DRV8302 Gate Pin output waveform is abnormal

DRV8302 Gate Pin output waveform is not a normal square wave but a triangular wave.

It always happens in Phase A,and Phase B\C are normal.

I exchange the gate driver and it'll get normal but when I use it for a while,The same problem will happen.

I have changed the Firmware of the VESC so I'm not sure whether it is caused by hardware or software.
