A simple MATLAB DIO example can't load into the board (S32K3X4EVB-T172)

alimaknouni · ‎10-07-2025

Hello,

I just purchased a S32K3X4EVB-T172 EVal board. I tried to run the example "code s32k3xx_dio_s32ct". It compiles correctly, though, can't load into the board. The same board I could make it work with a simiular example directly from NXP DS.

I also changed the Hardware part to "S32K344-Q172". It is the same. It gives the error "Runtime error 216 at 6BEBA7AE". Then the following message:

And this log:

"

Could you please help me what is wrong, and how I can make it right?

Hello,

The error you get is due to the fact that MBD Toolbox for BMS is working only with MBD Toolbox for S32K3 1.4.x version. It is not compatible with S32K3 1.7.0 version.

To solve that error, you can do the following:

1. Do a backup of the modified examples (if any) from the toolbox.

2. Uninstall all toolboxes, on both MATLAB R2025a and MATLAB R2024b.

3. Modify the addons default installation path for each MATLAB version you have installed. Please use a short name and without whitespaces. It must be unique for each MATLAB version you have.

e.g.: MATLAB R2024b default path : "C:\MATLAB\Addons\Toolboxes\R2024b"

MATLAB R2025a default path: "C:\MATLAB\Addons\Toolboxes\R2025a".

To change the default installation folder follow these instruction:

4. Install again the NXP MBD Toolboxes you need for each MATLAB version.

In your case, the problem is that both MATLAB version have the same installation folder and even though you installed a toolbox in a R2024b, it is also available in R2025a. The S32K3 1.4.x checks for other S32K3 toolboxes and it detects that the 1.70 is installed, hence the error.

Let me know if this solution fixes your problem.

Best regards,

Sorin Bancila

Hi Sorina,

I followed your advise. Deleted all the MATLAB installations and add-ons, all the folders created, and did a clean install from beginning. Also selected the add-on folder a short path on C:\ . It resolved the above incompatibility issue.

Thanks,

Ali

Hi Dragos,

I'm using MATLAB R2024b, with NXP add on 1.4. I tried NXP add on 1.7 at first, but the MATLAB example codes do not work with 1.7. It asked me to downgrade to 1.4. So did I.

My NXP DS is ver 3.6.1.

I appreciate your help.

Thanks,

Ali

Hi,

Firstly, please ensure that there is only one toolbox in your MATLAB path—the one you intend to use. This helps prevent potential issues where files might be inadvertently loaded from an unintended toolbox.

Secondly, could you please elaborate on what you meant by saying that the example codes do not work with version 1.7.0? This will help us better understand the issue you are reporting.

Best regards,

Dragos

Hi, @alimaknouni,

Could you please let us know which versions of the toolbox and MATLAB you are currently using, so we can attempt to reproduce the error on our side?

Additionally, we have recently released a new version of the S32K3 toolbox, version 1.7.0. If you are not already using it, we recommend upgrading and trying to download the code to the hardware board again.

Best regards,

Dragos

Hello,

I don't know why my previous replies are not posted here.

I'm repeating.

I have installed MATLAB R2025a with add on 1.7, and MATLAB R2024b with add on 1.4.

If I try to open any MATLAB NXP example with MATLAB 2025a, add-on 1.7, I get the following error.

Actually, if I just ignore this and continue running the code, it will compile, and even load into the MCU and run correctly!

Could you please clarify with this? Can we focus on resolving this? For now, I will continue using the embedded coder with this alarm until we find what is going on.

Thanks,

Ali
