STM32CubeIDE 在没有调试信息或程序代码之外的地址“xxx”处中断

Question

I'm busy bring up some new hardware with a STM32F030C8 mcu. I'm using the STM32CubeIDE with gcc. I'm very new to microcontroller development and this is my first project with ST and their tools.

This is a very basic program that just triggers a GPIO. The rest is all generated code. As I have very little experience in this field I hope somebody can point to a location where I can look. I suspect that it might be a configuration issue.

Here is the code (I removed all generated comments to keep it a bit more compact):

int main(void)
{
  HAL_Init();

  SystemClock_Config();

  MX_GPIO_Init();

  HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_2); //my code 1
  HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_2); //my code 2

  while (1)
  {
      HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_2);
      HAL_Delay(1000);
  }
}

When I step through the code It will trigger the GPIO on "my code 1" once I step to "my code 2" it will cause the issue. I have even tried just running a fully generated program with no modifications and the issue persists. This was a quick test to see if the program actually does run on the mcu. And it does, as well as trigger the GPIO.

Debugger console Output:

Temporary breakpoint 1, main () at ../Core/Src/main.c:74
74        HAL_Init();

Program received signal SIGTRAP, Trace/breakpoint trap.
0x1fffecec in ?? ()

The Temporary breakpoint is where the program starts, I can then either run from there. Or step through, all with the same result.

Console Output:

Full Error:

Break at address "0x1fffecec" with no debug information available, or outside of program code.

Here is two images that might help. As I mention I'm very new to this. So any other information required please ask. Thanks in advance.

The code is placed at 0x08000000. There is no user code at 0x1fffecec. It system area and probably it boots the system bootloader. It shows that the BOOTx pin is incorrectly connected.
