How to bulid a image with BSP
Download and compile BSP code
Here I use BPI-M4 as an example:
1. Execute command: "git clone https://github.com/BPI-SINOVOIP/BPI-M4-bsp.git" to download bsp code.
2. Execute command: "./build.sh" then choose "1" to build the bsp
3. After built bsp code, the boot and kernel files will be generated in "SD/bpi-m4".
