For the imx8qxpmek evaluation board, I built yocto project for bsp release L4.19.35_1.1.0. Then, I invoked following command to extract toolchain:
DISTRO=fsl-imx-xwayland MACHINE=imx8qxpmek bitbake core-image-minimal -c populate_sdk
A new folder is created in build/tmp/deploy/sdk
Inside sdk folder, there is filename: fsl-imx-xwayland-glibc-x86_64-core-image-minimal-aarch64-toolchain-4.19-warrior.sh
I copied this script to /opt folder. Then, I executed this script to install sdk. I chose to have sdk installed in build/mysdk folder. Inside mysdk folder, there is environment setup script: environment-setup-aarch64-poky-linux. I ran this environment setup script.
I believe next step is to compile? How do I build binary image that can be deployed in the target?
