I want to try yaffs with its emulator in /linux_tests . I ran the initnandsim successfully ,but when I try to run mkfiles ,it shows that ¡± cat /proc/yaffs_states:not exists the file or dir¡± ,and when I run mount_cycling.sh,it shows that ¡± mount :unknown filesystem ¡®yaffs2¡¯ ¡±. Could anyone help me ? and is there any simulator available? ----- Regards, Ezio
