对这两个分区我也很不解,不知道 uboot和kernel是怎么放的?
也不知道文件系统烧写到什么地址,试用34800000这个地址,运行时出现上面问题.
是我的文件系统没有烧写对地址吗?还是什么别的原因?
谢谢!

提供一个解决流程
1. 先看uboot先init的参数。
2. 看flash分区，看地址是否设置错误。
3. 看启动脚本里面inittab设置。

没仔细看，先分析下，问题不大。

文件系统内部的问题

[dongjiawei316]

载文件系统时出的问题，很可能是你自己所说的，文件系统放的位置和你在uboot里写的位置不匹配。

8M nor flash.

bootargs=mem=32M console=ttyAMA0,115200 busclk=135000000 root=1f01 rootfstype=jffs2 mtdparts=phys_mapped_flash:1536K(boot),6656K(rootfs)

uboot代码中:
#define MEM_BASE_FLASH 0x34000000

linux启动时打印:
Creating 2 MTD partitions on "phys_mapped_flash":
0x00000000-0x00180000 : "boot"
0x00180000-0x00800000 : "rootfs"


mtd分区是通过mtdparts参数分配的两个区,我怎样确定文件系统烧写地址?

[blueviss]

起始位置是Uboot的，你的定义是从0x34000000开始
内核位置从0x34100000开始
文件系统应该是从0x34200000开始
