I am using L6480 stepper motor driver. I have connected my board with SPIN software. If I run the motor status is shown as motor is operated. But in this case High side MOSFET's (HVGA1 & HVGB1) does not turn ON. There is no gate supply on this FET's. All other FET's are working.
Kindly help me with the issue
