k9f1g08读id
typedef struct
{
  u8 Maker_ID;
  u8 Device_ID;
  u8 Third_ID;
  u8 Fourth_ID;
}NAND_IDTypeDef;

void FSMC_NAND_ReadID(NAND_IDTypeDef* NAND_ID)
{
  u32 data = 0;

  /* Send Command to the command area */
  *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = 0x90;
  *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00;

   /* Sequence to read ID from NAND flash */
   data = *(vu32 *)(Bank_NAND_ADDR | DATA_AREA);

   NAND_ID->Maker_ID   = ADDR_1st_CYCLE (data);
   NAND_ID->Device_ID  = ADDR_2nd_CYCLE (data);
   NAND_ID->Third_ID   = ADDR_3rd_CYCLE (data);
   NAND_ID->Fourth_ID  = ADDR_4th_CYCLE (data);
}
