Building Android Source Code

Preparations

• [x] Establishing a Build Environment
• [x] Downloading the Android Source
• [x] Install Toolchains for the Amlogic Platform

Building

Note: Before you start to build, make sure you have done all the Preparations listed above.

Build U-Boot:

$ cd PATH_YOUR_PROJECT
$ cd bootloader/uboot
$ ./mk kvim3

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

Build Android:

$ cd PATH_YOUR_PROJECT
$ source build/envsetup.sh
$ lunch kvim3-userdebug
$ make -jN otapackage

Note:

• Replace ‘N’ as the number you want when you run ‘make -jN’

Gernerate images in this step:

• out/target/product/kvim3/update.img

Build Linux kernel:

When you build the Android Kernel (above), the Linux Kernel will also be built simultaneously.

In some cases, you might want to build the Linux Kernel separately. You can run this script below to do that:

$ make bootimage
