Storage Classes for MBDT and Freemaster

[Sam_ECU]

Hello @Irina_Costachescu 

Building of the topic here:

https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/S32k344-Simulink-program-variable-issue...

What's the recommendation for MBDT for the Signal Classes to enable tuning for Outputs, Parameters and Lookup Tables?

Regards,

Hello @Sam_ECU 

Could you please provide us more details about the use case you are trying to achieve and the encountered issues (if any)?

In this manner, we could provide specific guidance to address your scenario.

Thanks,

Hallo @Irina_Costachescu 

Step 1:

Tuning of the variables in Freemaster, but so that the signal names, parameters and lookup table names are as defined in Simulink (eg. Label, rather then Projectname.P_Label).

Step 2:

Generation of A2L file from simulink using the ASAP2 Interface with MBDT for iMXRT to allow tuning with external software such as INCA (with correct definition of addresses etc.).

Hello @Irina_Costachescu ,

For Step 1:

I've had good results with:

• Parameters / Lookup Tables: Exported_Global
• Signals: Volatile

Is there any reasons not to use these settings?

For Step 2:

The function in Matlab ">> rtw.asap2SetAddress('Project_Name.a2l','Project_Name.elf')" updates the generated A2L file from Embedded Coder with the Addresses:
