Starts a FreeRTOS task to run CoreMark benchmark.
See EEMBC for more details.
Between parenthesis result with -O0 for comparaison, otherwise -O3 is used to compile Coremark.

You may adjust CoreMark settings in CoreMark configuration else simply exit.
Number of iterations should not be too long to avoid watchdog error.
You will need to build afterward.
