Introduction.
AUTOSAR-Dcm Configuration Explained.
In this article, the configuration code of Dsd will be explained.
Let me show you the configuration code of Dsd.
As the class diagram was simple, the code is also simple.

};AUTOSAR-Dcm Dsd configuration code explanation
There are quite a few lines, but they are not complicated.
As you can see, UnProtected_SecurityList and ALL_SessionList are not defined in this.
This is a list of security levels and sessions, but the entities are in Dsp, not Dsl.
Therefore, the entity does not appear here, only by reference this time.
I’ll let you be prepared for this part when I explain Dps.
(Next article is the Dsp, though….)
Conclusion
- I wrote the configuration code for Dsd.
- The corresponding security level and session entity are in Dsp and only referenced from Dsd.
