我是想测试芯片能否正常烧录程序，自己在转接座周围搭了简易电路，程序是用的探索者F407的例程（修改了Device和IO口）
程序如下：

#include "sys.h"
#include "delay.h"

void LED_Init(void)
{
  GPIO_InitTypeDef  GPIO_InitStructure;

  RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9 | GPIO_Pin_10;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

GPIO_SetBits(GPIOA,GPIO_Pin_9 | GPIO_Pin_10);

}

int main(void)
{

delay_init(168);
LED_Init();

while(1)
{
GPIO_ResetBits(GPIOA,GPIO_Pin_9);
GPIO_SetBits(GPIOA,GPIO_Pin_10);
delay_ms(5);
GPIO_SetBits(GPIOA,GPIO_Pin_9);
GPIO_ResetBits(GPIOA,GPIO_Pin_10);
delay_ms(5);
}
}

能下载成功但是对应引脚没有波形输出，已试过多个IO口；
想请教一下大家我是哪里弄得不对，谢谢！
