Creating Tizen Images with MIC

This topic provides information on how to create a Tizen image.

Before creating an image, study the following instructions:

Preparing the Kickstart File

Image creation requires a kickstart file that describes how to create an image. To prepare the kickstart file:

Download the original kickstart file:

$ wget <Snapshot_date_URL>/builddata/images/<Repository>/image-configurations/<kickstart_file>

For example:

Tizen: 4.0: Unified / standard / mobile-wayland-armv7l-tm1.ks

$ wget http://download.tizen.org/releases/daily/tizen/unified/tizen-unified_20170627.1/builddata/images/standard/image-configurations/mobile-wayland-armv7l-tm1.ks

Tizen: 4.0: Unified / emulator / tv-emulator32-wayland.ks

$ wget http://download.tizen.org/releases/daily/tizen/unified/tizen-unified_20170627.1/builddata/images/emulator/image-configurations/tv-emulator32-wayland.ks

Tizen: 3.0: Wearable / target-circle / wearable-wayland-armv7l-circle.ks

$ wget http://download.tizen.org/releases/daily/tizen/3.0-wearable/tizen-3.0-wearable_20170627.1/builddata/images/target-circle/image-configurations/wearable-wayland-armv7l-circle.ks

Modify the original kickstart file to include locally built RPMs into the Tizen image.

For example: Tizen: 4.0: Unified / standard / mobile-wayland-armv7l-tm1.ks
- The repo section of the original kickstart file:
```
repo --name=unified-standard --baseurl=http://download.tizen.org/snapshots/tizen/unified/@BUILD_ID@/repos/standard/packages/ --ssl_verify=no
repo --name=base_arm --baseurl=http://download.tizen.org/snapshots/tizen/base/latest/repos/arm/packages/ --ssl_verify=no
```
- The repo section of the modified kickstart file:
```
repo --name=unified-standard --baseurl=http://download.tizen.org/snapshots/tizen/unified/@BUILD_ID@/repos/standard/packages/ --ssl_verify=no --priority=99
repo --name=base_arm --baseurl=http://download.tizen.org/snapshots/tizen/base/latest/repos/arm/packages/ --ssl_verify=no --priority=99
repo --name=local --baseurl=file:///home/<User>/GBS-ROOT/local/repos/tizen3.0-tm1/armv7l/ --priority=1
```
Note
- The baseurl property of the local repo specifies the file path where locally built RPMs are located.
- Setting the priority of the local repository at 1 and the priorities of remote repositories at 99 guarantees that MIC uses the packages that exist in the local repository with a higher priority, when packages are available in both remote and local repositories.
- To add new packages into a Tizen image, add the new packages’ names into the %package section, and add them into the local repository.

Creating a Tizen Image

To create a Tizen image:

$ gbs createimage --ks-file=mobile-wayland-armv7l-tm1.ks

If you have more than 4 GB of RAM available, use the --tmpfs option to speed up the image creation:

$ gbs createimage --ks-file=mobile-wayland-armv7l-tm1.ks --tmpfs

The following example shows the gbs createimage command output:

...

Info: Pack all loop images together to TM1-new-201609030819.tar.gz
Info: The new image can be found here:

/home/<User>/tizen/mic-output/TM1-201609030833.packages
/home/<User>/tizen/mic-output/TM1-201609030819.xml
Info: Finished.

TM1-201609030819.tar.gz is the image file and TM1-201609030833.packages contains package info integrated in the image, including package name, version, and VCS information.

Once the Tizen image is created, the final step is to flash the image to a target device for verification. For more information, see Flashing an Image to Device.
