Code coverage measurement on real hardware target

Could you please share your idea about the measurement code coverage that is run on actual hardware target? It's mean how to do instrument for that test and the method how to get the coverage information after testing code is executed on real hardware.

Example: I have STM32L152RB discovery board. I do the Unit testing for its software. I can run the code coverage measurement on X86 (Visualizing environment or PC environment). But I want to run that testing code on real hardware (STM32L152RB discovery board) to make sure that the code coverage is more reliable.

Thanks and regards, TRUONG
