Hercules launchpad issue with pwmSetDuty

Other Parts Discussed in Thread: HALCOGEN

Hello everybody, excuse me if this is to silly to post here or if I am missing something trivial, I am quite newbie to Hercules launchpad.

I am taking my first steps with Hercules TMS570LS04x/03x launchpad evaluation kit, I've already gone through some of the basic examples provided in the HalCoGen examples folder. Now I want to control 2 hobby servos modifiying one of their duty cycles with a button, while reading 3 adc channels and send these values to a terminal.

In HalCoGen I configured the GIO, SCI, ADC and HET drivers, set pwm signals pwm1 and pwm2 to 20ms of period and 7.5% duty cycle in order to command the servos to middle position, selected adc channels 0, 1 and 9 of the ADC1 Group1 and compiled in HalCoGen.

In code composer I basically took the adc example code and added the button and pwm duty cycle. I have no problems with the adc conversion and displaying data and the pwm signals are ok with the initial HalCoGen setting but I can't modify the pwm duty cycle with pwmSetDuty function, moreover, after some attempts of changing duty cycle by hitting the GIOA7 button on the launch pad, the data from the adc no longer display.

This is the code I tried:

I'm stuck so any help is appreciated
