That was not my script, that was your service edited, with all the

Re: [beagleboard] Re: Beagle expertise needed

2017-01-21 Thread Richard Maurer 
Hey, language.  There are kids on the internet.  BTW, your .service file
had the same bug with a small 'i' in Install, so it would not have worked
anyway.  But as you said in your later post, you're not getting paid, so
I'm not here to quibble.

Anyway, I enabled the service, but it won't start due to some internal
error:

root@beaglebone:/tinkerforge/Example_project# systemctl start
imusend.service
Job for imusend.service failed because the control process exited with
error code.
See "systemctl status imusend.service" and "journalctl -xe" for details.

The shell file runs fine when I call it from the terminal:
/usr/bin/imuout.sh

But the system won't run it as a service for some reason.

/usr/local/lib/python2.7/dist-packages/tinkerforge/ip_connection.py", line
687 simply reads:


while self.receive_flag:
try:
data = self.socket.recv(8192)
except socket.error:
if self.receive_flag:
e = sys.exc_info()[1]
if e.errno == errno.EINTR:
continue


self.handle_disconnect_by_peer(IPConnection.DISCONNECT_REASON_ERROR,
socket_id, False)
break

687 if len(data) == 0:
if self.receive_flag:

self.handle_disconnect_by_peer(IPConnection.DISCONNECT_REASON_SHUTDOWN,
socket_id, False)
break

pending_data += data

This may be a bug in Python 2.7: http://bugs.python.org/issue14623

Per one recommendation:

The most simple workaround is to add timeout

time.sleep(1)

in the end of script that allows the threads to finish before the script
comes to end of life and close


Haven't figured out where to put a time.sleep(1) line.

Re: [beagleboard] Re: Beagle expertise needed

2017-01-21 Thread William Hermans 
Additionally. "Everything" online hasn't worked out for you yet, Has it ?
I've tested what I've done. It works with:

root@beaglebone:~# uname -r
4.4.38-bone-rt-r14
root@beaglebone:~# cat /etc/dogtag
BeagleBoard.org Debian Image 2016-06-19
root@beaglebone:~# systemctl status log-halt.service
● log-halt.service - Halt logger
   Loaded: loaded (/lib/systemd/system/log-halt.service; enabled; vendor
preset: enabled)
   Active: inactive (dead)
root@beaglebone:~# systemctl status log-reboot.service
● log-reboot.service - Reboot logger
   Loaded: loaded (/lib/systemd/system/log-reboot.service; enabled; vendor
preset: enabled)
   Active: inactive (dead)

Which "logging" system going down is actually a small part of the services.
So again, I know what I said will work for you, because it works for me. It
has to work, otherwise I don't get paid. The only thing I don't know for
your case, is what target you need to hook off of. It could be
network.target, network-online.target, or any other number of network
related target I'm unaware of. It could even be more than one target
simultaneously.

So in the future, do me a favor. I took time out of my life to try and help
you fix your problem. Do me the service of at least doing exactly as I
mentioned, before you try to discredit what I'm saying works. Maybe, that
was intentional, maybe not. I honestly don't care. Because I do not get
paid trying to help you with your problem.

Also, there may even be many ways, or slightly similar ways to do the same
thing. Maybe creating a symbolic file link will work ? But if I'm
instructing someone to do something the way I know how, and they're off in
left field somewhere, complaining that what I'm trying to instruct doesn't
work . . . well at some point, I'm just going to stop caring if they find a
solution or not.

2 things:

install the "bb-wl18xx-firmware" package via apt, and make sure you
have the latest kernel:

cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh

or just grab my latest 16.04 image:

It's a different stack, and we don't really have TI's new userspace working yet.

So keep in mind when I say it bugs the s**t out of me when someone says
they followed my instructions when they fail to duplicate my results.

