1. System image burning¶
Video introduction to this chapter:
“09-Comparison of several Linux system images of Lubancat”
https://www.bilibili.com/video/BV1Mg4y1V7bX/
Three steps are required to run the board: burn the system, start the system and log in the system.
The LubanCat-RK series boards with emmc have been burned with a system image by default when leaving the factory. If you do not need to burn a new image, you can skip this chapter.
The system image of LubanCat-RK series boards contains a variety of root file systems, we can choose the corresponding image to download according to our needs.
注意
System image is the core of LubanCat-RK board. It includes the linux kernel, basic programs, etc. It is necessary to run the LubanCat-RK board. So we need to install the image for the board before running the board.
