Devicetree with IoT Images 4.4.36

Hello,

I setup a new BBB with the image IoT 4.4.36.

But there I miss the /sys/devices/bone_capemgr.9/slots folder.

I need some Uarts and some inputs/outputs at the GPIO

Is in this firmware different?

Thank you!

With the 4.x kernels the path has changed to: /sys/devices/platform/bone_capemgr/slots

Yes, I found this. But, when I do the command :

echo BB-BONE-SWI:00A0 > /sys/bus/platform/devices/bone_capemgr/slots

I get this error :
sh: echo: I/O error

Any suggestions what I’m doing wrong? All the online info seems to have the old syntax.

Thanks,

Jon

/sys/bus/platform/devices/bone_capemgr/slots or

/sys/devices/platform/bone_capemgr/slots seem to be the same dir via a ln, and give the same error.

Yes,

echo BB-BONE-SWI:00A0

needs to change to:

echo BB-BONE-SWI

Well, I still get the
sh: echo: I/O error
message.

Here’s the dts file :
