After spending a lot of days trying to make eCAP modules to read (not generate as everyone does) a PWM signal (period+duty cycle), I have to ask:
Someone has made this functionality works? Can be via sysfs, via PRU program handling the register, via CPU program handling the registers, or any other method?
If yes, can give me an example or the environment details?
PS: eCAP module is the most undocumented function of Beaglebone…
