我移植的LINUX内核是2.6.14.1 板子是友善之臂的mini2440 交叉编译环境为3.4.1
在Boot options 中键入的是 noinitrd root=/dev/mtdblock2 init=/linuxrc console=ttySAC0,115200
虽然挂载上了cramfs文件系统 但是文件系统是只读的属性 无法创建路径 请问如何解决这一问题
~ # ls
bin etc linuxrc opt qt tmp var
dev lib mnt proc sbin usr
~ # mkdir tt
mkdir: Cannot create directory `tt': Read-only file system
~ #
以下是我的板子的启动信息：
VIVI version 0.1.4 (root@capcross) (gcc version 2.95.3 20010315 (release)) #0.1.
