The Meaning of CANoe Error: System 17-0020
The DoIP diagnostics interpretation can only be performed either for the legacy Diagnostic over IP/HSFZ diagnostic access (i.e without option Ethernet) or for Ethernet. As soon as Ethernet channels are configured in the Simulation Setup, diagnostics interpretation of DoIP messages can exclusively be done based on the CDD that has been added as diagnostic description for Ethernet as diagnostic access. To avoid this error message, you need to move all diagnostic descriptions from the legacy Diagnostic over IP/HSFZ diagnostic access to one or more Ethernet networks.
Depending on your configuration, it might also be necessary to reassign the access for the setting Enable diagnostics via DoIP/HSFZ gateway for this network from (DoIP) to one of the Ethernet networks in the configuration dialog of the Ethernet diagnostic access.
