各位大侠，我在这个论坛的lumit4510项目里学习。国庆期间，我在lumit4510的S3c4510板子上移植了uClinux with Kernel 2.6.9,并且
加入了自己的NAND Flash的支持，希望最终能用这个Nand Flash作为
根文件系统。但是现在还有一些问题，所以到这里来向各位请教，希望大侠们
不吝赐教！谢谢！！
目前状态：
1.uClinux with kernel 2.6.9已经能成功跑起来
2.我甚至换了Romfs,改用NFS方式来作为Rootfs。(弄这个好辛苦，折腾半天)
3.已经能够检测到NandFlash,并且已经可以分区，可以eraseall /dev/mtd0.
4.JFFS2 on Nand Flash还存在问题。不太清楚具体在哪里！
下面是我dump的信息：
