I want to use the code generation feature, but I'm getting an errors:Invalid memory section 'code_ramfuncs' specified in the Subsystem Parameters dialog of block 'FOC_SI_PMSM_Init_Position/FOC Alogorithm/Current Control'. No memory section package selected in the Configuration Parameters dialog.How can I fix this?

@朴子生 could you share your model so that I can reproduce the issue at my end, thanks!

Hi @朴子生,

The memory section "code_ramfuncs" or "ramfuncs" or const_data_ramfuncs" comes from the TI C2000 custom-storage-class package tic2000demospkg that ships with the TI C2000 Support Package.

As I checked the Subsystem Parameters dialog of block 'FOC_SI_PMSM_Init_Position/FOC Alogorithm/Current Control', I found the "Memory section" settings set to "Default" :

This means it is not mapped to "code_ramfuncs". There can be two workarounds to solve this:

1. You can change it to "Inherit from model" , this will make the code run from flash not RAM. If this doesn't work then you can try the second method.

2. Go to your subsystem "FOC Alogorithm" and navigate here as shown below:

In the "Embedded Coder Dictionary", go to "Memory Sections" and click on "Manage Packages" and select tic2000demospkg and click on "load". You will see "code_ramfuncs" appear now in the list, you can click on save as shown:

Now if you go back to block parameters of 'FOC_SI_PMSM_Init_Position/FOC Alogorithm/Current Control', you can see the "code_ramfuncs" option in the drop-down as shown:
