NUCLEO-U083RC SWV issue

[chris84]

Hi,
I got an issue where I can no longer activate SWV Viewer option inside debug configuration for my NUCLEO-U083RC board. The SWV checkbox is greyed out. 
Whether I create a new project or load an existing one, the SWV option is greyed out and can no longer be selected. 

Anyone got an idea what is going on?
Also I had some issues with ITM_SendChar as it would not compile. 

Debug Trace Asynchronous Sw is active. On Nucleo board I assume SWO is connected. 

Cube IDE 1.17.0.
STM32U0 V1.2 package.

Hello @chris84 ,

 SWV is not available for the Cortex-M0, that is why the button to enable SWV option is greyed out.

Try to use Live Expressions if you want to check a specific variable for example.

Hi @Imen.D 
thank you very much for quickly shed light on it. 

The fact that in Cube MX under Debug I still can activate SWO as Trace Asynchronous Sw was misleading for me.

Thanks you. Chris
