DIO Write Channel not working

beginner100 — Mon, 16 Jun 2025 21:01:45 GMT

I have an NXP S32K312 EVB and I am trying to set a pin high all the time. For this, I have followed the steps mentioned in this article - https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/Interacting-with-Digital-Inputs-Outputs-on-MR-CANHUBK344/ta-p/1746789

I want to use PTA 28 and this is how it is configured in NXPS32CT.

Here's the view of Pin configuration "Dio_Pins_MBDT" for PTA28

Also, tried setting the Initial value of Pin to High as shown in snippet

In the simulink model, I'm simply using a data store memory block to write a value of 1

I do not see the pin actually going high with this setup and config. When I measure voltage, it is about 0.13 V and also tried to probe the same pin but it always stays low. Please let me know what I could be missing. Thanks!!

Hi,

do you have Port component configured as well as article showed?
Further I can recommend to check respective SIUL2 MSCR and GPDO setting in the debugger.

BR, Petr
