Hello,
I am fairly new to the C2000 / CCS environment and I have a problem with enabling profiling.
I am trying to enable the -gen_profile_info for my code and I get the linker error below. It looks like the RTS library needs to be instrumented as well but I am not sure how to achieve that.
I am using TMDSDOCK28379D (F28379D Experimenter kit) with CCS v6.2.0.00048 Beta for MAC OSX.
