hi, -
I want to make an app that in some error conditions will reset the CF (like resetting STM32 using NRF from the cflib)
searched google and found there is a command - NVIC_SystemReset() but in the CF firmware could not find that it is defined.

does anyone know if this is plausible to implement ?
if not, how would you "reset" the firmware, like what happens when there is a watchdog reset - watchdogReset() in watchdog.h
(did not exactly understand the implementation)

Thanks!!

The function NVIC_SystemReset will reset the STM32 so you can use that.

To use it, you need to include code_cm4.h since it is an inline function declared in this header file: A note about the watchdog: the watchdog resets the CPU in hardware and not in software, this is why you cannot see any software that resets the CPU associated with the watchdog.

thanks! will report if it works

tested. works.

update: after resetting, if using flow sensor, I get the message - "Error while initializing the PMW3901 sensor"

So currently I'm abandoning this method.

ah really? It works with the lighthouse deck, but we haven't tried this with the flowdeck. We will investigate this soon.

will be happy to hear if there is any update. thx!

We haven't gotten around to it.... Could you provide your app with a minimal example so that we can try it ourselves?
