Hi,

I am trying to use USB TTL on raspberry pi 3. I get the console messages
when the device is up, but I get garbage after the message "Starting
kernel ...".

I found the post
http://raspberrypi.stackexchange.com/questions/45007/garbage-on-raspberry-pi-console
and added
dtoverlay=pi3-disable-bt
dtoverlay=pi3-miniuart-bt
enable_uart=1

in /boot/vc/config.txt but it still does not work.

What is the way to to get the serial communication working?

I also noticed the kernel is pretty old (4.1.19-1-rpi2). Is there a
newer kernel we should use? Also, do we have the corresponding dtb trees
for pi3?
