Make the file system for the ARM development board under Linux

1.Busybox source code please download on the Internet, compile method please refer to Baidu.

2. Please also set the Settings of cross-compilation tool chain first.

If there are no problems with 1 and 2 above, you can use the following script to make a file system for the ARM development board.

You can customize it by yourself and add your own Test demo.

#!/bin/bash

# File system and Busybox The path of the ====> Customizable 
FILESYSTEM=/Softwave/filesystem         # Define the location of your own file system
