• Formatting software SDFormatter
• Burning software Raspberry Pi Imager

Software needed for Windows

• Install rpiboot The sequence is used to turn the CM4 device into a computer disk. At this point the rpiboot installation is complete.

• Download and install the official SDFormatter or the SDFormatter from M5 link for disk cleaning and formatting.

Software needed for Linux

• On Linux, some programming knowledge is required. Compile the rpiboot tool and the libusb development library using the following commands:

sudo apt install git libusb-1.0-0-dev pkg-config
git clone --depth=1 https://github.com/raspberrypi/usbboot
cd usbboot
make
# sudo ./rpiboot

Starting the Burning Process
