Firmware Repack Tool

Note that the following operations are all performed on the PC (x86-64 architecture).

1. Install the necessary packages: sudo apt-get install lib32stdc++6

2. Download the secondary packaging tool: firefly-linux-repack

3. Unzip the secondary packaging tool:

   tar -xzf firefly-linux-repack.tgz
   cd firefly-linux-repack

   The directory is as follows:

   firefly-linux-repack
       ├── bin
       │   ├── afptool
       │   └── rkImageMaker
       ├── pack.sh # packaging script
       ├── Readme_en.md
       ├── Readme.md
       └── unpack.sh # unpack script

4. Unpacking operation: Copy the official Ubuntu firmware to the firefly-linux-repack root directory, rename it to update.img, and execute the unpacking script unpack.sh. After the unpacking is complete, the partition files are in the output directory.

   mv /path/to/ROC-RK3566-PC_Ubuntu18.04-r21156_v1.2.4a_220519.img update.img
   ./unpack.sh

5. Packaging operation: Keep the current directory structure and file name unchanged, connect the mobile hard disk to the PC, replace output/Image/rootfs.img with the Ubuntu rootfs exported earlier, and then execute the packaging script pack.sh .

   cp /media/customer/1878-4615/Firefly_Ubuntu_18.04.6_rootfs.img /path/to/firefly-linux-repack/output/Image/rootfs.img
   ./pack.sh

6. The new full firmware is new_update.img in the current directory.
