A quick guide for downloading and building Yocto 1.6 "Daisy" for i.MX6 platform:
mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
PATH=$PATH:~/bin
mkdir fsl-community-bsp && cd fsl-community-bsp
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b daisy
repo sync
source ./setup-environment build
bitbake core-image-minimal
The default target machine is "imx6qsabresd", but you can change it from conf/local.conf file.
