一、XP 中安裝GiveIO 的方法

正確連接Jtag燒寫線，如果提示找不到cpu可能是插線接反。

1．首先將giveIO 文件夾下的Giveio.sys 拷貝到C:WindowsSystem32drivers 目錄下。

2．進入控制面板，點擊“添加硬件”。

3．選擇“是，我已經連接了此硬件”

4．選擇“添加新的硬件設備”，點擊“下一步”

5．選擇“安裝我手動從列表選擇的硬件（高級）”，點擊“下一步”

6．選擇“端口（COM 和LPT）”，點擊“下一步”

7．在廠商中選擇“（標準端口類型）”，點擊“從磁盤安裝（H）…”

8．在跳出的“從磁盤安裝”窗口中點擊“瀏覽（B）…”

9． 選擇當前目錄中的“giveio.inf”文件。

10． 在跳出的“硬件安裝”窗口中點擊“仍然繼續(xù)（C）”

最后點擊“完成”，結束安裝，現在可以運行ZSJF24X0.exe 來對NandFlash 進行燒寫了。

二、正常燒寫

三、bootdelay=0的解決辦法

首先我們要明確：

1. uboot燒寫地址為0x0~0x20000

2. uboot參數保存在地址 0x20000~0x3FFFF

那么我們要做的就是？擦除參數保存的區(qū)域內容，或者說是讓這個區(qū)域內容變得混亂一些。這樣uboot在加載時會提示CRC校驗錯誤，從而加載默認參數，實現我們的目的。

我的做法是將uboot.bin文件寫入這個參數區(qū)域中，實現CRC檢驗失敗的目的。

說明：起始地址是由0開始的，所以加上字節(jié)數要減1。

破解延時問題后，建議在uboot下使用命令擦除參數區(qū)域。
