Which device?
Does it boot successfully with an official OpenWrt firmware image (release or snapshot)?

Hi mpa,

This is our product which has ipq8074 cpu and 4M SPI flash and 128M Nand flash. I have searched similar problem on google. It seems be related with mount twice rootfs. But I don't know what happen cause it. I still try to resolve this.

Thank you for your reply.
