挂载yaffs2文件系统的出现 devtmpfs: error mounting -2 Failed to execute /linuxrc

给力王海潮

我使用u-boot-2013.04-rc1，内核为linux3.8.3，4.4.1交叉编译器，内核的MTD分区为0-1M(uboot),1M-5M(kernel),6M-206M(file system),剩余空间为(user),板子为tiny6410，SDRAM为256M,NAND为k9GAG08U0D，yaffs2的源码是从官网上下载的，根文件系统是用busybox-1.20.2制作的，我用nfs挂载文件系统时，uboot的环境为参数为：set bootargs root=/dev/nfs console=ttySAC,115200 nfsroot=192.168.14.34:/home/wang/wang_test/rootfs ip=192.168.14.100:192.168.14.34:192.168.14.1:255.255.255.0::eth0ff  将linux内核烧写到对应的分区中，内核起来后，文件系统成功的起来了，但是我将文件系统烧写到nand对应的分区时，文件系统启动失败，这是uboot的环境参数为：set bootargs noinited root=/dev/mtdblock2 rootfstype=yaffs2 init=/linuxrc console=ttySAC,115200
出现的错误信息如下：
