Download link

Note: the source code and bundle are stored in the Google Driver

After downloading, verify the MD5 code:

$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.001
$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.002
$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.003

After confirming that it is correct, you can unzip:

cd ~/proj/
7z x ./Firefly-RK3399_Android10.0_git_20211222.7z.001 -ork3399_Android10.0
cd ./rk3399_Android10.0
git reset --hard

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/rk3399_Android10.0


2. Download remote bundle repository
git clone https://gitlab.com/TeeFirefly/rk3399-android10.0-bundle.git .bundle


3. If the download warehouse fails, the current bundle warehouse is about 1.4G, so there may be stuck or failed problems during synchronization. You can download and unzip it from the cloud disk link below to the SDK root directory.

7z x rk3399-android10.0-bundle.7z  -r -o. && mv rk3399-android10.0-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

Compile step by step AIO-3399C

Before compiling, execute the following command to configure environment variables:

source ./FFTools/build.sh

Compile kernel:

cd ~/proj/AIO-3399C/kernel/
make ARCH=arm64 firefly_defconfig android-10.config rk3399.config
AI version: make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3399_firefly_aioc_ai/boot.img rk3399-firefly-aioc-ai.img -j8

Compile uboot:

cd ~/proj/AIO-3399C/u-boot/
./make.sh rk3399

Compile Android:

cd ~/proj/AIO-3399C/
AI version: lunch rk3399_firefly_aioc_ai-userdebug
make -j8
./mkimage.sh

Packaged into unified firmware

After compilation, you can use Firefly official scripts to package into unified firmware, execute the following command：

AI version:./FFTools/mkupdate/mkupdate.sh -l rk3399_firefly_aioc_ai-userdebug

According to different -l XXX-userdebug parameters, the packaged unified firmware will be stored in different directories (rockdev/image-XXX/): 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 update.img and store it in rockdev \ Image directory.

Some Introduction about Compiling

Android 10.0 can't be written directly kernel.img and resource.img

Android 10.0 kernel.img and resource.img Included in boot.img After the kernel is updated and compiled, it needs to be executed in the Android root directory mkimage.sh Repackage boot.img .After packing, download boot.img in rockdev directory .You can compile the kernel separately by using the following instruction.

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 when compiling IMG = XXX parameter specification boot.img The command is as follows:

cd kernel
make ARCH=arm64 firefly_defconfig android-10.config
AI version: make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3399_firefly_aioc_ai/boot.img rk3399-firefly-aioc-ai.img -j24

After compiling, you can directly download the boot.img To the machine.

Partition image

boot.img include ramdis、kernel、dtb
dtbo.img Device Tree Overlays
kernel.img Currently, it cannot be burned separately, it needs to be packaged into boot.img to burn and write
MiniLoaderAll.bin include first loader
misc.img include recovery-wipe boot flag information ，enter recovery afte v
odm.img include android odm，included in super.img partition ,upgrade alone by the fastboot tool
parameter.txt include partition information
pcba_small_misc.img include pcba boot flag information，enter the simple pcba mode after upgrade
pcba_whole_misc.img include pcba boot flag information，enter the full pcba mode after upgrade
recovery.img include recovery-ramdis、kernel、dtb
resource.img include dtb，kernel and uboot phases log and the uboot charging logo,it should be packed into boot.img,then upgrade it
super.img include odm、vendor、system partition content
system.img include android system，included in super.img partition ,upgrade alone by the fastboot tool
trust.img include BL31、BL32
uboot.img include uboot.img
vbmeta.img include avb，for AVB verify
vendor.img 包含android vendor，included in super.img partition ,upgrade alone by the fastboot tool
update.img include all the img file above，use tools to upgrade the whole firmware package
