根文件系统烧写和程序运行错误

xingma0910

直接将开发板通过nfs挂载到服务器上，使用服务器上的根文件系统，是可以正行运行的。而且我将cramfs文件系统烧写到开发板中，先用nfs挂载，启动成功后输入：

mount  -t  cramfs  /dev/mtdblock3  /mnt/test

挂载后进入到/mnt/test目录中进行操作，我自己的程序是可以运行成功的。但是为什么当板子启动后，我直接使用开发板上的根文件系统，运行程序会有错误呢？

我的bootargs设置：

setenv bootargs 'noinitrd root=/dev/mtdblock3 rw  rootfstype=cramfs init=/linuxrc console=ttyS0,115200, nolock mem=40M'

还请帮帮忙看看。谢谢！这个问题已经困了我好多天了，一直没有进展。

出错信息贴出来看看

arm-linux-gcc

完整的启动log贴出来


另外noinitrd root=/dev/mtdblock3 rw  rootfstype=cramfs init=/linuxrc console=ttyS0,115200, nolock mem=40M
你没有设置单位吗？

怎么都没人帮帮忙啊！这个问题还木有解决。

这种问题得具体问题具体分析了，帮不了你
