An A2L file is a special description file that defines the implementation of an ECU. The information in an A2L file allows an XCP master to communicate with a slave module via an XCP connection. The formatted text file contains event and measurement definitions, and other configuration information, used for acquiring and stimulating data and to perform other functions.
To communicate with an XCP slave over CAN, an A2L file (ECU description file) must contain at least the following property information:
content is required if using dynamic DAQ list functionality.
Simulink®: Because the XCP CAN Data
Acquisition block uses dynamic DAQ list functionality,
Events content is
|Display A2L events list|
|Display A2L measurements list|
|Data acquisition information in A2L file|
|Name of connected slave|
|Name of referenced A2L file|
|Path of A2L file|
|Protocol layer information|
|CAN transport layer information|