William Hermans ,
I can assure you that I started with a simple unit file nearly exactly as
you had offered. Knowing little about Linux, I somewhat blindly added
guesses on additional commands, but with no improvement.  And just to be
sure, I followed your instructions to the tee.  I used,
ln /lib/systemd/imuout.service imuout.service
to create the link.  But I had the same result/error message when I attempt
to enable the service.

[beagleboard] BeagleBone Black Image Checksums?

2017-01-21 Thread Desert 
Hi BBB Forum,

I am trying to verify several older BBB images I downloaded from
beagleboard.org, but need help with the checksums.  Can someone
give me valid md5 or sha256 checksums for the following files
downloaded from debian.beagleboard.org/images?

  bone-debian-7.5-2014-05-14-2gb.img.xz
  bone-debian-7.4-2014-04-23-2gb.img.xz
  BBB-eMMC-flasher-debian-7.4-2014-04-23-2gb.img.xz

For the first file, an md5 checksum is listed on the latest-images 
html page.  But it doesn't seem to match the file actually posted.  
I can't find any checksums for the other two files.  

Any help would be appreciated.

Thanks, Desert

[beagleboard] BBBW sgx driver and library

2017-01-21 Thread Pier 
Hi, I have just get  a BBBW for a project,   
I would like to use SDL / OpenGL/EGL  with a frame buffer  (no X),  

What kernel version I should use ?  and where I can get the sdk/libraries ?

I have try with the latest 4.4.43 bone , and I get the:

omaplfb.ko
pvrsrvkm.ko

but without the user space stuffs,  where I can get the user space 
libraries and user space pvrsrv service ? 

 With the latest  4.4.x ti-channel kernel I get only the:
pvrsrvkm.ko
and the user space pvrsrv service seems working:
PVR_K: UM DDK-(3699939) and KM DDK-(3699939) match. [ OK ]

but where I can find the libraries for this version ? its ok that with this 
version there is no omaplfb.ko ?

I have tried to install the 4.1.x kernel but seems  the BBBW didn't boot 
with this version.

thanks,
Pier

[beagleboard] first steps with BBG

2017-01-21 Thread Fabian 
Hello @ all,

I am trying my first steps with the PRUss on the BBG, but nothing I read 
here, will work.
Step by step:
1. I downloaded this image: 
bone-debian-8.6-lxqt-4gb-armhf-2016-11-06-4gb.img
and installed it on sd-card
2. run update, upgrade and dist-upgrade. So my kernel is
 4.4.30-ti-r64
3. cd /opt/source/dtb-4.4-ti && git-pull

Before, During and After this steps I tried to run the loader blink 
example: 
http://www.righto.com/2016/08/pru-tips-understanding-beaglebones.html
For this I compiled the loader, the blinker and the devicetree.
But the loader always reports
prussdrv_open() failed

capemanager tells me, that univ-emmc is loaded. I recompiled it, without 
acces to pru0,pru1,pruss,P8.11 and P8.16.
I then compiled the devicetree of above example and after reboot I didn't 
had any problems loading it.
Also I deactivated the universal cape in /boot/uEnv.txt to be sure 
univ-emmc doesn't make any problems.

I also compiled the PRU-blinker-program of TIs Hands-on-Lab. Placed them on 
the board, linked them with /lib/firmware/am335x-pru0-fw
and run modprobe pru_rproc / rmmod pru_rproc
In lsmod, I can see, if I run modprobe the driver is loaded and after rmmod 
the driver isn't loaded.
dmesg doesn't tell me anything.



What am I doing wrong? Can somebody help? Would be a great thing, else I 
will give up on this device. It took me too long, until I found this forum

You need something like this:

[Unit]
Description=imu output
After=network.target

[Service]
ExecStart=/usr/bin/imuout.sh
Type=oneshot

[install]
WantedBy=network.target

All the rest of that "garbage" is exactly that - Garbage. Your script can
deal with working directory, and not outputting to terminal if that's what
you wish. Then you simply . . .

systemctl daemon-reload
systemctl enable  --now

Making sure that service-name.service exists in /lib/systemd/system/

As far as what target you need, well that I don't know. I have no clue what
an IMU *is* in the context of Nodered, and no idea what you're trying to
do. However, if you need your service to run, and all it requires is a
network to be established. The above should work.

