STM32L471RG HardFault

[Dorina]

Hi Mikroelektronika Team,

Am using Mikro C Pro ARM v6.0
I have problem with mcu STM32L471RG.
My test code is very simple, I only want to blink a LED on port PortC bit13.
Here is my code:


sfr sbit LED at GPIOC_ODR.B13;

int i;
void main()
{
GPIO_Config (&GPIOC_BASE,
_GPIO_PINMASK_13,
_GPIO_CFG_MODE_OUTPUT | _GPIO_CFG_SPEED_MAX | _GPIO_CFG_OTYPE_PP);
Delay_ms(100);

while(1)
{
i++;
if (i > 500)
i = 0;
LED = 1;
Delay_ms(500);
LED = 0;
Delay_ms(500);
};
}


I can't run this code... when I debugging I have the following error message :
HardFault [IPSR=3]
at line 0x04EA 0xE7FE B L___GenExcept28


Here is my oscillator settings:
RCC_CR : $40021000 : 0x00000B60
RCC_CFGR : $40021008 : 0x00000001
RCC_PLLCFGR : $4002100C : 0x00000800
RCC_CSR : $40021094 : 0x00000600
PWR_CR1 : $40007000 : 0x00000200
-HSI16 Oscillator in use without PLL

I have checked power supply and other signals with scope, VDD/VSS VDDA/VSSA, Reset Signal and BOOT0 pin...its all OK.
I have also attached the screenshots of HardFault and oscillator settings.

How can I solve this problem?

Thank You.

Hi,

First of all, I apologize for the delayed reply

This seems like a complicated issue thus taking this long to solve, as it affects other families as well.

As soon as I have a solution I will contact you.
