各位：
      有没有谁成功用ULINK下载程序到STM32外挂FLASH？我下载时提前示FLASH超时出错。谢谢！！

芯片为K8P3215，FSMC现在的情况是，能读不能写。FSMC配置为：
_WDWORD(0xA0000000, 0x00005059);   // FSMC config for test
_WDWORD(0xA0000004, 0x10001008);   // FSMC config   
_WDWORD(0xA0000104, 0x10001008);   // FSMC config
写FLASH的如下：
for (i = 0; i < ((sz+1)/2); i++)  {
    /* Start Program Command */
    M32(base_adr + (0x555)*2) = 0x00AA;
    M32(base_adr + (0x2AA)*2) = 0x0055;
    M32(base_adr + (0x555)*2) = 0x00A0;
    M32(adr) = *((unsigned long *) buf);
    if (ToggleAlgo(adr)) return (1);    /* Wait until Programming completed   */
    buf += 2;
    adr += 2;
  }
