Thanks for the super quick response Robert, but here is what I have in
uEnv.txt and what dmesg shows:

Hello all,
I haven't been keeping up with all the ins and outs of the 4.1.0-boneXX
kernel. I've downloaded the testing image 4.1.0-bone9 and am curious as to
how to get UART4 running?
Thanks for any direction on this subject,
open:
/boot/uEnv.txt
find:
#cape_enable=bone_capemgr.enable_partno=
Change to:
cape_enable=bone_capemgr.enable_partno=BB-UART4
reboot..
Regards,