 That's why I introduced the ESP solution.

 It's plug-and-play when you spend a few further bugs and buy a
 developers board like nodeMCU .
 You plug in the USB, start a terminal and you'll also see what's going on
 with it in the Lua interpreter.

 For my engineers mind, this solution will provide faster results. You
 can focus on the necessary features and use a lot of-the-shelf features.

 Anyway, it's your decision. Good luck for your project.

Re: [beagleboard] Re: Syntax highlighter for pasm in Sublime Text 3

2017-01-21 Thread William Hermans 
You can write your own syntax highlighter for Sublime Text3. I say this,
because I've never seen any assembly language highlighting for Sublime text
period. And yes, I do use Sublime text myself( for the last 4-5 years ).
You might try using C highlighting, to see if the standard C highlighting
also highlights inline assembly. But that's doubtful.

I was looking a while back for something similar, and the only thing I
found was someone on parallax's forum's talking about having writen a
syntax highlighter for Visual Studio Code( not to be confused with the
Visual studio IDE ) and the p2asm language. Maybe It's possible to adapt
that, or in a pinch just use it in code. I've been using VSC myself
recently a lot for javascript, C, and C++. It's not a bad text editor at
all.

If you're trying to enable, thus "install" a service with systemctl You
need a Wantedby target.

But just google: "how to systemd" +  and
you'll probably be greated by way more hits than you'll ever need.

[beagleboard] Re: Can a PRU tell if it's PRU0 or PRU1?

2017-01-21 Thread Greg 
I thought of another way.  Kind of crude, but it might work.  This would 
allow the firmwares to be identical.

Assuming you have a spare PRU GPI in each, you could set the pull-up on one 
pin, and a pull-down on the other.
Then you just read the appropriate value of the bit in __R31.  Of course 
you would have to carefully select the pins so they are the same bit in 
__R31.
So if those pins are spoken for in your application, this isn't going to 
work.

Hopefully someone will know a method which is baked-in to the system.

[beagleboard] Ubuntu supporting BBBW's onboard Wifi

2017-01-21 Thread Mike Reynolds 
Hi all,
I have an Ubuntu 14.06 image which runs on the BBBW.  Unsurprisingly it 
does not setup the BBBW's onboard Wifi/Bluetooth.  Is there an Ubuntu image 
supporting the BBBW's onboard WiFi?  Alternately are there instructions on 
installation of the necessary software/drivers?
Cheers,
Mike.

[beagleboard] Re: Can a PRU tell if it's PRU0 or PRU1?

2017-01-21 Thread Greg 
So you are saying the firmware loaded to both PRUs has to be exactly the 
same?
You can't use a slightly different #define to make a different constant in 
PRU0 vs PRU1?

Regards,
Greg

[beagleboard] Can a PRU tell if it's PRU0 or PRU1?

2017-01-21 Thread Ken Shirriff 

Is it possible for a PRU to know if it is PRU0 or PRU1? I want to run the 
same code on both PRUs but have it do slightly different things [*]. I 
guess I could write a "0" to PRU0's RAM and a "1" to PRU1's RAM and the PRU 
code could test this. But is there a more direct way, such as reading a 
config register? I looked over the Technical Reference Manual but couldn't 
find anything.

[*] Specifically, I want the PRU code to send an event to the ARM, 
with PRU_EVTOUT0 from PRU0 and PRU_EVTOUT1 from PRU1, so the ARM code knows 
which PRU sent the event. But I can't see how to do that without the PRU 
knowing if it is PRU0 or PRU1.

Thanks,
Ken
