[beagleboard] Power Button doesn't work on 4.1.10-ti-r24

[Erik Stauber]

Is there anything I need to do to make the power button work on the latest 
Jessie images?  It worked fine on 3.8.X.

Thanks,
Erik

Re: [beagleboard] updated config-pin?

[Erik Stauber]

4.1.10-ti-r24 P9_29 works for me.


However, I get that error for P8_10.

config-pin P8.10 low

bash: /sys/devices/platform/ocp/ocp*P8_10_pinmux/state: No such file or

[Heath Raftery]

A positive update on the HoRNDIS front: the preview version (rel8pre1) has 
been confirmed to work on the latest OS X, 10.11.1. Still no word on FTDI.

Re: [beagleboard] Cannot get audio over HDMI working

[Gerald Coley]

Only two resolutions support audio over HDMi. Unless you use one of those
two resolutions, you will not get audio over HDMI.

[beagleboard] Web application with the BeagleBone Black

[fuenmayor . sirius]

Hello everybody, I want to make an application for a BeagleBone Black 
running linux connected to a magnetic card reader and a touchscreen, the 
BeagleBone Black will be connected to the internet. When a user passes his 
card trough the reader the code in the card is sent to a remote server 
which finds information related to the user in a database (text and 
pictures) and then sends this information back to the BeagleBone Black to 
be shown.  

What are the best programming languages and libraries to develop this 
application in the BeagleBone Black and in the server without using a web 
browser? Do you know of any open source software that do what I ask?

Gerald,

Can you elaborate on what I should be looking at on that page?  As I 
mentioned in the original post, I have already poured through it.  I tried 
both of the resolutions that it claims support audio over HDMI, with no 
success.  I definitely saw the screen resolution change visually, but no 
audio was apparent.

[beagleboard] Running android on Beaglebone black

[arunbarnabasjohn]

Hi,

I have been running Angstrom on the BBB for some time now, however I would 
prefer a OS that does not need a battery backup I have found that just 
switching OFF the BBB (with Angstrom or Debian) causes startup problems due 
to improper shutdowns.

Is it possible to avoid this by using android OS instead, or does this also 
need a battery backup to allow for a proper shutdown process ??

I have seen many Android TV stick devices running via USB or HDMI, but 
these do not have battery backup, but instead rely on a TV for power. How 
are these devices able to prevent shutdown problems ??

The application I am planning to run will not use the SDcard or any other 
backup devices, the application will reside in the SDCard though , but 
hopefully would run entirely from the RAM. This way I hope to prevent any 
problems due to improper shutdown...

Please help me with my queries


thanks
a

[beagleboard] Beaglebone with Teensy with Touch Screen

[intrigueddeveloper]

What would be the steps for me to create numberpad application on the 
beaglebone that I can run on a touch screen and connect the beaglebone to 
my pc and read the input as a HID device, in a way creating a mini keyboard 
on the beaglebone and "emulating" a keyboard for a windows PC ?

My first inclination was attaching a teensy to the beaglebone and send the 
pressed values to the teensy and the teensy processes it and sends it as 
ASCII values to the PC. Would this be the best way to approach this problem 
?

I have no experience with the beagleboard just on an Arduino.

Thanks

[beagleboard] Beagle bone not network/serial accessible over USB in Mac OS X El Capitan

[hraftery]

To save others the angst, I just wanted to report that on the latest Mac OS 
X (El Capitan 10.11) the Beaglebone Black is currently not usable via the 
USB connection, except as a storage device. The alternative is to power it 
somehow and connect via Ethernet.

Normally there are two methods of console connection via USB: as a virtual 
network device using HoRNDIS or as a virtual serial device using FTDI USB 
Serial drivers. Both are thwarted by El Capitan because it enforces kext 
signing, but for slightly different reasons:

   - HoRNDIS simply hasn't been signed for the latest OS, so refuses to 
   load. A preview version that is signed has become available (discussed 
   here: 
http://beagleboard.org/Community/Forums?place=topic%2Fbeagleboard%2Fsp3_x1k5WP8%2Fdiscussion
 
   and over at the source: https://github.com/jwise/HoRNDIS/issues/42 ) but it 
   does not appear to work with the Beaglebone.
   - FTDI's drivers contain a long list of recognised chips, but the 
   Beaglebone isn't one. Adding support is a simple matter of adding the 
   vendor and product ID to the kext, but unfortunately doing so invalidates 
   the signature and the kext will no longer load!

If anyone discovers improvements on this state of affairs then please let 
us know. I'll do the same.

