capemgr hasn't been ported fully from 3.8
Use this repo:
https://github.com/RobertCNelson/bb-kernel/tree/am33x-v3.15
<https://github.com/RobertCNelson/bb-kernel/tree/am33x-v3.15>
You can enable extra usarts by adding this to uEnv.txt
cape=ttyO1

I have switched to the image you've recommended and succeeded only
with enabling ttyO1, The other ones are not enabled. I've defined
them like that in uEnv.txt:
/cape=ttyO1
cape=ttyO4
cape=ttyO2
cape=ttyO5/
Is there a way to disable HDMI? cape_disable=capemgr.disable_
partno=BB-BONELT-HDMI,BB-BONELT-HDMIN in uEnv.txt is not working,
but since you said that capemgr had not been ported to new kernel
I'm not surprised. If it's not possible to do in some other way,
which is the latest system where capemgr works?
Ok, I managed to switch off hdmi by removing all hdmi-related entries
from dts files and recompile the kernel. That's not the most elegant
solution for sure, but it works;) The uarts' issue still waits for the
solution.
Well, I think there is a better solution, but since you already
recompiled the kernel, I did just like you and edited
