Prepare build environment

To make sure the build host is prepared for Yocto running and build, please follow this guide to prepare the build environment.

Install 'repo' tool

To use this manifest repo, the 'repo' tool must be installed first

$: mkdir ~/bin
$: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo  > ~/bin/repo
$: chmod a+x ~/bin/repo
$: PATH=${PATH}:~/bin

Download Yocto Layers

The following is the step of how to use repo utility to download all Yocto layers according to the repo manifest. Replace with the real name (see Yocto branch and version below).

$: mkdir yocto-sdk
$: cd yocto-sdk
$: repo init -u https://github.com/nxp-qoriq/yocto-sdk -b <branch>
$: repo sync --force-sync

  3. How to add custom additional packages to default rootfs? Set 'IMAGE_INSTALL:append = " "' in your local.conf
