DRV8353RS-EVM: GDF error troubleshooting

Hi Team,

Can you help me troubleshoot the customer issue regarding GDF?

The customer use DRV8353Rx-EVM with InstaSPIN_F2802xF_UNIVERSAL to drive a motor but it does not work. The fault LED is always on. 

I asked them to check the Fault status and the results shows problem with the gate drive:

 The customer is feeding the EVM with 48-60V supply and no modification has been done. 

I asked them to provide scope shots for GLB, GHB, GLA, GHA and ENABLE and below is the result:

The enable pin goes high when the fault LED is on. Can you help diagnose the issue?

Thank you.

Regards,

Marvin
