Service Dlt_CopyRxData.

Service Dlt_CopyTxData.

Service to fo rward error reports from DET to Dlt.

Returns the Default Log Level currently used by the Dlt module. The returned Log Level might differ from the one which is stored no n volatile.

Called to request information about registered Application Ids, their Context Ids and the corresponding log level.

Returns the current Trace Status for a given tuple Application Id/ Context Id.

Returns the version information of this module.

Dlt is using the NVRam Manager and is to be initialized very late in the ECU startup phase. The Dlt_ Init() function should be called after the NVRam Manager is initialized.

The service Dlt_ Reset To Factory Default sets the Log Level and Trace Status back to the pers istently stored default values. If the feature Nv MRAM support is enabled, all stored Dlt values in the Nv M are deleted.

Indication of a received PDU from a lower layer communication interface module.

The service represents the interface to be used by basic software modules or by software component to send Log Messages.

The service represents the interface to be used by basic software modules or by software components to trace parameters.

Called to modify the pass through range for Log Messages for all not explicit set Context Ids.

This service is used to change the Log Level for the given tuple of Application ID/ Context ID.

Switches on/ off the mes sage filtering functionality of the Dlt module.

The service Dlt_ Set Trace Status sets the trace status for a specific tuple of Application ID and Context ID.

This function is called at the start of receiving an N -

Copies the current Dlt configuration to Nv RAM by calling Nv M_ Write Block().

Called after an I - PDU has been received via the TP API, the result indicates whether the transmission was successful or not.

This function is called after the I - PDU has been transmitted on its network, the result indicates whether the transmission was succe ssful or not.

Within this API , the upper layer module (called module) shall check whether the available data fits into the buffer size reported by Pdu Info Ptr - >Sdu Length. If it fits, it shall copy its data into the buffer provided by Pdu Info Ptr - >Sdu Data Ptr and update the length of the actual copied data in Pdu Info Ptr - >Sdu Length. If not, it returns E_ NOT_ OK without changing Pdu Info Ptr.

The lower layer communication interface module confirms the transmission of a PDU, or the failure to transmit a PDU.

-

The service has to be called when a software module is going to be stopped. Available vi a Dlt.h

Information about Applications

This type describes the Application Id. 0x00000000 means the so - called wildcard.

Adding or removing a Log Channel assignment for the given tuple of Application Id/ Context Id.

This is the type of the data structure containing the initialization data for Dlt.

Context Information

This type describes the Context Id. 0x00000000 means the so - called wildcard.

-

This type describes the count of arguments provided to a message.

Contains the unique Message Id for a message. This is only relevant in non - verbose mode.

-

This type describes the log lev el for each log message.

This type describes transported type of a Dlt BUSMESSAGE.

Bitfield

-

This type describes labels for trace messages.

This type describes the type of the message.

This type identifies the session.

This type describes the Log Channel name.

Service CBFidStatusChanged.

This service re-initializes the FIM.

Triggers on changes of the component failed status.

This service is provided to be called by the DEM in order to inform the Fim about monitor status changes.

This service reports the permission state to the functionality.

This service returns the version information of this module.

This service initializes the FIM.

Service FiM_MainFunction.

This service sets the availability of a function. The function is only available if FiMAvailability Support is configured as True.

This type defines a data structure for the post build parameters of the FIM. At initialization the FIM gets a pointer to a structure of this type to get access to its configuration data, which is necessary for initializsation.
