无法加载文件系统

silencexf

我的ucLinux启动代码如下，感觉文件系统加载错误，映像包括内核和ROMFS两部分，BootLoader采用U-BOOT 1.1.3,请各位大侠指点迷津。

应该是内核编译的问题
以前编译的时候也经常出这个问题

silencexf

能准确说明与内核编译的哪些选项有关吗？遇到这种问题你是怎么解决的？

silencexf

原来问题已经解决，又产生新的问题
Blkmem: bad access: block=0, count=2 (pos=400, len=0)
end_request: I/O error, dev 1f:00 (Blkmem), sector 0
romfs: unable to read superblock
Kernel panic: VFS: Unable to mount root fs on 1f:00
可能的原因是什么？

lumit-support-1

你有能用的uClinux吗? 最好能在能用基础上进行修改,那样可能还比较容易

kurthq

你最好用winbond自带的bootload比较简单

你好，我也是用的W90N740，不过我用的是从 uclinux.org 上下载的 uclinux-2.4.31. 我的uclinux 网络，系统都是正常的。就是 usb 口挂载优盘以后，对优盘进行写操作的时候会死系统。不知道有谁解决了这个问题？？？

人在旅途

用华邦提供的BSP就好，对大部分u盘都可以支持。
