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.
There is another possibility: you may have enabled the boot loader at power up (the BOOT pins). If so, the boot loader will keep resetting with a 1-second timeout, IIRC.
That did the trick, it was an hardware issue.
Thanks a lot for your help !
