I am currently utilizing an STM32G431KB board that differs from other boards in the STM32 Nucleo series as it has a wired SWO. While setting up SWV printf on a Nucleo variant of the same product, I encountered an inquiry and implemented suggestions given by its first answer which allowed me to enable functioning SWV under C programming language.
However, upon switching over to C++, no output is visible during usage of this feature.

For the C project, I created a new project, switched Debug to “Trace Asynchronous SW,” and added the following code:

“`c
/* USER CODE BEGIN Includes */
#include “stdio.h”
/* USER CODE END Includes */

/* USER CODE BEGIN 0 */
int _write(int file, char *ptr, int len)
{
int DataIdx;
for (DataIdx = 0; DataIdx < len; DataIdx++) { ITM_SendChar(*ptr++); } return len; } /* USER CODE END 0 */ ``` In the main loop, I added: ```c /* USER CODE BEGIN 2 */ int i = 0; /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { printf("%d Hello World!\n", ++i); /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */ ``` Upon activating SWV in the Debug Configuration, adjusting the core clock to 170 MHz, deactivating timestep in SWV settings and empowering port 0; executing C yields optimal results with expected output. On renaming `main.c` to `main.cpp`, the project operates in C++, but there is no result. What could be the reason for this problem?
