==Concept of binary repository==

[[MIC]] image creator can create image from so-called '''binary repository''', which can be stored at Web or even on your own PC.

The '''binary repository''' is the directory that has the following structure:

[[File:Repos-structure.jpg|1100x700px|center]]

The XML files contain metadata necessary for work with the repository.

==Creating local repository that can be used with MIC==

First you need to have mic and createrepo to be installed on your PC. If not, follow the guide described on this page: [https://source.tizen.org/ru/documentation/developer-guide/installing-development-tools?langredirect=1 Installing development tools]

"createrepo" is the utility that generates the metadata necessary for a RPM package repository: primary.xml, other.xml and so on. To install it, run the following command:

 sudo apt-get install createrepo

Create the directory where you will store your local repository:

 mkdir /home/user/my-repo
 cd /home/user/my-repo

Create one directory for each architecture that will present in the repository:

 mkdir aarch64
 mkdir noarch

Download RPM packages from the repository published by OBS server:

 cd aarch64
 wget -r -l1 --no-parent -nd -nv -A "*.rpm" http://download.tizen.org/live/devel:/arm_toolchain:/Mobile:/Base/aarch/aarch64/
 wget -r -l1 --no-parent -nd -nv -A "*.rpm" http://download.tizen.org/live/devel:/arm_toolchain:/Mobile:/Main/aarch/aarch64/
 cd noarch
 wget -r -l1 --no-parent -nd -nv -A "*.rpm" http://download.tizen.org/live/devel:/arm_toolchain:/Mobile:/Base/aarch/noarch/
 wget -r -l1 --no-parent -nd -nv -A "*.rpm" http://download.tizen.org/live/devel:/arm_toolchain:/Mobile:/Main/aarch/noarch/

Download files '''group.xml''' and '''patterns.xml''' from some official Tizen repository and save them into special '''repodata''' directory:

 cd /home/user/my-repo
 mkdir repodata
 cd repodata
 wget -r -l1 --no-parent -nd -nv -A "group.xml" http://download.tizen.org/releases/daily/tizen/mobile/latest/repos/mobile/ia32/packages/repodata/
 wget -r -l1 --no-parent -nd -nv -A "patterns.xml" http://download.tizen.org/releases/daily/tizen/mobile/latest/repos/mobile/ia32/packages/repodata/

Run the generation of repository by '''createrepo''' utility:

 createrepo -g /home/user/my-repo/repodata/group.xml --database --unique-md-filenames /home/user/my-repo

Add file '''patterns.xml''' under the control of the repository:

 modifyrepo /home/user/my-repo/repodata/patterns.xml /home/user/my-repo/repodata

After that you can use directory '''~/my-repo''' as the local MIC repository via '''*.ks''' files using the following line:

 repo --name=mobile --baseurl=file:///home/user/my-repo --save --ssl_verify=no

And then you may run mic for firmware creation

 sudo mic -i create loop -A aarch64 /home/user/my-repo/repodata/fw.ks --shrink --runtime native
