Hi Try to download the code once and compile again, in my case the code is working correctly.

Freestyler or Lumikit

The project still needs a lot of work, the project is open source so you can work on the project and improve it too.

My test code and cpu clock  while (1) { ITM->PORT[0].u8 = 0xaa; status ^= 1; HAL_GPIO_TogglePin(LED_GPIO_Port,LED_Pin); ITM->PORT[0].u8 = 0xbb; HAL_Delay(1); }

Var Viewer OK 

Trace Viewer not work

Yes, this is fine, without this setting Var Viewer probably wouldn't work either. 

I have not tried to check that, I will try to connect the oscilloscope to the SWO pin today and let you know if there is any data on the...

I found that I have no data on the SWO pin. Please check my .ioc file if everything is set correctly. [STM32H743_STMViewer_Test.zip](https://github.com/user-attachments/files/15943841/STM32H743_STMViewer_Test.zip)
