Hi Guys

Can you please explain to me why am I getting these serious warnings?

Serious Warning: Possible sw stack corruption, function 'Wdt_Delay_Ms' called by more than one asynchronous thread (main/Task, interrupt, interrupt low)
Serious Warning: Possible sw stack corruption, function 'FCD_LCDDisplay0_RawSend' called by more than one asynchronous thread (main/Task, interrupt, interrupt low)
Serious Warning: Possible sw stack corruption, function 'delay_ms' called by more than one asynchronous thread (main/Task, interrupt, interrupt low)

I even removed delays and replaced them with count until to try and get rid of this error but to no avail.

Regards
Xavier

Hi Xavier,
one cause is having a call macro within an interrupt macro.
Interrupt macros should be as short as possible, and be allowed to exit at the end.

Another cause is having a the same delay within a interrupt that is within a component that's not in the interrupt.

For example an LCD component(contains ms delays) within an interrupt (Not recommended)
and ms delays within a different call macro.

I would recommend ADC and LCD components being placed within a non interrupt macro.

Hope this helps.

Thanks Martin I will try doing it your way.

All the best
Xavier

Hi Martin

I have the same problem for one own macro (FCM_RC5_Tx), a PWM function (FCD_0df41_PWM1__Enable) and also the delay (delay_us).
I have 2 interrupt macros (IOC and Timer1) but in both only a counter is increased with 1.

Can there be other reasons for the stack corruption warning?

Kind regards

Hey Jan, can you post your flowcode file ?

Hi Nicolas,

The flowcode is rather complex.

Can you help me with general advices?

PS. In the meanwhile I found the source of the warning. I had an additional ASD (auto shut down) interrupt. After removing this last one, the warnings disappeared

Glad you found the error.
