After setting up an Yocto build environment as described in the L4.19.35_1.0.0 BSP Yocto Project User's Guide, apply the attached patch to the meta-fsl-bsp-release layer:
<yocto_dir>/sources/meta-fsl-bsp-release$ git am eiq-sample-apps-Add-recipe.patch
To include the applications in the image, add the following line to local.conf:
IMAGE_INSTALL_append += "eiq-sample-apps"
This will include all applications from the eIQ Sample Apps repository to the built image.
