DRV8825 Problem

HI,

I am using DRV8825 for driving stepper motor, whose specifications are, 1.5A, 1.43ohms, Fs = 110RPM.

When i am driving the motor, motor gets stuck at start only and if i rotate shaft by hand it starts rotating.

I tried acceleration curve, with different micro stepping and frequencies, but same issue :(

What is the reason for such behavior?

Also is it necessary to give some pulses at initialization of Driver IC?

Thank you .
