RKCfgTool

This tool allows you to extract the contents from the cfg file generated by RKDevTool, and also allows you to create a cfg file that can be read by it.

Features

• Cross-platform, open source and free.
• Completely reliable reading from or writing to cfg file.
• Convert between cfg files and json files at will.
• Generate cfg file directly from parameter.txt, support automatic scanning of available image files.
• Use the command line to manipulate cfg files.

Usage

Usage: rkcfgtool [--help] [--version] --input VAR [--output VAR] [--show] [--enable-auto-scan] [--set-auto-scan-prefix VAR] [--remove-partition VAR]...

Optional arguments:
  -h, --help              shows help message and exits 
  -v, --version           prints version information and exits 
  -i, --input             Import a file. [required]
  -o, --output            Set the output file path (if any). 
  -s, --show              Print the partition table information contained in the cfg file. 
  --enable-auto-scan      When converting  parameter.txt to cfg file, the image file in the current directory will be automatically scanned and applied. 
  --set-auto-scan-prefix  Add a prefix to the results of the automatic image_path scan, will add a slash at the end (if not already there). Example: './Output' [nargs=0..1] [default: ""]
  --remove-partition      Remove all matching partitions from the input. Syntax: '(address|name|image_path|index):..., example: 'name:userdisk'. [may be repeated]

For example, We have the following directory structure:

$ ls
boot.img  MiniLoaderAll.bin  misc.img  parameter.txt  recovery.img  rootfs.img  trust.img  uboot.img

parameter.txt contains the partition table information, which comes from the general format of rockchip and looks like this:

FIRMWARE_VER: 8.1
MACHINE_MODEL: RK3326
MACHINE_ID: 007
MANUFACTURER: XXXX
MAGIC: 0x5041524B
ATAG: 0x00200800
MACHINE: 3326
CHECK_MASK: 0x80
PWR_HLD: 0,0,A,0,1
TYPE: GPT
mtdparts=rk29xxnand:0x00002000@0x00004000(uboot),...,-@0x0123a000(userdisk:grow)
uuid:rootfs=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Now, we can create a cfg file that can be read by RKDevTool directly with the following command:

./rkcfgtool -i parameter.txt -o test.cfg --enable-auto-scan

--enable-auto-scan will automatically scan all files in the same directory as parameter.txt, and fill in the image_path field if the partition name may match a file.

If you need to delete some partition from the result(take userdisk as an example), use the following command:

./rkcfgtool -i parameter.txt -o test.cfg --enable-auto-scan --remove-partition "name:swap" --remove-partition "name:userdisk"

Furthermore, add a prefix to the result path of the automatic scan:

./rkcfgtool -i parameter.txt -o test.cfg --enable-auto-scan --set-auto-scan-prefix "./Output" --remove-partition "name:swap" --remove-partition "name:userdisk"
