[beagleboard] Devicetree problem

First does [/sys/devices/bone_capemgr.9/slots] exist?

Second:

Regards,

I am having the exact same issue with my XBee cape. Strangely the ttyO2_armhf.com overlay I found online loads, creates ttyO2, but it seems like my Python scripts don’t actually talk to it at all!

Dear Robert!

Sorry, I doesn´t recognize that you answering my post, as I delete.
I delete because I found my mistake.
It was a case sensitive problem. I wrote the filname camel case and in the Devicetree not.
