I am receiving the following error message, while trying to load an A2L file.

Solution

The database is corrupted. In order to solve this you need to delete the A2L cache on your system.

Please navigate to the following path (C:\Users\USER\AppData\Roaming\TraceTronic\) and look into the subfolder of your respective ecu.test version. Inside you find data_cache_a2l.sdb.

Delete this file and try to start the configuration in ecu.test again.
