Calling a function by it's address not working

[NNar]

Using a STM32F0 discovery board, I have this function:

void BlinkBlue(void)
{
	for (int i=0; i<20; i++)
	{
 		HAL_GPIO_WritePin(LD4_GPIO_Port, LD4_Pin, GPIO_PIN_SET);
 		HAL_Delay(50);
 		HAL_GPIO_WritePin(LD4_GPIO_Port, LD4_Pin, GPIO_PIN_RESET);
 		HAL_Delay(50);
	}
}
 

and I can call it in code by using:

BlinkBlue();

All good.

The .map file says it's location at address 0x8000a9c . But it doesn't work if I instead call it using:

((void (*)(void))0x8000A9C)();

Any idea why this wouldn't work? Thanks.

Thumb code uses an ODD address, ie 0x08000A9D

Perhaps try printf("%p\n",&BlinkBlue);

This solved it. Thanks!
