How to check currently which PWM device is active and in which pwmchip on BeagleBone Black?
I got the ehrpwm2A PWM on P8_19 working for the current 4.1 kernel. I followed the solution posted by Kevin on google groups Here. Tested and works:). Note that while compiling the .dts on 4.1 Kernel, please use the new version of dtc i.e. DTC 1.4.1. You can upgrade to the new DTC version using Robert Nelsons BB-Overlays, even this one has been explained in the thread. Also some light has been shed on how to check which pwm device is active in this thread.
