Random Reset

[Tabulous]

Ive been getting random resets in my code, but it never gets caught in the exception handlers.........

What could cause this reset and by pass exception handlers......

A watchdog?

Try to run with the debugger attached putting breakpoints in the reset path. You need to understand if it is a reset or a random jump into the boot path.

Think i've tracked it down, its the window watchdog, inspecting the RCC to find the reset reason pointed to WWDG reset. I then traced this to a loop which was taking too long to execute, anything longer than 50ms and the WWDG will trigger......
