Just updated kernel to 4.4.31-ti-r67. now i can find position and period in the /sys/devices/platform/ocp/48304000.epwmss/48304180.eqep/
but cat position keeps returning 0. when trying to use other pins: config-pin P8_33 qep and config-pin P8_35 qep it returns invalid mode qep the same in P8_41 and P8_42 ... have anyone tried it? is it working? I am not sure if it is not working or if i am looking wrong pins or my encoder doesnt work ok... My encoder middle pin is hooked to GND and the other two pins in eqepA and eqepB respectively.
