This guide is designed for ROCK Pi 4 enthusiast. The purpose is to learn about the ROCK Pi 4 board as well as how to prepare and set up for basic use. The ROCK Pi 4 has two models, one called ROCK Pi 4 Model A and the other called ROCK Pi 4 Model B. When you get a board, you need to know what Pi model it is and which hardware version it is. The information is printed in the top side of the board. We will introduce the board information as much as possible.

ROCK Pi 4 can be started with eMMC or μSD Card. Now, you are presented with two options when installing your new operating system onto your ROCK Pi 4.
Insert eMMC Module into eMMC to μSD card converter board. Insert the converter board into μSD Card Reader, which connects to host computer. The picture below shows.
(add eMMC, eMMC to μSD Module and μSD Card Reader picture)
If you do not have an eMMC to μSD card converter board, you can also first install a linux system to a μSD Card and then use the running μSD System to install the desired system to the eMMC card with the eMMC card already inserted into the Rock PI 4. See Rockpi4/install/eMMC.
Insert the μSD Card into μSD Card Reader, which connects to host computer. The picture below shows.

If you get an error message: "No polkit authentication agent found" you can try and start it with sudo, but do know that this is running the tool as root.
Wish you good luck!
