STM32H747-DISCO SWV Trace issue

Hi,

I want to use SWV to profile my application which executing on CM7 core while CM4 core is disabled as it is shown on first figure. Before I start profiling I want to check if SWD work at all and I execute this command:

ITM_SendChar('a');

but i cant see any logs in SWV ITM Data console.

I setup everything in debug interface as it shown on second picture. On third picture is presented Serial Wire Viewer setting and I think that it is also configured well. Does anyone have idea what is a problem?
