Thank you
Your suggestion was helpful for me.
And now I have some problem with insert a device tree to slot file in 
/sys/devices/bone_capemgr.9 by "cat slots" command

 0: 54:PF---
 1: 55:PF---
 2: 56:PF---
 3: 57:PF---
 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI

it was not show after I insert "echo myoverlay > slots" and I recheck by 
 "cat slots" command again it's not show in list
And it's show error like this
"-bash: echo: write error: File exists"

I think it tell me that has file in it already but it's not show!!!!
