Hi, @Alfredo_Rubio ,
I highly recommend you check out the Release Notes of the latest release, version 1.5.0. I will summarize the new approach between Port and Pins:
The toolbox offers support for configuring the on-board pins using the Port component, from the Peripherals Tool, together with the Pins Tool. The two must be used together as required by the implementation of the RTD (Real-Time Drivers) package that MBDT integrates. The configuration of the pins must be made according to the following information:
For each functional group inside the Pins Tool, a Port container must be configured inside the Port component. Please see the screenshots below, the first one taken from the Pins Tool, and the second one from the Port component configuration inside the Peripherals Tool of a .mex file.


By inserting the PortPin Mscr inside the PortPin configuration, the settings inside the Port component for that particular pin will be automatically populated as configured inside the Pins Tool. The name of the Pins Tool functional group must respect the following convention: PortContainer Name + ‘_MBDT’, ‘MBDT’ representing the name of the Functional Group from the Peripherals Tool, where all the components of the project are configured.
Please check one of the default configurations provided inside the toolbox for an example on how Port and Pins must be configured.
Additionally, you can find information related to Pins and Port tab in S32 Configuration Tool at the following Community thread link.
Please let us know if you have other issues.
Best regards,
Dragos
