Run-Time Library Built Automatically

By default, BullseyeCoverage automatically compiles and adds the run-time library run/libcov-ti.c to compiler invocations that link an executable. This source implements the small footprint configuration. You can override this behavior by including in your link command your own run-time library named with the prefix libcov-, for example libcov-userDefined.a.

The covc option --lib cannot be used with the TI compiler.

Saving Coverage

Add a call to cov_dumpData into your program. When using the Code Composer Studio simulator, the data file appears in the configuration directory, for example Debug\BullseyeCoverage.data-1. 

#if _BullseyeCoverage
    cov_dumpData();
#endif

Run Under Debugger

The BullseyeCoverage run-time source file for TI Code Composer, BullseyeCoverage/run/libcov-ti.c, calls the low level POSIX-style functions provided in the TI Code Composer run-time. When running under the debugger, these operations are performed according to the host's operating system.

BullseyeCoverage run-time error messages are written to standard error. After starting the debugger, use the command View Console so that you can see any error messages that might occur.
