Step One: 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".

Step Two: Install an image on SD card

1. You could install an image by following here: Install Linux & Android images on Banana pi SBC

2. Here I install an image under a ubuntu os, “bpi-copy 2019-07-23-ubuntu-18.04-mate-desktop-preview-bpi-w2-m4-sd-emmc.img.zip /dev/sde”

Step Three: Make an image

1. Our bsp could not build an image directly, so we need to make an image from sd card which has been installed an image.

2. Plug sd card which we just installed an image into a ubuntu PC, then the PC will recognize "BPI-BOOT" and "BPI-ROOT".

3. Now we do some preparations before make an image:

  • "cd /media", then "ln -s <your account> pi"
  • "mkdir <directory>", then “cp <BPI-M4-Project>/SD/bpi-m4/*.tgz <BPI-M4-Project>/SD/bpi-m4/100MB/* image”

4. As you can see, I linked an account called "pi" under "/media", created an folder and copied all the bsp files into it.

5. Now we could use command "bpi-migrate -c bpi-w2-m4.conf -c ubuntu-18.04-mate-from-sd.conf"

6. This command will copy the os from the sd card, and replace new kernel and uboot you just built in the new image.
