DRA726: Boot timing issue

Part Number: DRA726

How do I get rid of the "start job" parts? It looks like it is trying to connect a network on the USB device which is unacceptable since we only support USB-2 flash devices

Those increase the time it takes to  boot.

Also what needs to be done to remove some unwanted  error messages like those :

My yocto is based on Automotive SDK 6 but using poky instead of arago

I use the arago recipes that I need. The reason for using poky is that we intend to move to Automotive Grade Linux at some point in time and poky is what is used.
