3. Build

3.1 Full Build

./build.sh all

After the build completes, the full firmware is generated at output/update/update.img.

3.2 Partial Build

After running a full build once, if you later modify the kernel or uboot, you can run partial builds to speed things up.

Build u-boot only, produces uboot/uboot.img

./build.sh uboot

Build the kernel only, produces kernel/extboot.img

./build.sh extboot

Pack all components into update.img

./build.sh updateimg
