Compile Android10.0 Download Android SDK Due to the larger SDK, you can choose the cloud disk to download Firefly-RK3399_Android10.0_git_20211222.7z from the download page : 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 $ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.004 $ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.005 fb41fcdc48b1cf90ecac4a5bb8fafc7a Firefly-RK3399_Android10.0_git_20211222.7z.001 82d665fb54fb41245d9317312e7b7578 Firefly-RK3399_Android10.0_git_20211222.7z.002 0dd40827976200a6fb61623c9e87fe7c Firefly-RK3399_Android10.0_git_20211222.7z.003 32324c3afe615394ee4cdf842c53ea8d Firefly-RK3399_Android10.0_git_20211222.7z.004 9b1656ae07b4fe9ddf7d9ef2dfa2f95a Firefly-RK3399_Android10.0_git_20211222.7z.005 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 AIO-3399J product compilation method Overall Compilation Public Compile HDMI ./FFTools/make.sh -j24 -d rk3399-firefly-aio -l rk3399_firefly_aio-userdebug ./FFTools/mkupdate/mkupdate.sh -l rk3399_firefly_aio-userdebug Display DM-M10R800 Compile LVDS+HDMI ./FFTools/make.sh -d rk3399-firefly-aio-lvds-HSX101H40C -j8 -l rk3399_firefly_aio_lvds-userdebug ./FFTools/mkupdate/mkupdate.sh -l rk3399_firefly_aio_lvds-userdebug Dual Camera SV-TAYSH-TQ Compile HDMI+SV-TAYSH-TQ note: The camera only supports aio-3399j Standard Edition and does not support HDMI_In version Modify kernel/arch/arm64/boot/dts/rockchip/rk3399-firefly-aio.dtsi xc7160b@1b{ + status = "disabled"; }; xc7160f@1b{ + status = "disabled"; }; XC6130b@23{ + status = "okay"; }; XC7022b@1b{ + status = "okay"; }; Compile ./FFTools/make.sh -j24 -d rk3399-firefly-aio -l rk3399_firefly_aio-userdebug ./FFTools/mkupdate/mkupdate.sh -l rk3399_firefly_aio-userdebug Compile step by step AIO-3399J Before compiling, execute the following command to configure environment variables: source ./FFTools/build.sh Compile kernel: cd ~/proj/rk3399_Android10.0/kernel/ make ARCH=arm64 firefly_defconfig android-10.config rk3399.config make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3399_firefly_aio/boot.img rk3399-firefly-aio.img -j8 Note：If you going to do kernel debug，you need pack the resource.img and kernel.img together into boot.img,then upgrade the boot,img into boot partition. Compile uboot： cd ~/proj/rk3399_Android10.0/u-boot/ ./make.sh rk3399 Compile Android： cd ~/proj/rk3399_Android10.0/ lunch rk3399_firefly_aio-userdebug make -j8 ./mkimage.sh Package into a unified firmware After compiling, execute the following command first, then use Firefly official script to package into a unified SD card firmware, execute the following command: ./FFTools/mkupdate/mkupdate.sh -l rk3399_firefly_aio-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 Packing the unified firmware "update.img" under Windows is also very simple. Copy the compiled files to the "rockdev/Image" directory of AndroidTool, and then run the "mkupdate.bat" batch file under the "rockdev" directory. Create "update.img" and store it in the "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 make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3399_firefly_aio/boot.img rk3399-firefly-aio.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 Flash Image Reference: 《Flash Image》 Other Android versions Main maintenance: "Compile Android7.1 Industry firmware" "Compile Android10.0" Support but not maintain: "Compile Android7.1 firmware" "Compile Android8.1"
