The package MICROSAR Classic XCP supports XCP communication with an XCP master on various communication topologies such as CAN, CAN-FD, LIN, FlexRay or Ethernet. The runtime environment MICROSAR Classic RTE supports software components with calibration ports allowing access to calibration data. MICROSAR Classic RTE manages calibration data access during offline and online calibration; the latter supports different data access strategies like initialized RAM and Single- and Double Pointered. Configuration (e.g. transport layer parameters or XCP events) is done in the configuration and generation tool DaVinci Configurator Classic (formerly DaVinci Configurator Pro).
