Without UIM daemon, what instruction do you use to load the BT firmware?

I was thinking 'hciattach' but I was having trouble.  I was hoping you
might have some insight.

 hciattach -t 30 -s 115200 /dev/ttymxc1 texas 3000000 flow  Just
returns a timeout.

I modified my i.MX6 device tree per the binding documentation and
setup the regulators and enable GPIO pins.
