VAR-SOM-MX7 Toolchain installation for out of Yocto Krogoth builds

VAR-SOM-MX7 - Yocto Krogoth toolchain installation for out of Yocto builds

Assuming you followed steps 1, 3, 4 & 5 of the Build Yocto from source code guide, as an example of X11 build, build the toolchain by:

$ cd ~/var-imx-yocto-krogoth
$ MACHINE=var-som-mx7 DISTRO=fsl-imx-x11 source var-setup-release.sh -b build_x11
$ bitbake meta-ide-support
$ bitbake meta-toolchain

The output will be located at tmp/deploy/sdk/. On a 64 bit Ubuntu you will get the following script.

Install the tools by running it:

$ tmp/deploy/sdk/fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa7hf-neon-toolchain-4.1.15-2.0.1.sh

The toolchain name depend on your build machine and may change.

Each time you wish to use the toolchain in a new shell session, you need to source the environment setup script:

$ source /opt/fsl-imx-x11/4.1.15-2.0.1/environment-setup-cortexa7hf-neon-poky-linux-gnueabi
