Tutorials on Setting Up device tree in Yocto for routing GPIO to Pins

[mitchponv]

Good afternoon,

I have been looking everywhere and I cannot find a tutorial or any instructions on how to configure the Yocto kernel to mux any of the GPIOs in Linux to physical pins on Imx6.

This should be a very basic entry level introduction on how to work with the Yocto SDK, and should provide step by step instructions

I currently have a Yocto installation from this tutorial: Yocto Project Quick Start

And an Imx6 Hummingboard

If someone can please help such tutorial, I would greatly appreciate it.

Thank you,
