I build the imx-image-full. I was able to get the wifi, and bluetooth up and running by executing the commands described here https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/How-to-use-Bluetooth-on-i-MX8M-boards/ta...
What I want now is to enable them from yocto. Meaning when the image is build. Once you flash it. then it will already have the wifi and bluetooth and GPIO up and ready to go. I'm not sure on how to convert/create/append a recipe to enable all of that.
