Kernel 2.6.9 on lumit4510 .
这几天没干别的，就搞它了！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：

很希望搞过JFFS2的高手指点一下，已经快到了，却总是不出来！好郁闷！ 换了Romfs,改用NFS方式来作为Rootfs,这个东西具体怎么操作？能否说个大概？ 换了Romfs,改用NFS方式来作为Rootfs,这个东西具体怎么操作？能否说个大概？
