PWM INL_C with different DTC Register

Hi all,
    I am transplanting from "C2000 LaunchPad XL TMS320F28027F + BOOSTXL-DRV8301 REVB" to my board.

The attachment is my schematic and layout(with Protel 99SE).

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

Enviroment:
  Power: DC 24V
  Motor: DC 24V, BLDC

Question:
  Once power on, the fault is always lighting on.
  I measured pwm with INL_C, it show this:



  if I changed DTC resistor to 150k ohm(10, 1k, 10k, 33k, 100k... is no effect), the waveform is:


  and sometimes it will be this. With DTC 150k ohm, the fault is twinkling.

  Other channels have the same status.

  Voltage on some test point are:
    BST_A/BST_B/BST_C               10.48V
    SHA, SHB, SHC                   0.5V
    DVDD                            3.3V
    AVDD                            6.5V
    VSENS                           0.8V
    IA_FB                           1.68V
    IB_FB                           1.67V
    IC_FB                           1.67V
    DV_V_FB                         2.98V
    GVDD                            11.0V
    CP1/CP2                         11.3V

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

thank you
