• Setup the Build Environment
• VIM1S Download Android Source Code
• VIM1S Install Toolchains

$ cd PATH_YOUR_PROJECT
$ cd bootloader/uboot
$ ./mk kvim1s

Gernerate images in this step:

• build/u-boot.bin: for onboard eMMC storage booting
• build/u-boot.bin.sd.bin: for external TF card booting

$ ./mk kvim1s -v 5.4 -jN

$ cd PATH_YOUR_PROJECT
