Part Number: TMS320F28377S

Hello：

At present, several cases of DSP defects have been found in the energy storage machine of the customer's factory, which are

GOIP20 GPIO21 is configured with PWM11A and 11B, and cannot output PWM signals normally. Please assist us in investigating the cause. thanks！！！

    Hi Jimmy, 

    To have more context, could you please describe what the expected output of PWM11A and PWM11B should be based on your PWM settings and what signal output are you seeing that is incorrect? Is it that there is no PWM signal being output on both GPIO20 and GPIO21 at all? Or is it that you are getting PWM signals, but they are incorrect? And to clarify, is the signal on the left image being held low or high?

    Best regards,

    Allison
