How to interpret the displayed information? What does it mean?

Hi,

The error message indicates that an Exception happened at a RTOS Task (the ThreadType_Task) - the task is located at the indicated "Task handle" address.

The type of exception is an ARM Data Abort (the bottom message) and the program could not recover from it.

Apart from that, I will redirect this to the experts on the TI-RTOS itself, but you should be looking at things such as stack corruption, insufficient heap, un-initialized variables, buffer overruns, etc. The Runtime Object View (menu Tools → Runtime Object View) should help get additional insights.

Regards,

Rafael
