CH_DBG_FILL_THREADS kills threads

Postby kdums » Wed Nov 17, 2021 5:12 pm

Hi!
Setting
#define CH_DBG_FILL_THREADS FALSE
Sets the stack pointer to 0x55555554 when stating the new task in chThdCreateStatic().
This ultimately triggers a hard fault.

CH_VERSION "2021.11.0"
Hardware is Cortex-M3

Can you confirm this?

Hi,

It is set to FALSE in all demo applications. Could you post the chconf.h that causes the exception? perhaps it is something else.

Also, compiler and compiler options?

Hi!
Sorry, obviously it's set to TRUE!
The threads stack is filled with 0x55.

Kind regards,
Klaus

Hi,

I am unable to replicate, the problem is likely it is not (only) related to that option.

Is your application using our startup files or it is a custom build setup?

Hi!

Sorry to have bothered you.
I can no longer reproduce.

Thanks for your help.

Kind regards,
