ITM Debug issue in STM32G474VET6

[Narendrasinh_D]

I am working with an STM32G474 and trying to enable ITM/SWV trace using STM32CubeIDE and ST-LINK.

Configuration

• MCU: STM32G474
• STM32CubeMX
• Debug Mode: Trace Asynchronous SW (SYS → Debug)
• Default HAL initialization generated by CubeMX

i have atteched the .ioc file .

Issue

After changing the debug configuration from Serial Wire to Trace Asynchronous SW, the application gets stuck inside:

HAL_Delay(500);

The program never returns from HAL_Delay().

Observations

SysTick_Handler() is present and contains:

void SysTick_Handler(void)
{
    HAL_IncTick();
}

However, when debugging, it appears that the HAL tick is not progressing, causing HAL_Delay() to wait indefinitely.

I found several discussions mentioning:

• Moving the HAL time base from SysTick to TIM6/TIM7
• Checking the TIM6 interrupt priority
• Ensuring the correct HAL_InitTick() implementation is used

Questions

1. Is there any known issue or required configuration when enabling Trace Asynchronous SW (ITM/SWV) on STM32G474?
2. Can enabling SWV trace affect the HAL tick source or SysTick operation?
3. Is it recommended to switch the HAL time base to TIM6 when using ITM/SWV?
4. What is the recommended CubeMX configuration for using ITM trace while keeping HAL_Delay() functional?

Any suggestions on how to diagnose why the HAL tick stops after enabling SWV trace would be greatly appreciated.

Thank you.
