C28m35 and epwm_updown_aq_c28, no pwm output

Hello!

I am using the TMDXDOCKH52C1 with the TMDXCNCDH52C1 and I am trying to run the epwm_updown_aq_c28 example from controlSUITE.

Everthing compiles fine and it looks like it is running, but the pins are not outputting the pwm signal. It looks like the pins GPIO0-4 are floating/in input state.
What do I need to configure in the M3 programm? Is there anything else I am doing wrong?

Thank you very much in advance!

Kind regards,

Stefan

    Hi Stefan,

    Sample codes work fine and you don't have to configure anything in the code; so there might be some mistake from yourside. Please check the correct pins for pwm outs and configured pwm in the code. Check the target configuration for the correct controller. If all of this seems to be fine, delete this project and re-open the original sample project in a different workspace (please check whether its a fresh copy - untampered).

    Regards,

    Gautam
