stm32F407zet6 之nandflash配置后读ID死机

zhao1peng

死机的原因在调试的时候找到了  但是不知道这是哪里没配置对
HAL_StatusTypeDef HAL_NAND_Reset(NAND_HandleTypeDef *hnand)
{
  uint32_t deviceaddress;

  /* Check the NAND controller state */
  if (hnand->State == HAL_NAND_STATE_BUSY)
  {
    return HAL_BUSY;
  }
  else if (hnand->State == HAL_NAND_STATE_READY)
  {
    /* Process Locked */
    __HAL_LOCK(hnand);

    /* Update the NAND controller state */
    hnand->State = HAL_NAND_STATE_BUSY;

    /* Identify the device address */
#if defined(FMC_Bank2_3)
    if (hnand->Init.NandBank == FMC_NAND_BANK2)
    {
      deviceaddress = NAND_DEVICE1;
    }
    else
    {
      deviceaddress = NAND_DEVICE2;
    }
#else
    deviceaddress = NAND_DEVICE;
#endif

    /* Send NAND reset command */
    *(__IO uint8_t *)((uint32_t)(deviceaddress | CMD_AREA)) = 0xFF;

    /* Update the NAND controller state */
    hnand->State = HAL_NAND_STATE_READY;

    /* Process unlocked */
    __HAL_UNLOCK(hnand);
  }
  else
  {
    return HAL_ERROR;
  }

  return HAL_OK;

}


正常情况应该是运行红色部分，但是有#if defined(FMC_Bank2_3)
就不执行红色部分了，求大神告知这个宏定义要怎么修改才能将程序跳转

正点原子

不要这个宏判定可以不?
