android模拟机上不能加文件提示read only file system 是什么问题啊
mount -o remount ，rw /都试过了 ，没什么用额。

使用重新挂载还是无用

mount -o remount,rw rootfs /system/

mount -o remount,rw rootfs /system/

cd sdcard

cd sdcard

mkdir a

mkdir a
mkdir failed for a, Read-only file system

查看mounts

cat /proc/mounts

cat /proc/mounts
rootfs / rootfs ro 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
none /acct cgroup rw,cpuacct 0 0
tmpfs /mnt/asec tmpfs rw,mode=755,gid=1000 0 0
none /dev/cpuctl cgroup rw,cpu 0 0
/dev/block/mtdblock0 /system yaffs2 rw 0 0
/dev/block/mtdblock1 /data yaffs2 rw,nosuid,nodev 0 0
/dev/block/mtdblock2 /cache yaffs2 rw,nosuid,nodev 0 0
