Hi, I'm testing the "Nucleo-32 STM32F303" board from st microelectronic that is compatible with NANO arduino. After configuring everything, it is correctly programmed with the arduino id by the usb and it is also programmed with the micro visual id. when i try to debug visual micro it gives me this error:

Compiling debug version of 'progtest' for 'Nucleo-32'

can you help me. Thank you
