    新购买的两套的七寸触屏TQ2440套装,原系统是Linux的,但我需要使用WinCE6系统,我是用配套光盘中的七寸文件下的镜像:
路径:..出厂烧录镜像合集\群创7寸屏的镜像\WinCE

  安装好打开SecureCRT软件和TQBoardDNW软件。
  第一步:由于有Libux变为wince,先格式化。选择开关拨到Nor Flash下,打开SecureCRT,打开电源,进入UBOOT模式,选择9,然后选择y,回车:
          Enter your selection: 9

         NAND scrub: device 0 whole chip
         Warning: scrub option will erase all factory set bad blocks!
         There is no reliable way to recover them.
         Use this command only for testing purposes if you
         are sure of what you are doing!

         Really scrub this NAND flash? <y/N> : y
          Erasing at 0xa140000 --  63% complete.
          NAND 256MiB 3,3V 8-bit: MTD Erase failure: -5, bad block at 0x0a2a0000.

         NAND 256MiB 3,3V 8-bit: MTD Erase failure: -5, bad block at 0x0a2e0000.
        Erasing at 0xffe0000 -- 100% complete.
        OK

第二步:选择1,选择2,选择b,分别选择对应STEPLDR、EBOOT、LOGO文件,运行结果分别为:

第三步:关闭电源,拨到Nand Flash位置,激活SecureCRT,按住PC的空格键,然后启动电源,
然而开发板背光量了一下,屏幕没反应,而SecureCRT软件上只输出:
  ECC ERROR block0x00000004page0x00000009
  
  然后多次关闭电源,按空格,开启电源,串口调试都是蹦出同样信息:
  ECC ERROR block0x00000004page0x00000009
  ECC ERROR block0x00000004page0x00000009
  﨓CC ERROR block0x00000004page0x00000009
  鳨CC ERROR block0x00000004page0x00000009
  麰CC ERROR block0x00000004page0x00000009
  鳨CC ERROR block0x00000004page0x00000009
  
  两个板子结果都是一样。是我的步骤有问题?还是怎么着?请帮忙。

2440烧写镜像用的都是下载工具的uboot菜单

我都用的uboot下载,所以1,2,b都显示成功的。nand下打开电源,却不出现eboot界面,没法烧NK

问题搞定,原来是贵方发的光盘中镜像和板子不兼容,技术支持发了新的镜像就烧写OK了
