trying to flash the image using rpiboot.
When I attempted this, the rpiboot tool would hang at the following message:
1
Waiting for BCM2835/6/7/2711...
To fix this issue, I had to compile the rpiboot tool from source. Here are the steps I followed:
1
sudo apt remove rpiboot
and compiled following the instruction from: https://github.com/raspberrypi/usbboot

sudo apt install git libusb-1.0-0-dev pkg-config build-essential
git clone --recurse-submodules --shallow-submodules --depth=1 https://github.com/raspberrypi/usbboot
cd usbboot
make
sudo ./rpiboot
I got the error:

after specifying the directory I was able to flash the device
