I could yes, but I read somewhere (can't remember where exactly, but it was in some TI PowerPoint presentation that reading the eCAP register takes at least 4 cycles, which is not ideal for my purposes. In the meantime I found a way to use the BBB built in PWM as a CLK signal and it works now. Check this link <https://www.teachmemicro.com/beaglebone-black-pwm-ubuntu-device-tree/> if you're interested. Thanks for your help nonetheless.
