STM32U575: Watchdog reset when exit from STOP3 mode.

[SMill.8]

Hello,

in my application, exiting from STOP3 mode is working fine but when the SRAM is over 192K, so getting SRAM2 addresses, exiting from STOP3 mode is forcing watchdog reset (I think when is trying to access a variable placed on SRAM2)  however from STOP2 mode is working fine.

In STM32IDE debug mode everything is working fine too, so I´m totally blind and I can´t get any clue in the reference manual.

Anyone could help me, please?

Thank you.

Hi,

it´s a .7z file, you have to rename .c to .zip to uncompress.

Anything you need to clarify, do not hesitate to ask.

Thank you very much.

Best regards.

Sorry, finally I sent files in a 7z compressed file. Forget about .c and renaming

Hello @SMill.17 

Can You please share all the project file. I'm having some declarations problems after compilation.

Best Regards.

Hello @SMill.17 

The code (core.7z) you shared is not compiling as there are many renamed pines in your original project. I did many changes to get it running. However, I can't reproduce the hardfault with the changed project. 

Can you reshare a project that reproduces the issue ? 

Best Regards
