I'm a noob when it comes to changing kernels and device trees. I have no idea on how to start. So far I've downloaded device-tree-compiler.

I want to change a USB dr_mode to "peripheral". I want to do this because I reached out to the company that designs the board I am working on and told me to change just one line from this file..https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_4.9.x_2.0.0_ga/arch/arm/boot/dts/imx6qdl-hp.dtsi#L1009

I've read some articles talking about device trees, but I need to know 1. how to locate it 2. how to edit it 3. how to run it.

I'm kinda just learning this on my own.

Thanks in advanced!
