    有时候,人比人强就强在搜集过滤信息的本事上,有的人黄金摆在眼前却不识,有的人愣能从泥巴里面挖出
 
黄金来,哎。。。
 
    困扰了我好几天的问题终于解决了。由于用了新的2.6.20.3内核,在进行自定义nand flash分区时仍然按
 
照以前的步骤,在devs.c中自己添加分区信息,熟不知在2.6.20.3内核在common-smdk.c中已加入了nand-
 
flash驱动,而我又在devs.c中自己定义了分区,所以出现了以下错误

这也是根据网上一位仁兄回复的一个帖子偶然得知的,我真希望知道这位仁兄时如何得知内核的nand flash
 
驱动做了如此的变化,得请教请教了。。。。
