I also get this message here, but it works for me. (It seems that some 
driver programmers learned to output error messages at m$.)

ADC always works, no matter which overlay you used to switch the PRUSS on. 
The question is: can you execute examples with run-time pinmuxing, like 
button or stepper?

Hello there,

methods for loading the device tree at startup.

I tried creating uEnv.txt in /boot/ directory that contains:

# enable dvi
cape_enable=capemgr.enable_partno=BB-BONE-DVID-01

This havent worked so i tried editing /etc/default/capemgr with:

|
CAPE=BB-BONE-DVID-01

But that also did not help, the dts is not loading at startup.
I would aprichiate any hints on this case. Is there any step I
could possibly miss when loading device trees at startup?
I am using debian wheezy.




Hi,
Can you |try the following in uEnv.txt|
optargs|=capemgr.enable_partno=BB-BONE-DVID-01

Hi ,

I want to Learn ARM Cortex Assembly Instruction set and its power, How can 
i do that

I feel that it would be lot better if was able to write modules(how to 
write modules in assembly ?) and insert them and observe the logs through 
dmesg, is that possible ???

i dont want to install any simulator on my PC , neither i want to install 
an IDE which would flash the program again and again to board

so is there any effective way to learn assembly programming using beagle 
bone black ???

Re: [beagleboard] How to transfer data from beaglebone / weather cape.

Hello Shao Min,

I am doing a project that contains a database of images and the beaglebone 
has to access the database for updates. How would you approach this issue 
on calling the database by wireless. I hope you were able to get your 
Weather Cape working.

[beagleboard] revision identification

[akanarya]

Hi,
I am a newbie.
I'll buy a BBB from a diffrenet forum.
How can I identify from the board pics that it is rev C or else?
I couldnt find any print on the board pics that describes the rev number.
Rapid response is appreciated.

[beagleboard] Issues with autostarting services in Debian

[Joe Spanier]

I am using my beaglebone black to run Octoprint for my printer. Its a new 
RevC with the MachineKit Image from elinux.org and I followed the basic 
raspbian install instructions for getting OctoPrint installed which worked 
fine. I also installed X11vnc and mjpg-streamer. All of these work fine 
with started manually over ssh. The issue cosmes when I try to get any of 
these services to autostart on boot. 

for Octoprint  followed these instructions:
Automatic start up

Copy the script files to their respective folders and make the init script 
executable:

sudo cp scripts/octoprint.init /etc/init.d/octoprint
sudo chmod +x /etc/init.d/octoprint
sudo cp scripts/octoprint.default /etc/default/octoprint

Then add the script to autostart using sudo update-rc.d octoprint defaults.

I also tried running this:

# create run-octoprint

cat > ~/run-octoprint 

Re: [beagleboard] libpruio with recent Debian on BBB?

[Brandon Stafford]

Just an update; yes, the .dtbo file was misnamed.

After renaming the file:

cp /lib/firmware/libpruio-0A00.dtbo /lib/firmware/libpruio-00A0.dtbo

I was able to execute:

sudo echo libpruio >  /sys/devices/bone_capemgr.9/slots

That produced this in dmesg:

[  796.178041] bone-capemgr bone_capemgr.9: part_number 'libpruio', version

Make sure there is nothing plugged into the expansion headers. If you can't

I have found a solution to this, so i will post it here for any one 
interested, and for my own future reference. 


I am doing this on Beaglebone Black Debian 
My application does not have a GUI yet so i will be running it from 
terminal, so here is what i have done. 

edit /etc/xdg/lxsession/LXDE/autostart

# comment out lxpannel and pcmanfm, and add the following 

#@lxpanel --profile LXDE
#@pcmanfm --desktop --profile LXDE
@xset s off
@xset -dpms
@xset s noblank
@lxterminal -t NameOfTerminal -e Path/To/Executable/myapplication

the above lunches lxterminal with parameters at startup running the 
application, replace @lxterminal with application of your choice, another 
example is 
@chromium --kiosk --incognito http://www.google.ie

this will lunch chromium in kiosk mode, be sure to have wifi enable to make 
use of it. 

at this stage the terminal has all its menu buttons, which does not look 
well, so i edited the following 

/home/debian/.config/openbox/lxde-rc.xmlin  


no
true


this removes the decor and maximize the window, 

to remove the menu buttons edit .config/lxterminal/lxterminal.conf 

that should give us a nice kiosk type application.

[beagleboard] Multiple 1-Wire Pins

[rob]

Hello,

I use my BeagleBord Black to monitor my heating-system.
I use DS18S20 as temperature sensors.

In the moment there are 7 sensors connected but I need more of them. The 
1-wire bus supports only 10.

How can I have an other pin as a 1-wire-bus-master ?

BTW: I describe my system on my webpage: http://www.powershell.pub/ds18b20/
It is in German language...

Thank you
Robert

[beagleboard] [BBB:GUI app<- packages <- PRU <- SPI ] ======== [SPI <-wifi radio module]

[diac . bernard]

Hello,

I am new with beaglebone black. So far I have been able to enable PRU and 
SPI to operate them from within the OS.
I would like to receive some packages with a wifi module and send them via 
SPI to the PRU unit that can write them into the BBB's OS so that the GUI 
app can have access to them.
I need for the PRU to be able to use SPI full (to not compete with OS for 
that device).

So far I have been reading documentations and I have come up with this:
 -> To use SPI just for PRU I need StarterWare
 -> Do I need a Jtag to use CCSv6 with StarterWare so that I can program 
the PRU and SPI?
 -> I would like to use SPI0 from BBB because the pins for SPI1 are blocked 
by HDMI.
 -> I need HDMI so that I can read and see the captured packages 

Who can help me out with this? Documentations, examples, which are more 
helpfull

Re: [beagleboard] DTO and GPIO output error

[Karl Anderson]

got it downgraded, bone_capemgr.* directories available and uio_pruss 
module available. Unfortunately, ran the blinkled program with the updated 
BBB glibc and still no output to the pins. The cross compilation specs are 
as follows: glibc 2.15 for the linux machine, and glibe 2.19 for the BBB, 
so they should be compatible. Any further thoughts on why this is not 
putting out to the pins?

I flashed the Jessie snapshot to my beaglebone, and got the updated (2.19) 
glibc files, but I can't find the bone_capemgr.* directory to enable a 
device tree? Does that come with the Jessie snapshot? Let me know, thanks!
