resetting an STM32F

obdgenie obdgenie

I'm looking for a way to do a soft reset on a STM32F207. I'm not able to find or compile any of the watch dog examples, I can jump to absolution location but not execute, and most other code samples I find are missing the supporting functions. What is a simple method to reset the chip?

    Does is work with HAL? When I include core_cm0 I get a slew of errors with missing identifiers.

    Why would you include core_cm0 ?

    The STM32F207 isn't a Cotrex-M0 - is it ?

    I net reference. Yes should be core_cm3

    but I still get the same errors

    So you've just pulled-in the core_cm3 file without paying attention to what other stuff it depends on

    No, I just had my STM32F2XX included elsewhere. Forgot to add it to this file. Works thx!
