3. Compile Android14.0 firmware¶
3.1. Download Android14.0 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_rk3576_android14.0_git_20241126
After downloading, verify the MD5 code:
$ md5sum /path/to/firefly_rk3576_android14.0_git_20241126.7z.001 $ md5sum /path/to/firefly_rk3576_android14.0_git_20241126.7z.002 $ md5sum /path/to/firefly_rk3576_android14.0_git_20241126.7z.003 $ md5sum /path/to/firefly_rk3576_android14.0_git_20241126.7z.004 $ md5sum /path/to/firefly_rk3576_android14.0_git_20241126.7z.005 $ md5sum /path/to/firefly_rk3576_android14.0_git_20241126.7z.006 e368c4274125e754eeea35a97306e47b firefly_rk3576_android14.0_git_20241126.7z.001 d4436c73b800523dbb1df2ae0d524b26 firefly_rk3576_android14.0_git_20241126.7z.002 9f6a7ed4f01a8952c135cc5bf6fd4ecd firefly_rk3576_android14.0_git_20241126.7z.003 3d2babe7c2c9f737d23e8843c2df3117 firefly_rk3576_android14.0_git_20241126.7z.004 1d9ae98cc3e0959de19bc1dd628ed112 firefly_rk3576_android14.0_git_20241126.7z.005 09e35581108741bf4a564829edcd1a5f firefly_rk3576_android14.0_git_20241126.7z.006
After confirming that it is correct, we can unzip:
cd ~/proj/ 7z x ./firefly_rk3576_android14.0_git_20241126.7z.001 -oRK3576_Android14.0 cd ./RK3576_Android14.0 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¶
How to update code after downloading SDK:
1. Enter the SDK root directory
cd ~/proj/RK3576_Android14.0
2. we can download and unzip it from the cloud disk link below to the SDK root directory.
7z x rk3576-android14.0-bundle.7z -r -o. && mv rk3576-android14.0-bundle .bundle
3. Update the SDK
.bundle/update
4. Follow the prompts to update the content to FETCH_HEAD, synchronize FETCH_HEAD to the firefly branch
git rebase FETCH_HEAD
Google Driver Android14.0 Bundle。
3.2. iCore-3576Q product compilation method¶
3.2.1. The overall compilation¶
3.2.1.1. HDMI Firmware Compilation¶
./FFTools/make.sh -j8 -l rk3576_firefly_aio_3576q-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3576_firefly_aio_3576q-userdebug
3.2.1.2. 10.1‘ MIPI V3S Firmware Compilation：¶
./FFTools/make.sh -j8 -l rk3576_firefly_aio_3576q_mipi-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3576_firefly_aio_3576q_mipi-userdebug
3.2.2. Step by step to compile¶
Compile the kernel:
cd ~/proj/RK3576_Android14.0/kernel-6.10
export PATH=../prebuilts/clang/host/linux-x86/clang-r487747c/bin:$PATH
alias msk='make CROSS_COMPILE=aarch64-linux-gnu- LLVM=1 LLVM_IAS=1'
msk ARCH=arm64 firefly_defconfig android-14.config rk3576.config
msk ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3576_firefly_aio_3576q/boot.img rk3576-firefly-aio-3576q.img -j8
Compile uboot:
cd ~/proj/RK3588_Android14.0/u-boot/
make rk3576_defconfig
./make.sh --spl-new
Compile Android：
cd ~/proj/RK3588_Android14.0/
source build/envsetup.sh
lunch rk3576_firefly_aio_3576q-userdebug
make installclean
make -j8
./mkimage.sh
3.2.3. Packaged into unified firmware update.img¶
After compilation, you can use Firefly official scripts to package into unified firmware, execute the following command：
./FFTools/mkupdate/mkupdate.sh -l rk3576_firefly_aio_3576q-userdebug
After packaging, it will be in rockdev// Generate unified firmware under the directory: (product name )XXX_XXX_date XXX.img
It is also very simple to package the unified firmware update.img under Windows. Copy the generated files to the rockdev \ Image directory of AndroidTool, and then run the mkupdate.bat batch file under the rockdev directory to create up date.img and store it in rockdev \ Image directory.
3.3. Some Introduction about Compiling¶
3.3.1. Android14.0 can’t be upgraded directly kernel.img and resource.img¶
kernel.img and resource.img for Android14.0 are included in boot.img, After compiling the kernel, you need to run the ./mkimage.sh command in the android root directory to repackage boot.img, and then upgrade boot.img of the rockdev// directory.
3.3.2. Compiling kernel generation separately boot.img¶
Principle of compilation: in the kernel directory, the generated kernel.img And resource.img Replace with old boot.img, so you need to use BOOT_IMG=XXX parameter specification boot.img when compiling. The command is as follows:
cd ~/proj/RK3576_Android14.0/kernel-6.10
export PATH=../prebuilts/clang/host/linux-x86/clang-r487747c/bin:$PATH
alias msk='make CROSS_COMPILE=aarch64-linux-gnu- LLVM=1 LLVM_IAS=1'
msk ARCH=arm64 firefly_defconfig android-14.config rk3576.config
msk ARCH=arm64 BOOT_IMG=../rockdev//boot.img .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//. 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.
