有人用过K9F1208U0A-YCB0这个块FLASH吗?

我第一次用求帮啊！为什么擦不了啊！

u32 FSMC_NAND_EraseBlock(u32 PageAddress)
{
   uint32_t data = 0xff, status = NAND_ERROR;
  *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_ERASE0;   //0x60
  *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(PageAddress);  
  *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_4th_CYCLE(PageAddress);
          
  *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_ERASE1;  //0xD0
    while( GPIO_ReadInputDataBit(GPIOD, GPIO_Pin_6) == 0 );
    FSMC_NAND_GetStatus();
    data = *(__IO uint8_t *)(Bank_NAND_ADDR | DATA_AREA);
    if(!(data&0x01))
    {
            status = NAND_READY;
    }
  return (status);
}
