[yocto] Device Tree Overlays

[Raul Rosetto Munoz]

Hello All,

I just compile a Yocto linux for BeagleBone Black using dora branch.

I would like to use device tree overlay to change the pin mux.

But I think that this linux not enable this feature.

I couldnt see this folders:

root at beaglebone:/lib/firmware# export
SLOTS=/sys/devices/bone_capemgr.9/slots

1

root at beaglebone:~/temp# cat $SLOTS
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

Plz some one can tell me what I need to do to use this feature?

Is some thing possible using yocto?

Thanks.
