Environment Setup

First, you need a computer or virtual machine with Ubuntu installed. Version 20.04 is recommended. The username should not contain Chinese characters.

3. Compilation

3.1 Full Compilation

./build.sh all

After compilation, the complete firmware output/update/update.img will be generated.

3.2 Partial Compilation

After a full compilation, if you subsequently modify the kernel or uboot, you can partially compile to speed up.

Compile u-boot separately, generate uboot/uboot.img

./build.sh uboot

Compile kernel separately, generate kernel/extboot.img

./build.sh extboot

Package each component into update.img

./build.sh updateimg
