DRV8301 has fault in my board

Hi all,
    Now I am transplanting from "C2000 LaunchPad XL TMS320F28027F + BOOSTXL-DRV8301 REVB" to my board.
    
The attachment is my schematic and layout, and external MOSFET is AOD444.

I use MotorWare Lab3a to do adc calibration, no modify anything. I got some questions:

Q1. DTC Resistor
  The original DTC resistor is 1 ohm, if I use 1 ohm, all input pwm(INH_A/INL_A/INH_B/INL_B/INH_C/INL_C) are strange.
  The fig1 is 1 ohm, the fig2 is 150k ohm in attachment.
  When DTC is 1 ohm, the fault is always lighting after system run.
  When DTC is 150k ohm, the fault is blinking after system run.
 
  if DTC is 150k ohm, the calibrated value are
        I_A_offset    0.7939509749
        I_B_offset    0.7900301218
        I_C_offset    0.8347318172

        V_A_offset    0.4812804461
        V_B_offset    0.4496791959
        V_C_offset    0.4856731892
 
Q2. PWM Clock
  Condition: DTC is 150k ohm.
 
  Then I run Lab2a to do parameter auto tune. In this mode, the current of power supply has overcurrent fastly.
 
 
  If I modified (in HAL_setupPwms())
      PWM_setHighSpeedClkDiv(obj->pwmHandle[cnt],PWM_HspClkDiv_by_1);
      PWM_setClkDiv(obj->pwmHandle[cnt],PWM_ClkDiv_by_1);
to
      PWM_setHighSpeedClkDiv(obj->pwmHandle[cnt],PWM_HspClkDiv_by_4);
      PWM_setClkDiv(obj->pwmHandle[cnt],PWM_ClkDiv_by_4);
      
the fault is darked, and the calibrated value are
        I_A_offset    0.8521981239
        I_B_offset    0.8434513211
        I_C_offset    0.8367571831

        V_A_offset    0.5026167631
        V_B_offset    0.4560748935
        V_C_offset    0.4990658164
      
  Then I run Lab2a to do parameter auto tune. In this mode, motor can be exciting, and rotate with low speed.
After some time, the current of power supply has overcurrent.

I don't know what happened, does anyone can help me?

Thank you.
