Hi Aniket,
There are a few items to try.
First remove the motor and confirm the device is operating as expected. The voltage on the outputs will change as the step is advanced.
Next please provide the VREF voltage and sense resistor value used.
Also please try fast decay if using slow or mixed decay.
If you can send a scope capture of the current waveforms that would help. If not, send two scope captures. The first is the STEP input with AOUT1, AOUT2 and AISEN. The second is the STEP input with BOUT1, BOUT2, and BISEN.
