regarding the drv8829 EVM issues

* When we power on the supply for the PCB Board and trying to operate the motor in Indexer mode the Stepper Driver IC's are heating up and not able to driver the motor.

* When we try to operate the stepper motor through serial mode using the GUI of it in order to test the working conditions of the motor by different operating steps the motor will some time give the response to the parameters given and operate for only Half and quad steps and not for other steps, some times it will not give the response for any of the parameters.

Can any one please help us in this regard.

I have attached the motor spec.(Please visit the site to view this file)
