Thank you to reply actually i am using System workbench IDE so when I give command to flash the micro controller then it is showing such error.
I will share you screen shot of it.
Below is my code:-
/**

#include "stm32f30x.h"
#include "stm32f3_discovery.h"
int main(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOE,ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9|GPIO_Pin_8|GPIO_Pin_12;
GPIO_InitStructure.GPIO_Mode= GPIO_Mode_OUT;
GPIO_InitStructure.GPIO_OType= GPIO_OType_PP;
GPIO_InitStructure.GPIO_PuPd= GPIO_PuPd_NOPULL;
GPIO_InitStructure.GPIO_Speed= GPIO_Speed_50MHz;
GPIO_Init(GPIOE,&GPIO_InitStructure);
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA,ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
GPIO_InitStructure.GPIO_Mode= GPIO_Mode_IN;
GPIO_InitStructure.GPIO_OType= GPIO_OType_PP;
GPIO_InitStructure.GPIO_PuPd= GPIO_PuPd_DOWN;
GPIO_InitStructure.GPIO_Speed= GPIO_Speed_50MHz;
GPIO_Init(GPIOA,&GPIO_InitStructure);
for(;;)
{
GPIO_SetBits(GPIOE,GPIO_Pin_12);
if(GPIO_ReadInputDataBit(GPIOA,GPIO_Pin_0))
{
GPIO_ResetBits(GPIOE,GPIO_Pin_9);
GPIO_SetBits(GPIOE,GPIO_Pin_8);
}
else
{
GPIO_ResetBits(GPIOE,GPIO_Pin_8);
GPIO_SetBits(GPIOE,GPIO_Pin_9);
}
}
}
In attachment highlighted area is by which I will flash my program into MCU.
