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  <font color=red>Attention:
To avoid unnecessary errors, please do not unzip the SDK in shared
folders, mounted folders or non-english directories.</font>

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

Core-3576JD4 product compilation method

The overall compilation

HDMI Firmware Compilation

   ./FFTools/make.sh -j8 -l rk3576_firefly_aio_3576_jd4-userdebug
   ./FFTools/mkupdate/mkupdate.sh -l rk3576_firefly_aio_3576_jd4-userdebug

Step by step to compile

Compile the kernel:

   cd ~/proj/RK3576_Android14.0/kernel-6.1
   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_3576_jd4/boot.img rk3576-firefly-aio-3576jd4.img -j8

Compile uboot:

   cd ~/proj/RK3576_Android14.0/u-boot/
   make rk3576_defconfig
   ./make.sh --spl-new

Compile Android：

   cd ~/proj/RK3576_Android14.0/
   source build/envsetup.sh
   lunch rk3576_firefly_aio_3576_jd4-userdebug
   make installclean
   make -j8
   ./mkimage.sh

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_3576_jd4-userdebug

After packaging, it will be in rockdev/Image-
rk3576_firefly_aio_3576_jd4/ 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.

Some Introduction about Compiling

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/Image-
rk3576_firefly_aio_3576_jd4/ directory.

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-6.1
   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_3576_jd4/boot.img rk3576-firefly-aio-3576jd4.img -j8

After compiling, "boot.img" in the kernel directory can be directly
upgrade.

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-rk3576_firefly_aio_3576_jd4/. The following lists the
image files used by general firmware:
