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
Note
To avoid unnecessary errors, please do not unzip the SDK in shared folders, mounted folders or non-english directories.
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

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-userdebugAfter 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.
Build outputs
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 |

Generate the incremental OTA package
Generate a new base material package
The v1.zip basic material package has been made, and another v2.zip material package needs to be made to generate the difference package. You need to modify the kernel DTS code or Android code, and then run the command again.

Some Introduction about Compiling
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.
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 -j8After compiling, boot.img in the kernel directory can be directly upgrade.

./FFTools/mkupdate/mkupdate.sh -l rk3588_firefly_aio_3588q-userdebugIn the rockdev/Image-rk3588-firefly-aio-3588q/ directory, find the corresponding firmware and burn it to the machine, then the machine can carry out the full package upgrade and the difference package upgrade,put 'update.zip' into /sdcard/ and restart the full package as prompted.
Generate the incremental OTA package
Generate a new base material package
The v1.zip basic material package has been made, and another v2.zip material package needs to be made to generate the difference package. You need to modify the kernel DTS code or Android code, and then run the command again.
./FFTools/make.sh -d rk3588-firefly-aio-3588q -j8 -l rk3588_firefly_aio_3588q-userdebug -oRegenerate a new base material package that we can copy.
cp out/target/product/rk3588-firefly-aio-3588q/obj/PACKAGING/target_files_intermediates/rk3588-firefly-aio-3588q-target_files-eng.xxx.zip ~/ota/v2.zipGenerate the incremental OTA package command

Put update.zip to the machine sdcard directory reboot, it will automatically recognize, and then click the steps to complete the upgrade.

Refer to OTA Documentation to setup the sever.
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-rk3588_firefly_aio_3588q/ 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/RK3588_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-rk3588_firefly_aio_3588q/boot.img rk3588-firefly-aio-3588q.img -j8After compiling, boot.img in the kernel directory can be directly upgrade.
