关于K9F1208芯片的COPY-BACK功能求解

uaremyfuture

本人使用STM32F103ZET7，通过FSMC总线控制NAND FLASH 芯片K9F1208，能够正常读、写、擦除以及读取状态等，但是在COPY-BACK这个功能上遇到了问题，貌似无法复制数据。我的代码如下，麻烦哪位大神遇到过这个问题赐教一下：

uint32_t NAND_CopyBack(NAND_ADDRESS SourAdd, NAND_ADDRESS DestAdd)
{
    *(__IO uint8_t *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_AREA_A;

    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00;
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_1st_CYCLE(ROW_ADDRESS(SourAdd));
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_2nd_CYCLE(ROW_ADDRESS(SourAdd));
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(ROW_ADDRESS(SourAdd));

    *(__IO uint8_t *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_CPYBAK;
   
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00;
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_1st_CYCLE(ROW_ADDRESS(DestAdd));
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_2nd_CYCLE(ROW_ADDRESS(DestAdd));
    *(__IO uint8_t *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(ROW_ADDRESS(DestAdd));
   
    *(__IO uint8_t *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_WRITE_TRUE1;
   
    return (NAND_GetStatus());
}

参看这个芯片的手册，是不是命令或者操作顺序有错，没有用过这个功能，帮顶。

感觉并没有什么问题，命令代码也是对的，关键是最后的状态检测时Pass了的
