The debugging issue in STM32WL55CC still not fixed in current STM32CubeIDE release 1.14

[asydhom]

Hi,

I am trying to debug both cores in STM32WL55CC chip. When trying debugging CM0+ i get error. I am using STM32CubeIDE ver 1.14.1 and also tried STM32CubeIDE ver 1.8 per a suggestion in older post, both don't work.

The followings are the configurations and error I am getting. 

M4 running under debug:

and now starting M0 under debug:

 

 

 

M4 code is indeed running but debugger seems preoccupied with it and won’t share the resource for M0 debugging.

Thanks.

Hello @asydhom 

Sorry for my late replay. I've escalated your issue to the Concerned team for more investigation and correction if there is an error (under internal ticket number 182777).

Hello @asydhom 

I suggest that you take a look at the Application note AN5564. It highlights some of the points to bear in mind while debugging a device in the STM32WL Series. Knowing that I made a STM32 project using NUCLEO-WL55JC1, and I ran the debug session of the Cortex M4 and M0.

Best Regards.
