:1. You can use Raspberry Pi Imager to Flash or the following alternatives tools::* [https://etcher.balena.io/ balenaEtcher]: The application runs on Windows, MacOS, and Ubuntu operating systems.:* [https://i-win32diskimager.com/ Win32 Disk Imager]: This imaging software is designed for Windows machines.1:2. Flash OS image to a microSD memory card by following [https://docs.pikvm.org/flashing_os the simple instructions] or [https://www.raspberrypi.com/documentation/computers/getting-started.html#installing-the-operating-system Official installation tutorial]

2:3. Refer to [[#How to flash OS onto the eMMC of CM4? (CM4 with eMMC)?]] if you use the CM4 shield with eMMC.

3:4. Then power the device, then open explore to login the pikvm web ui.

:1. Short nBOOT Pin, refer to the picture below.

:2. Connect CM4 USB port with a Type-A to Type-B cable to your computer as follow:

:[[File:X680-IMG-5546-3.jpg|500px]]

:3. Power the device via PWR DC Jack with 5V Power adaper

:4. Then rerfer to [https://www.jeffgeerling.com/blog/2020/how-flash-raspberry-pi-os-compute-module-4-emmc-usbboot this tutorial] to flash raspberry pi OS

:5. Remove the jumper of nBOOT after flashing is complete, then restart your device;
