Combine images
Usage
python mk_combined_img.py [--input <filename> --output <filename>]
The defaults of --input and --output are:
./image_configfor--input$OUT/combined.imgfor--output
Prerequisite
The script will try to get environment variables $ANDROID_HOST_OUT and $OUT
If you have built android these variables should exist and in place.
Make sure simg2img and sgdisk are in $ANDROID_HOST_OUT, if not, do following:
$ cd $ANDROID_BUILD_TOP
$ m simg2img
$ m sgdisk
Functionality
- Combine multiple images into one image with multiple partitions
- Sparse image detection
The format of input config file
Each line with the order of </path/to/image> <partition label> <partition number>
<partition number> should be within range of [1, number of lines]
and cannot be repeated.
Config file example
$OUT/sparse_system.img system 1
$OUT/encryptionkey.img encrypt 4
$OUT/vendor.img vendor 5
$OUT/sparse_userdata.img userdata 3
$OUT/cache.img cache 2
TODO
- Output in sparse format
- Detect images that already have partitions in them.
- Auto genereate config file
