Hi friends!

I try to make a led blinking project my processor is stm32f103rg. I compile succesfully!

But it didnt work. Maybe I do some wrong configurations i don't know because (same code worked in keil and ride7)

(I attached my project below)

(I load hex file using st flash loader demonstrator.)

Regards

Hi!

i solved problem using STARTUP_FROM_RESET define using preprocessor options > preprocessor definitons

it ok.

now i want to ask one more question

this is my sample code But it doesnt go to in delayx() function or nCount variable is not working.

if i use no optimization it works else it doesnt work or if i use volatile unsigned long nCount it also work so

how will i use local wariable ?

    while(1)
    {
        GPIO_WriteBit( GPIOA, GPIO_Pin_9, Bit_SET );
        //DelayxMs(1);
        Delayx(1000);
        GPIO_WriteBit( GPIOA, GPIO_Pin_9, Bit_RESET );
        //DelayxMs(10);
        Delayx(5000);
    }

//////////

void Delayx( unsigned long nCount )
{
    for ( ; nCount != 0; nCount-- );
}

//////
