Just want to confirm the correct way to proceed. What I did was login to my BB-X15 in a terminal. I changed directory to /opt/source/dtb-4.14-ti/ and then I typed make and it performed the build. I did not do a, sudo make install, because I did not make any changes to the .dts files So now that I know how to do that, what is my next step when I want to make changes? Do I find the .dts file that has the I/O pins I need to change or add and then in a text editor make my changes and then build? Or is it recommended that I clone the repository over top of the files in the /opt/source/dtb-4.14-ti/ folder and then make modifications to those files in a text editor and build, doing this all on the BB-X15? Also which dts files are used by the BB-X15 and BBAI? The obvious ones are the AM57xx-bealge-x15- files but are any of the dra7 and OMAP5 files used for the BBX15? Finally if I find an I/O pin that is not set in any of the .dts files how do I determine the best file to modify to add that pin?
