How to build Yocto SDK and compile for i.MX
The first step is to create the Yocto SDK. After building an image (e.g. bitbake fsl-image-gui), build the Yocto SDK using the command:
$bitbake <image name\> -c populate_sdk
$bitbake fsl-image-gui -c populate_sdk
Bitbake will build all packages to create the sdk and also the sdk installation script. This script will be located at:
Execute this script Without adding ‘source’ or ‘. ./’ before the script. Just execute like in this example:
$cd tmp/deploy/sdk/ $./fsl-imx-fb-glibc-x86_64-fsl-image-gui-cortexa9hf-neon-toolchain-4.1.15-2.0.1.sh
The following message will be displayed asking the installation path to install the SDK. If you agree with the path, just press enter:
Enter target directory for SDK (default: /opt/fsl-imx-fb/4.1.15-2.0.1): You are about to install the SDK to "/opt/fsl-imx-fb/4.1.15-2.0.1". Proceed[Y/n]? Extracting SDK............................done Setting it up...done SDK has been successfully set up and is ready to be used.
Now SDK is already installed. Just execute the environment-setup script using ‘source’:
All environment variable to build new programs for i.MX will be exported. Just use make to build for ARM.
