I tried size=256k, the result is the same, /dev can not be created successfully.

I can not image there is any reason that can cause the rootfs image
file corrupt. If it is corrupted when in build stage, the xxx.cramfs
would not be created. If it is corrupted in rootfs downloading stage,
the bootloader (mine is vivi) should say somthing.
Is there a method that can let me print debug information on the
screen before the login prompt and after the last kernel loading
message? I tried add something like
null:sysinit: .... :/bin/ls /dev
or
null:sysinit: .... :/bin/echo hello
But I see nothing.
I want to do some debug to find more information.
Again, below is my full message for you consideration:
