Beagle Entertainment System device tree builder for 3.14-ti kernel
This tree contains device tree definitions extracted from the Linux kernel source tree. It was originally forked from the 3.14 branch of:
https://github.com/RobertCNelson/dtb-rebuilder
Use the "build.sh" script to create the device tree files used for BES. The "clean.sh" script will clean up the source tree and delete any .dtb files in the "deploy" directory. Once you have built the .dtb files:
-
Run the "build.sh" script to create the various BES .dtb files. Each .dtb file has a particular display configured for it, so select the .dtb file in "deploy" that matches the display you want to use. Your choices are the built-in HDMI cape and the various LCD capes: CircuitCo LCD3/4/7 and the 4DSystems 4DCAPE-43T/70T.
-
Backup the dtb/am335x-boneblack.dtb file in the /boot partition of your BES microSD card.
-
Copy the BES .dtb file that you wish to use to the /boot partition of the microSD card as dtb/am335x-boneblack.dtb.
When you boot the BES system with the new .dtb, you'll have the following features in your system:
-
Display support for the display option you selected.
-
GPIO button inputs for SNES controller 1 on P8.7 through P8.19 (in bes-gpio.dtsi).
