3. Compile Android12.0 firmware¶
3.1. Download Android12.0 SDK¶
SDK source code and bundle compression package are stored in the Google Drive.
3.1.1. Download Android SDK¶
The SDK can be obtained by email. Send the order number to sales@t-firefly.com and indicate the required SDK name firefly_rk3588_android12_git_20240704
After downloading, verify the MD5 code:
$ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.001 $ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.002 $ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.003 $ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.004 $ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.005 $ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.006 $ md5sum /path/to/firefly_rk3588_android12_git_20240704.7z.007 1ce2a5ab4e3a9f0a4d6d8cd47ca4981d firefly_rk3588_android12_git_20240704.7z.001 553fb5ee2cc5623d97bfb19ba299605b firefly_rk3588_android12_git_20240704.7z.002 cb9cce227a79356fa57c0781a426fd89 firefly_rk3588_android12_git_20240704.7z.003 1461a09bacbef0cb3c9a9008e8483e93 firefly_rk3588_android12_git_20240704.7z.004 d154b39087bbf410a7973da97a6a9ecb firefly_rk3588_android12_git_20240704.7z.005 7cfc42443caa57cb4cf474bf3e78b5ce firefly_rk3588_android12_git_20240704.7z.006 9ad4374d89212a882dc00541769732f8 firefly_rk3588_android12_git_20240704.7z.007
After confirming that it is correct, we can unzip:
cd ~/proj/ 7z x ./firefly_rk3588_android12_git_20240704.7z.001 -oRK3588_Android12.0 cd ./RK3588_Android12.0 git reset --hard
Attention: To avoid unnecessary errors, please do not unzip the SDK in shared folders, mounted folders or non-english directories.
3.1.1.1. Second, Update SDK¶
Note: Be sure to update the remote warehouse after decompression. The following is how to update from gitlab:
1. Enter the SDK root directory
cd ~/proj/RK3588_Android12.0
2. Download remote bundle repository
git clone https://gitlab.com/T-Firefly/rk3588-android12.0-bundle.git .bundle
3. If the download warehouse fails, it may be stuck or failed problems during synchronization.
we can download and unzip it from the cloud disk link below to the SDK root directory.
7z x rk3588-android12.0-bundle.7z -r -o. && mv rk3588-android12.0-bundle .bundle
4. Update the SDK, and subsequent updates do not need to pull the remote warehouse again, just execute the following command
.bundle/update
5. Follow the prompts to update the content to FETCH_HEAD, synchronize FETCH_HEAD to the firefly branch
git rebase FETCH_HEAD

3.2.2. Step by step to compile¶
Compile the kernel:
cd ~/path/to/sdk/kernel-5.10
export PATH=../prebuilts/clang/host/linux-x86/clang-r416183b/bin:$PATH
alias msk='make CROSS_COMPILE=aarch64-linux-gnu- LLVM=1 LLVM_IAS=1'
msk ARCH=arm64 firefly_defconfig android-11.config pcie_wifi.config
msk ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3588_firefly_aio_3588q/boot.img rk3588-firefly-aio-3588q.img -j8
Compile uboot:
cd ~/path/to/sdk/u-boot/
./make.sh rk3588
Compile Android：
cd ~/path/to/sdk/
source build/envsetup.sh
lunch rk3588_firefly_aio_3588q-userdebug
make installclean
make -j8
./mkimage.sh
3.2.3. Packaged into unified firmware update.img¶
After compilation, you can use Firefly official scripts to package into unified firmware, execute the following command：
./FFTools/mkupdate/mkupdate.sh -l rk3588_firefly_aio_3588q-userdebug
After packaging, it will be in rockdev/Image-rk3588_firefly_aio_3588q/ Generate unified firmware under the directory: (product name )XXX_XXX_date XXX.img
It is also very simple to package the unified firmware update.img under Windows. Copy the generated files to the rockdev \ Image directory of AndroidTool, and then run the mkupdate.bat batch file under the rockdev directory to create up date.img and store it in rockdev \ Image directory.
3.3. Some Introduction about Compiling¶
3.3.1. Android12.0 can’t be upgraded directly kernel.img and resource.img¶
kernel.img and resource.img for Android12.0 are included in boot.img, After compiling the kernel, you need to run the ./mkimage.sh command in the android root directory to repackage boot.img, and then upgrade boot.img of the rockdev/Image-rk3588_firefly_aio_3588q/ directory.
3.3.2. Compiling kernel generation separately boot.img¶
Principle of compilation: in the kernel directory, the generated kernel.img And resource.img Replace with old boot.img, so you need to use BOOT_IMG=XXX parameter specification boot.img when compiling. The command is as follows:
cd ~/proj/RK3588_Android12.0/kernel-5.10
export PATH=../prebuilts/clang/host/linux-x86/clang-r416183b/bin:$PATH
alias msk='make CROSS_COMPILE=aarch64-linux-gnu- LLVM=1 LLVM_IAS=1'
msk ARCH=arm64 firefly_defconfig android-11.config pcie_wifi.config
msk ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3588_firefly_aio_3588q/boot.img rk3588-firefly-aio-3588q.img -j8
After compiling, boot.img in the kernel directory can be directly upgrade.
3.4. Partition image¶
When compiling, executing ./mkimage.sh will repackage boot.img and super.img, and copy other related image files to the directory rockdev/Image-rk3588_firefly_aio_3588q/. The following lists the image files used by general firmware:
| Image | Instruction |
|---|---|
| boot.img | including ramdis、kernel、dtb |
| dtbo.img | Device Tree Overlays |
| MiniLoaderAll.bin | including first level loader |
| misc.img | including recovery-wipe boot symbol information, after flashing it will enter recovery |
| parameter.txt | including partition information |
| recovery.img | including recovery-ramdis、kernel、dtb |
| super.img | including the contents of odm、vendor、system partitions |
| uboot.img | including uboot image |
| vbmeta.img | including avb verification information, used for AVB verification |
| update.img | including the above img files to be flashed, can be used for the tool to directly flash the whole image package |
For details about how to upgrade a partition image file, see Upgrade the firmware via USB cable.
