Part Number: DRV8350H-EVM

Own DRV8350H hardware can not work

Hello, everyone.

I’ve built my own hardware for a three-phase-inverter with DRV8350H. The schematic is shown.

When I test this circuit, the DRV8350H didn't work.

The supply voltage VIN is 24V. nFAULT output is 5V , but DVDD and VGLS pin output low, no Voltage difference between CPH and CPL.

How can I further dubug my device to find out the problem