Regards,
Heath

[beagleboard] Setting up cross compiler under OS X 10.11 / El Capitan

[Joe Ciarcia]

I've found some great resources out there that help us Mac folk out with 
building an arm toolchain on the OS X platform. Here they are if any others 
stumble across this thread looking for the same:

http://www.benmont.com/tech/crosscompiler.html
http://will-tm.com/cross-compiling-mac-os-x-mavericks/
http://hansbot.blogspot.com/p/beaglebone-black-mac-os-x-toolchain.html 
 (this one is the most detailed)


I've gotten through a few of the stumbling blocks but I'm currently stuck. 
I get this far:

[INFO ]  Performing some trivial sanity checks

[INFO ]  Build started 20151023.200552

[INFO ]  Building environment variables

[00:03] /


So, after that, if I look at the activity monitor, bash is around 100% 
processor utilization on one of the cores. I figure "great, it's doing 
something". I left it to do its thing and after an hour, I killed the 
process. I changed a few settings... ran it again... same thing. Okay... 
maybe it just takes a really long time. I left it overnight. This morning 
it was still near 100% processor utilization and nothing had changed in the 
build.log file. Here's the last few lines from the build log:


[DEBUG]  =

Any suggestions on how to debug this? Obviously it's attempting to do 
something given the processor utilization but... what the heck is it hung 
up on?


One thing worth noting... early in the process the build log had an error 
with regards to not being able to find the ginstall tool. Since this was at 
the beginning of the test process I figured it hadn't gotten to building 
anything yet and as such, ct-ng clean was not needed (maybe I'm wrong). As 
part of running ct-ng build it creates a directory structure (running clean 
deletes this structure and all the tools included) at 
/YourCaseSensitiveDirectory/.build/tools/bin. My solution was to just cp 
install ginstall, and that got me past that error. Not sure if that's 
contributing to anything but I thought it worth mentioning. Is there 
another way around the missing ginstall problem?


Cheers, Joe

Thanks Robert, as I mentioned, it was impossible to read that as the 
website wasn't up. I figured it was just one of many other dead links I've 
come across. Just bad timing, it was back the next day. I certainly don't 
expect engineers who are volunteering their time to have any obligation to 
update anything at all. It was merely a question as it appeared that 
support for that particular tool had been dropped based on the links 
provided on the getting started page (and in Googling around, the only 
other references I found for FTDI and HORNDIS were a few years old).

Now that it's back up, I can see that it looks like a few people have come 
up with some workarounds in the interim. 

I actually managed to get up and running without any of that by connecting 
to root@beaglebone.local via ssh and then grabbing the IP through ifconfig 
so I could launch the Cloud9 IDE.

Cheers, Joe

[beagleboard] Re: OSX el Capitan breaks HoRNDIS?

[Joe Ciarcia]

If you're just getting started and are new to using the BeagleBone Black 
(as I am) you've no doubt read and watched countless videos that insist you 
must get this ethernet over USB working in order to change the BBB to a 
static IP before you can move forward. I've not found this to be true. You 
can connect directly via ethernet. Just connect one end of an ethernet 
cable into your BBB, and the other directly into your Mac, or connect the 
BBB directly to your router (many of these tutorials say you need a 
crossover cable for a direct connection to your computer... it's 2015, you 
do not need a crossover cable to connect directly to your computer (well, 
unless you're using a relic). 

I suspect you may know some of the following, I'm just going to explain it 
down to the basics just in case there are others who are new to the *NIX 
command line.

The default config of the BBB is for a DHCP connection... this will work 
great (all of these tutorials seem to suggest you need a static IP, you do 
not). The Mac's default config on the Ethernet port will of course also be 
DHCP.

Open a terminal window and type:

ssh root@beaglebone.local

If it asks for a password, just hit return (there is none). You should now 
be connected to the BBB. If you want to find the IP so you can use Cloud9 
just type:

ifconfig

It will respond with something like this:

eth0  Link encap:Ethernet  HWaddr 6c:ec:eb:b0:0e:a0  

  inet addr:192.168.2.2  Bcast:192.168.2.255  Mask:255.255.255.0

Your IP is under eth0, in this case my board has an address of 192.168.2.2


If you want to launch Cloud9, open up a browser and enter 192.168.2.2:3000 
for the URL and hit return. Cloud9 will take a few seconds to start up, and 
then you're good to go. 


If your want your BBB to be able to access the net from your Mac, open up 
your system preferences, click on sharing, and then make sure the internet 
sharing box is checked, and the appropriate ethernet port is selected. You 
can test to see if it's working by pinging Google from the terminal (either 
in Cloud9, or from the terminal window you opened for SSH)


ping www.google.com


Now... if you DO want to configure a static IP, you can do that now by 
typing:


nano /etc/network/interfaces


There are plenty of tutorials that can show you how to modify this file... 
just make sure you know exactly what you want to do as modifications to 
this file may prevent you from connecting via ethernet the next time around.


Cheers, Joe
