Intel Apollo Lake Android Marshmallow Question

Hi,

I read document '571613_IntelAtom_E3900_ApolloLake_I_Android_ReleaseNotes_Rev1_6.pdf' and follow this guide.

I build android Marshmallow  successful and boot on Leaf Hill CRB.

It show warning message : " BOOT_STATE is RED but allow to boot anyway on eng builds! "

I want to handle message and cancel warning.

How can I do?

If I want to build user mode, how can I set it up?

Thanks.
