Problem with System_reset and watchdog

[Nils Minor]

Hi,

i have some trouble with my watchdog in application. If i does a System_reset (no SD Method because i disabled it before) it sometimes top at this point and does nonsense. What reason could it have that this method hangs the application? And i have enabled the watchdog and did a pin reset so it is running, why does the watchdog not kill the running application when its hanging?

Best regards Nils Minor

Based on your description, it's almost impossible to say anything. Have you been able to halt the chip with a debugger when this hang occurs, to see exactly what it's doing and where it hangs? I'm not aware of any issues that could cause problems like what you describe.
