[yocto] new system booting directly to halt

You could sell this as a very secure box ;)
Kidding aside, it didn't "zip" through runlevel 5, in fact, you don't know
what runlevel it is actually in. 11 seconds after your file system is
mounted, a reboot is issued. From your trace, nothing running in userspace
displayed any messages to the console. You didn't mention what type of
init system you are using, systemd or sysV. It almost looks like a console
problem. But...i don't know why a reboot would be issued. That's not
normal behavior if you simply have a min-configured console. Maybe init
will do that under certain circumstances, I am not sure.
Just for FYI, notice that your serial port is instantiating on ttyS0. (I do
see that agrees with your kernel command line so at least that much is
correct.)
First thing I would try is to see if I can get anything on userspace. Try
using init= on your kernel command line to just spawn a shell.
(init=/bin/sh)
Do you have a way to examine the flash after a reboot to see if a syslog
was populated on the file system and examine its contents? ie JTAG?
Make sure your root file system is sane, ie mount it on a development box
and make sure it's contents make sense to you. ie for sysV /sbin/init
should point to init, and it should contain a /etc/inittab and that should
have sane contents, etc. For systemd, /sbin/init should point (possibly
through /etc/alternatives) to a systemd executable. You get the idea.
Good luck,
Chris
