Exclude custom storage class parameters from ASAP2 generation

Hi, I created a custom storage class for my Simulink project. And ASAP2 file generation is enabled for my project.

But I want the parameters that use this custom storage class to not be included in the ASAP2 file. Is there a way to specify to exclude certain custom storage class parameters from ASAP2 generation?

Hi @Yun Han,

Starting from R2022b,

1. Open model.
2. Build model.
3. Use "coder.asap2.getEcuDescriptions" to fetch ECU descriptions in an ASAP2 file.
4. Pass the obtained description data and the parameter to be removed from the ASAP2 file into the "delete" function.
5. Generate A2L/ASAP2 file.

Sample code:

open_system("ASAP2Demo");
rtwbuild("ASAP2Demo");
descObj = coder.asap2.getEcuDescriptions("ASAP2Demo");
delete(descObj,"Characteristic","Custom_parameter1");
coder.asap2.export("ASAP2Demo",CustomEcuDescriptions=descObj);
