For now, if I have HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI); somewhere in the main loop, any printf() call leads to jumping to the 0xdeadbeee address and windows “frame not in module”. Without going to STOP mode everything works perfectly. Using “normal” semihosting just prevents CPU from entering the STOP mode. Thank you, Alexander.
