LMG34XX-BB-EVM: R9 burned out

Part Number: LMG34XX-BB-EVM
Other Parts Discussed in Thread: LMG3410EVM-018


I am using LMG34XX-BB-EVM with LMG3410EVM-018. DC input 300V, 12V isolated dc input and no load at the output(just a multimeter). I am using LaunchXL28379D for PWM input.(Using only one PWM input, deadtime generated in LMG34XX-BB-EVM)

I made a couple of attemts, worked fine for a while. I followed steps SNOU165A pg14 5.2 startup and 5.3 Shutdown procedures. At the last attempt when HV is ON, R9 exploded, no fault signal.

R9 burned out, you can refer to pictures below. Any ideas?

Thank you
