I have a stm32L476G-DISCO.
trying to get this simple blink led program working.
CODE:
while (1)
{
HAL_GPIO_TogglePin( LD_G_GPIO_Port, LD_G_Pin );
//(LD_R_Pin);
HAL_Delay(2000);
/* USER CODE END WHILE */
MX_USB_HOST_Process();
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */

Hello @Kt.1,
Welcome to ST community .
This a debugger problem. Please check the cable you are using and make sure that you have correctly configured the Debug Configuration and connected to the ST-Link on the board.
If you are using STM32CubeIDE, I recommend you checking the 3rd section of the STM32CubeIDE User Guide.
Chahinez.
