Re: raspberry pi Rpi3 does not boot to login prompt.

Hello Quentin,
I made the change that you recommended (see below) and the Rpi3B+ booted without displaying the dmesg 
output only 
Please wait: booting...

My meta-raspberrypi ver ed6b75ba6, I believe was the current version.
How does this modification get updated in meta-raspberrypi?

The ethernet did not get set at boot.  I needed to execute "ifup eth0".
In addition the hostname was not seen by router.
The dmesg outout is at my github.

Let me know if I can provide additional information.
Thanks

I think you might be missing `ENABLE_UART = "1"`. We have it in
local.conf but I think you should be able to put it in your machine conf
file or in your distro conf file if you can't modify local.conf
persistently.
