TIDA-01606: TMS320F28379D

Hi Expert

I just start developing TIDA-01606, this is not the 1st time 1 debug the program, i am using C2000 Launchpad TMS32F28379D, i compile build = 1 (open loop inverter mode)

the problem 

1. The PWM (EPMW1,EPWM2, etc) register didn't updated especially the Compare Register and Timer Counter, seems the timer not configured properly or not triggered

I am using code that TI provided in TIDA-01606

I try debug the duty cyle via dummy variabel, i am confident that duty value cyle already there but its not translated to PWM hardware.

I found subroutine that update the PWM value but, no PWM output

 I also try to look in oscilloscope but nothing signal was produced

Please help, i also double check that PWM source pin was correct, the PWM pin should at GPIO 0~4 & GPIO 4~6 & GPIO 12~15 on schematic

I am pretty sure this is software problem

Thank you very much
