关于STM32通过FSMC控制NAND FLASH的COPY-BACK命令使用问题

是否解决:

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());
}
