The point is this. If you require something the standard factory images
need. Don't screw around with someone elses build guide, or images. The
beagleboard.org site has links to all factory, and custom images built by
the same people who build the factory images. Then if you want to get
"crazy, google "eewiki debian on beaglebone black", and Follow Roberts
guide that he uses in part, or whole to build the factory images.

[beagleboard] Can't locate /sys/class/leds folder

2017-10-21 Thread QuarkyUp 
Hey all,

So I followed this paper in order to setup my Beaglebone Black : 
free-electrons.com/doc/training/buildroot/buildroot-labs.pdf

But now that I want to try out some simple code (blinking on-board LED), I 
can't find the "leds" folder where I can manipulate those LEDs.
There is no "leds" folder inside "/sys/class".

I tried to find the folder using the find command, but it doesn't return 
anything relevant to it.

Where can I find this folder ? Or is there anything to do before accessing 
it ?



Thanks by advance !

[beagleboard] Bb Blue and EduMip host issue

2017-10-21 Thread wade beatty 
Hi,

I am working with my grandson on the EduMip robot with BB Blue. 

It is assembled and I can start it balancing through cloud 9 with 
rc_balance but not with balance.py where we could control it with the arrow 
keys.

I get an error on RUN with balance.py:
-
Your code is running at http://localhost.
Important: use os.getenv(PORT, 8080) as the port and os.getenv(IP, 0.0.0.0) 
as the host in your scripts!
---

I would like to know how to change the host and port so that balance.py 
will function. I have googled the sht out of this and spent time looking at 
editing /etc/ssh/sshd_config but this would only change the port.

I am a newbie but enjoying learning here

thanks for the help 

swade
