Freezing the IWGD Watchdog under Debug is not working

Question asked by Timo Eggers on Mar 21, 2018



i have a STM32F051 and use the independent watchdog.

I would like the IWDG counter to stop if the core is halted.

I set the DBG_IWDG_STOP in the DBG Modul, but when i stop the core with the debuger my mcu still goes in reset.


I tried setting the bit with µVision IDE, with HAL driver code and with code writing to the register directly.


Best Regards,
