# Vedi descrizione. Può essere risolto?

Quando riavvio il target (STM32 MCU con ST-Link) nel mezzo del debug, IAR non riesce a recuperare - semplicemente smette di rispondere.

In general, debuggers will lose their connection when the target power is lost. Also if the CPU goes to sleep. when you power up device so IAR workbench need your device id to respond you are doing power cycle so yor debug code is not clean in your board and it blocks device connection path to send target board's device id to iar software via st-link utility
