MT7688 Boot up error

I’m having a problem relating to module linkit MT7688H. When the module boot up, I show warning
jffs2: warning: (1) jffs2_get_inode_nodes:Eep. No valid nodes for ino #234

And then, it show in console: root@(none) and cannot connect to internet or wifi.
Could you suggest me how to fix it?
