Any suggestion on how to measure the frequency of a square wave input?
Signal would be 3kHz or less. The goal is to use the appropriate AM3358
peripherals from the ARM core, not the PRU.
The eCAP peripheral comes to mind but I'm not sure it that would be
appropriate for this use case.

As far as I can tell there is no support in the Debian kernel for the eCAP
feature. You can use eCAP to output a PWM signal but I can't find anything
that supports the eCAP capture feature.

I wrote a C program that uses inotify to watch the gpioxx/value file. It
can see changes up to 20kHz, so 3kHz should be no problem at all.
