Overview of Memory Page Manager

The INCA database contains several projects that in turn contain datasets including working and reference datasets.

An electronic control unit (ECU) typically has two pages: a working page and a reference page. These pages are assigned to the current workspace via the Hardware Configuration Editor or the Database Manager.

In principle, the INCA concept mirrors the ECU data in the database meaning that the ECU data working dataset and the reference dataset exist in both the ECU and the INCA database.

Reference page (dataset)	+	Working dataset (dataset)
Reference page (ECU)	+	Working dataset (ECU)

The functionality of the Memory Page Manager (MPM) consists of copying the data in all directions supported by the ECU. The actions provided are therefore derived from the ECU description file. The integrated flash tool is used according to the memory type concerned. Other actions for managing the current memory pages are also provided.

A device list shows all the ECUs of the current hardware configuration, including the status of the checksum calculation.

During the first hardware initialization, the contents of the datasets in the database are often newer than the contents of the electronic control unit. During hardware initialization, if different checksums are calculated in the INCA datasets and the corresponding ECU datasets, or if the checksum can not be calculated, Memory Page Manager is started automatically.

The datasets with the different checksums are underlaid red in the checksum display. Furthermore, Memory Page Manager is set so that you can load the corresponding datasets directly from INCA into the electronic control unit without having to make any further settings in the Memory Page Manager.

Unnecessary checksum calculations, for example, if you conduct measurement tasks only without making changes to the calibration values, can be prevented in the Hardware Configuration Editor in the settings for the device concerned. Additionally, you can cancel any checksum calculation manually.

You can start the Memory Page Manager at any time from the Hardware Configuration Editor and from the Experiment Environment.
