Do you need the real-time toolbox to run external mode on S32K148EVB?

Poley — Mon, 01 Mar 2021 11:41:23 GMT

Hi,

I have received my S32K148EVB dev kit and was looking at getting external mode working.

I currently have the standard for code gen:

Matlab
Simulink
Embedded Coder
Simulink Coder
Matlab Coder

If I try and run the external example I get "Application BuildInfo does not exist: buildInfo.mat."

Is this because I don't have the right tool box or something else?

Thanks in advance!

Hello @Poley

Please have a look on this thread. You can find the instructions on how to use the external mode here:

Hope this helps,

Hi @mariuslucianand,

Thank you that made it so I can connect.

I don however get an error whist trying to change the value in the example model:

This is after I changed the constant block from inf to -1 sample time as that was also causing an error.

Thanks

Hello @Poley

You have to go to Default parameter behavior to Tunable

Additional settings that you can make can be to change the solver to "auto" you can decrease the sample time, which is now 0.1 to 0.001 to see some results on the led and to check the "Automatically handle rate transition for data transfer".

In addition, I've added a PWM signal to the Green LED.

Hope this helps,

Marius
