Could anyone point me to some resources that explain how to write device tree files for the BBB?
To clarify, the OS running on my BeagleBone is a custom Linux distro (not one of the more common Debian or Angstrom ones). The current configuration only enables one of the SPI ports and none of the PWM pins. I want to modify the .dts file used in building the OS so that it correctly enables and muxes the SPI and PWM pins that I select. I also want to avoid using device tree overlays, so I’m dealing with just the device trees. Any help would be appreciated, thanks.
