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.

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.
