Read inside the AM335x datasheet about eCAP module. It's basically
copy-paste from TI DSP's, so you can find on web some examples about
configuration of the registers for the DSP - you'll need only to change
the memory offset.
1 - enable eCAP module (clock, etc) writing correct registers
2 - set the pin mux - you can use linux shell for that
3 - configure eCAP registers

You can use the Pulse-Width Modulation Subsystem (PWMSS) for that,
chapter 15 in datasheet od AM335x Sitara Processor
You can write / read registers using devmem2
Remember to enable L4 clock before
Thanks for your answer.
Is there any project I can have a look at to understand how things work?
I'm new to BBB/PRU, and I have to admit that it is not easy to use...
Maybe there are some libs/modules available?
