在TQ2440使用手册的V2.5版本的4.2章节烧写Linux部分讲解了这样的错误的原因的。你可以看一下。
http://bbs.embedsky.net/viewthread.php?tid=859&extra=page%3D1这里可以下载这个教程。

我按照天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf
上的step1~step12 一步一步做完了

不是TQ2440使用手册

还请说下具体的解决方法。

请教大家该问题。

几次都是这样。。。。。
没有人知道吗？

还是那个步骤需要注意，我按照手册一步一步做的。

我也出现过这样的情况
但我也没解决，正等待高手指教呢
不好意思
