STM32 resets periodically after unplugging ST-LINK/V2

Bastien Hardy

Hello,

I'm just trying to program an STM32F103 with Keil uVision.
In-software programming and debugging work perfectly through an ST-LINK/V2, but when I unplug the ST-LINK from the STM32, the uC generates a reset about every second (maybe because it can't find the ST-LINK). I just want to use my device without the debuggger plugged-in.

Any ideas ?

Thank you.

    Looks like the hardware watchdog is enabled through the option bytes. Check the contents of the option bytes through a programmer and correct them as necessary. Or keep the watchdog enabled and service it in your firmware.
