- The #embedded standard #AUTOSAR Adaptive enables more powerful and flexible in-vehicle E/E architectures. This #tutorial focuses on the following topics:
Vehicle diagnostics adapts to Adaptive environments. We show you new possibilities: Multiple software clusters with their own diagnostic address. And: several diagnostic testers simultaneously through conversations. Also: The interface to the application: ara::com as well as tips on configuration & workflow.

Thanks Mr. Wigbert Knape for this wonderful session.
I am little confused when we talk about UDS in slide 8. Should we use 0x34 Request Download, 0x36 TransferData and 0x37 Transfer exit services here or any other UDS service?
Another question I have is Whether Diagnostic Service Application is same as UCM Client described in the Autosar document?
Thank you for that interesting question. You are right, the UDS services 0x34/0x36/0x37 are indeed used to transfer the data. The UCM itself is independent from UDS, the SDA interacts with UDS.
The SDA is different from AUTOSAR UCM. The SDA is a manufacturer specific software that contains all the business logic and processes to ensure the manufacturer specific aspects of the update (e.g. package signature checks).
@@vectorinformatik "UCM Client is used to cover both roles:Diagnostic Application and OTA Client." This is from Autosar Specification of UCM.
UCM has two parts UCM platform service and UCM Client. AUTOSAR specification talks about two types of UCM clients: Diagnostic Application and OTA(Over The Air) client.
@@vectorinformatik If we use 0x34/0x36/0x37 for downloading of the data, What would be the memory address for 0x34 Request?
The UDS 0x34/0x36/0x37 are implemented in Diagnostic clients right? How can we connect Diagnostic client and UCM then?
@@godwincharan We think it is helpful to continue this discussion in a direct way. You can reach our expert Wigbert Knape at "embedded@vector.com". Thank you for your interest!
