TIDA-01606: TMS320F28379D——LAB6

hello

   I am currently running Lab 6 (E6 revision) and have encountered an issue.After strictly following the steps in the reference manual, I set TINV_startPowerStage = 1; immediately afterward the flag  fault_iGridA_overCurrent becomes 1 and stays latched. Setting TINV_clearPwmTrip = 1 does not restore PWM operation.From the source code I understand that asserting TINV_startPowerStage only enables the current loop at the next voltage zero-crossing. Could you help explain why the over-current trip is nevertheless triggered at this instant? In your experience is the root-cause more likely to lie in the current-sense path (AMC1306M05) or in another part of the circuit?
