TMS570LS3137: MCAL ICU & GPIO pin is not working as configured

Part Number: TMS570LS3137

I am facing below issues related to ICU module & GPIO. Please support in resolving these,

  1. I have configured the PINs 23, 36, 38 as ICU input pins. I am testing these pins using signal generator  but could not see the signal changes getting reflected when reading the pin values.
  2. I have configured Pin 97 as digital output and trying to set this pin high and low, but could not observe any state changes in the pin.

    Hello Lakshmikanth,

    In order to use ICU, you need to configure NHET, and add channels for ICU. Can you please post your configuration files and EB generated files used in your CCS project?

    I noticed that the thread is the same as the previous one, so I will close this one. Thanks
