大家帮忙啊！

再擦除整个芯片，重新写CFE。命令：C:\JTAG\brjtag.exe -probeonly /nompi /erasechip

按照楼上的命令。出现以上提示！

以前都没有出现这样的错误，如果接线没有接好的话。

没人帮忙？还是大家给一个判断啊！

4#不是已经给你建议了吗？ 按照4#链接里的方法加电，或许还能救回来，不知道你是否尝试过。
你的设备目前flash ID检测不到， 但访问地址却是1E000000,这说明曾经刷入的CFE已经对6358进行了部分初始化，否则全空状态下访问地址应该是1F000000.
4#链接方法是个通用方法，并不只限於新设备，其他出现flash ID检测不到，不能进入debug模式的都可以照此办理。
最坏的情况是flash损坏，只有换芯片一条路。

软件输出的信息绝大多数都是有意义的，最好帖完整，否则提供的信息太少，很难进行判断

growing 发表于 2009-11-19 11:27:06

我有认真去看你的帖子，但是我发现我的问题不是你描述的那样啊！
我输入命令以后出现的提示，我在上面的帖子都有贴出来。我再贴出来吧

因为我的问题不是挂住的问题！

且OE#引脚接地的方法要怎么做？用到什么设备？

还是有些不懂，望H大给予完整的解答！！！万分感谢！
