[BUG]Unable to run SWV on STM32F746 Nucleo board
Use STM32CubeIDE 1.4.2
STM32CubeMX 6.0.1
Windows 10 1903
First of all generated ioc for truestudio 9.3.
In main implement new _write function:
int _write(int file, char *ptr, int len) {
/* Implement your write code here, this is used by puts and printf for example */
for (int i = 0; i < len; i++)
ITM_SendChar((*ptr++));
return len;
}
add #define "stdio.h" in the beginning of the main.c in /* USER CODE BEGIN Includes */
in while call printf func:
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
printf("THIS_IS_NOT_WORKING");
HAL_Delay(250);
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
Enable SWV in debug configuration. Set Core clock as a HCLK in ioc file(216MHz)
And run debug. In debug open SWV ITM Data Console and enable port 0 and start trace.
(this screen from cubeide)
In truestudio everything works fine. Do the same steps in Stm32CubeIDE 1.4.2(Also generate files from zero from new ioc, because if i opened the same ioc i generated for truestudio and regenerate it for stm32cubeide, i can not build it because of errors in syscalls about reimplementation of some functions) and see nothing in SWV ITM Data Console. What am i missing???
