2. Compile Source

2.1 Android 14

❶ Extract Source Code

1tar xvf Rockchip_Android14.0_SDK_RELEASE_20260115.tar.bz2
2cd Rockchip_Android14.0_SDK_RELEASE_20260115

❷ Configuration

1source build/envsetup.sh
2lunch em3588_u-userdebug

❸ One key compiling

1./build.sh -AUCKu
Serial terminal output
./build.sh -UKAup
（ WHERE: -U = build uboot
-C = build kernel with Clang
-K = build kernel
-A = build android
-p = will build packaging in IMAGE
-o = build OTA package
-u = build update.img
-v = build android with 'user' or 'userdebug'
-d = huild kernel dts name
-V = build version
-J = build jobs
------------you can use according to the requirement, no need to record
uboot/kernel compiling commands------------------
）
============================================================
Please remember to set the environment variable before using the one key
compiling command, and select the platform to be compiled, for example:
source build/envsetup.sh
lunch rk3588_t-userdebug
============================================================

After the command is completed, the image files will be generated in the rockdev/ Image-em3588_u directory.

Note

The kernel compiled here is only for generating the resource.img. The kernel source code will be compiled into KO files and packaged into vendor_boot.img. The kernel part uses the boot.img released by Google, and the specific path is in mkcombinedroot/prebuilts/boot-6.1.img Compiling vendor_boot.img solely is also supported during debugging.

Execute the following command:

1make installclean;make vendorbootimage -j12

Flash directly after compiling out/target/product/em3588_u/vendor_boot.img

2.2 Android 16

The Rockchip Android 16.0 SSI SDK provides only the AOSP codebase. After compilation, it generates only system-related images (system.img, system_ext.img, product.img), which are identical to Google’s GSI images. Other code modules must be compiled using the Android 14 SDK. Therefore, the Rockchip Android 16.0 SSI SDK must be used in conjunction with the Android 14 SDK. The architecture diagram of the complete SDK (comprising both the Rockchip Android 16 SSI SDK and the Android 14 SDK) is shown below:

Lunch menu .. Here are the common combinations:
     1. PX30_u-user
     2. PX30_u-userdebug
     3. aosp_arm-eng
     4. aosp_arm64-eng

Please enter the lunch option for Android_VENDOR_SDK (for example: rk3588_u-user):em3588_u-userdebug

Do you need to specify the build number? (Press Enter to automatically generate, or directly enter the required build number):8

Current PRODUCT_KERNEL_DTS=em3588-u, If you need to modify the DTS, please enter. Press Enter to use the default value:

  • Enter parameters in format or press Enter to input interactively: Press Enter, then input the path of the Android 14 SDK.

  • Please enter the lunch option for Android_VENDOR_SDK (for example: rk3588_u-user): Select em3588_u-userdebug

  • Do you need to specify the build number?: Input the build number here, such as 8.

  • Current PRODUCT_KERNEL_DTS=em3588-u, If you need to modify the DTS, please enter. Press Enter to use the default value: Press Enter

❹ Compile

1rkbuild_build all
Partial Compilation
rkbuild_build { uboot | kernel | ssi | vendor | all }
- uboot: Build the uboot in Android_VENDOR_SDK
- kernel: Build the kernel modules in Android_VENDOR_SDK
- ssi: Build the system SDK
- vendor: Build the GRF SDK
- all: Build the uboot & kernel & ssi & vendor, then pack the images to update.img

For partial compilation, need to perform merge operation after compilation:

1rkbuild_merge
2rkbuild_mkupdate

The path of the compiled firmware is /Rockchip_Android16.0_SDK_RELEASE_20260114/rockdev/Image-em3588_u/
