Device Tree overlay fails to load about pybbio HOT 10 CLOSED

Hmm, that is a bit odd. I believe that capemgr raises an IOError when it can't find an overlay file, so it could be that the overlays didn't get compiled right when you installed. What's the output of # ls /lib/firmware/PyBBIO-*?

from pybbio.

I guess you are right. I only found '.dts' files.

I didn't think there would be a problem regarding this as when I ran setup.py, it got installed with zero warnings!
How do I fix this!
Thanks.

All the corresponding ".dtbo" files are present in /lib/firmware though. Is this where they are supposed to be?

from pybbio.

Wait, they are present or they aren't? They're not there in the screen grab, which would cause the IOError. Do you have gcc installed? # which gcc

from pybbio.

Oops, I mean do you have dtc installed # which dtc

from pybbio.

• Only ".dtb" files are present /lib/firmware/PyBBIO-src
• which dtc prints nothing!

from pybbio.

To install dtc on Ubuntu:

# wget -c https://raw.github.com/RobertCNelson/tools/master/pkgs/dtc.sh 
# chmod +x dtc.sh 
# ./dtc.sh 

Then run the PyBBIO installation again and it should work.

from pybbio.

I did an "apt-get install device-tree-compiler" (dtc.sh was not able to complete execution for network reasons, so I chose apt-get as an alternative). Installation of dtc was successful and "# which dtc" printed "/usr/bin/dtc"

Now I tried installing PyBBIO again, but it gives me this error while setup.py executing :
(I believe the error is caused at line 130-132 in PyBBIO /tools /install-bb-overlays.py)
************ stderr output ***********
dtc: invalid option -- '@'
Usage:
dtc [options]
Options:
-h
This help text...... etc

same thing repeated many times, one for each dts file.

from pybbio.

Yeah, the current dtc build for Ubuntu has a bug. The dtc.sh script is a workaround to build it from source until the apt build is updated. How did it fail?

from pybbio.

It's just a network problem, the beaglebone black does not connect to all the links.
"Err http://ports.ubuntu.com raring-updates/multiverse
could not connect "
Fails at different points of time though
(i.e.) one time it goes through till 12 Get requests (Get:12 http://ports.ubuntu.com raring/universe Translation-en [4,613 kB] )
sometime it fails at 3rd Get request itself!

No big deal, I'll fix it soon. Should work after that! [I'm also considering switching back to angstrom linux]
