STM32F103 not working SWV
Hello here,
I tried to use SWV for debug plotting in my project.
I have STM32F103TBU6 and ST-Link V2.
I turn on Trace Async Sw:
My clock:
In main.c I defined "stdio.h" and _write func:
/* USER CODE BEGIN 0 */
int _write(int file, char *ptr, int len) {
int i = 0;
for (i = 0; i < len; i++) {
ITM_SendChar((*ptr++));
}
return len;
}
uint8_t count = 0;
/* USER CODE END 0 */After I made while cycle with printf:
/* USER CODE END 0 */
/**
* @brief The application entry point.
* @retval int
*/
int main(void) {
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration--------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */
/* Configure the system clock */
SystemClock_Config();
/* USER CODE BEGIN SysInit */
/* USER CODE END SysInit */
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_DMA_Init();
MX_I2C1_Init();
MX_USART1_UART_Init();
MX_SPI1_Init();
/* USER CODE BEGIN 2 */
while (1) {
count++;
printf("Hi count=%d\r\n", count);
HAL_Delay(250);
}Setting up debug:

Pressing "Start Trace" and resume code.
And I see nothing in SWV tabs =(
What wrong in my program?
With best regards,
