HAL_Delay() not working on STM32F103ZET6 (LED Blinking Example)

[Helmish]

I am using a stm32F103ZET6 to just blinking a led but the HAL_Delay() is not working.

I change the HAL_Delay() with for loop and it work.
this is the code that i am using :

while (1)

{

HAL_GPIO_WritePin(Led_301_GPIO_Port, Led_301_Pin, 1);

HAL_Delay(500);

//for (int i=0; i < 500000; i++);

HAL_GPIO_WritePin(Led_301_GPIO_Port, Led_301_Pin, 0);

//for (int i=0; i < 500000; i++);

}

}

I want to work with HAL_Delay because i need to use it in a project with this mcu

Hello,

Did you configure the GPIO pin? The GPIO clock?

Could you share your project?

[Helmish]

this is the project.

[mƎALLEm]

In your attached project: you're toggling correctly the pin PA8:

	 HAL_GPIO_WritePin(Led_301_GPIO_Port, Led_301_Pin, 1);
	 HAL_Delay(500);
	 //for (int i=0; i < 500000; i++);
	 HAL_GPIO_WritePin(Led_301_GPIO_Port, Led_301_Pin, 0);
	 //for (int i=0; i < 500000; i++);
	 HAL_Delay(500);

I don't see any issue in your project.

What do you mean by "HAL_Delay() is not working"? what is the symptom?

Need two delays otherwise it loops immediately and turns on/off too quickly to see

[mƎALLEm]

Set a breakpoint in HAL_IncTick() in SysTick_Handler() interrupt handler:

void SysTick_Handler(void)
{
 /* USER CODE BEGIN SysTick_IRQn 0 */

 /* USER CODE END SysTick_IRQn 0 */
 HAL_IncTick();
 /* USER CODE BEGIN SysTick_IRQn 1 */

 /* USER CODE END SysTick_IRQn 1 */
}

Are you reaching it?

I can't debug because I haven't any debug solution

[mƎALLEm]

Seems you're executing the code from the SRAM (you didn't mentioned that important information) but it overlaps with r/w data and with VTOR. That's why the Systick interrupt (used by HAL_Delay) is not working

You need to rethink/rework your project.

[Helmish]

Can you please explain this. What do you mean by rethink/rework

Also i have to add some information.

I change the flash memory in the file .std from 512ko to 484ko and the start address from 0x8000000 to 0x8006000. Because in the project specification i have to do that.
