板子上引导linux失败
板子放着有几天没碰了，原来的wince里面有东西，老师招呼过不要冲了。对板子操作又不熟悉，一直没敢动。今天又向那边打听了下引导双系统，又发来一份资料，就又折腾了下。烧写应该是成功了，但却引导不起来，总是说挂载不了根文件系统
具体过程如下，记录下来，再想办法解决
Please select function :
0 : USB download file
1 : Uart download file
2 : Write Nand flash with download file
3 : Load Pragram from Nand flash and run
4 : Erase Nand flash regions
5 : Write NOR flash with download file
6 : Set boot params
7 : Set AutoBoot parameter,1:linux 2:wince
1 //选择1 从串口下载 选择好内核文件
Now download file from uart0...
Download File Size = 632566
Are you sure to run? [y/n] //选择不运行 要烧写
Please select function :
0 : USB download file
1 : Uart download file
2 : Write Nand flash with download file
3 : Load Pragram from Nand flash and run
4 : Erase Nand flash regions
5 : Write NOR flash with download file
6 : Set boot params
7 : Set AutoBoot parameter,1:linux 2:wince
2Read chip id = ec76 //选择2 烧到Nand flash
Nand flash status = c0
Please select which region to write : Esc to abort
0 : offset 0x0 , size 0x40000 [boot]
1 : offset 0x40000 , size 0x1c0000 [kernel]

5 : offset 0x2000000 , size 0x2000000 [ext-fs3]
Now write nand flash page 0x200 from ram address 0x30400000, filesize = 632560
Are you sure? [y/n] // 烧写kernel 选择1 并确定 y
.......................................Program nand flash partition success

最后就是不能挂载根文件系统。 所有的操作都是照资料给的做的 wince是保存在 第 5 区的 所以wince还是正常的。 再去请教下吧 如果有朋友知道 还望指点下````
