[beagleboard] Unable to run MJPG-Streamer on BeagleBone Blue using C270

[Daniyal Ansari]

Im trying to use mjpg-streamer  on 
my Beaglebone Blue running Debian 8.7 

 (bone-debian-8.7-lxqt-4gb-armhf-2017-03-19-4gb.img.xz).

I am also using 2 C270 logitech webcams but am only trying to stream one at 
a time.

This is the tutorial 

 
I have been trying to follow to install MJPG-Streamer as it uses the 
BB-Black which is the closest tutorial I can find to the BB-Blue.

Here are the commands supplied by the tutorial.


sudo apt-get install g++ curl pkg-config libv4l-dev libjpeg-dev 
build-essential libssl-dev vim cmake

sudo apt-get install imagemagick

wget https://github.com/shrkey/mjpg-streamer/raw/master/mjpg-streamer.tar.gz

tar -xvf ./mjpg-streamer.tar.gz

cd mjpg-streamer

make

sudo make install

./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"


This is my result fom running* ./mjpg_streamer -i "./input_uvc.so" -o 
"./output_http.so -w ./www":*

The only modification I made was to the port that the server runs on where 
I changed it from 8080 to 8090.

Thank you!

 Hi all,
 
 I have to bring this thread to life again, as I'm facing the same issue:
 
 all I want to do is to assign p9_29 as "spi_cs" on my BBB running 
 "4.9.78-ti-r94".
 
 Running "config-pin -l p9_28" leads to "default gpio gpio_pu gpio_pd 
 gpio_input spi_cs pwm pruout pruin". So all looks good, as this pin can be 
 used in spi_cs mode.
 
 Now I want to configure the pin to actually work as spi pin:
 
 config-pin p9_28 spi_cs
 P9_28 pinmux file not found!
 sudo: no askpass program specified, try setting SUDO_ASKPASS
 Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P9_28_pinmux/state
 
 The same error is printed when running "config-pin p9_29 spi" or 
 "config-pin p9_31 spi_sclk". However, command "config-pin p9_30 spi" works 
 well.
 
 Would really appreciate if someone can help out here!
 
 Best regards,
 Marco

 All pins are GPIO by default, with pull up/down set to match the reset
 defaults of the processor.  To use P9.28 as SPI, in addition to
 loading cape-universal, it is necessary to run:
 
   config-pin P9.28 spi
 
 If this does not result in the pinmux being set to spi, it's a bug.

Hi all,

thanks for your responses. I will check once back in office and come back 
to you with results. 

@cmbaker3/Chad: would it be possibe to share your uEnv.txt file with me 
(with the dtbo enabled)? Just do be sure that I do the right thing here...

Would be great and thank you so much!!!

Best,
Marco

Re: [beagleboard] Trouble using config-pin to config P9.28 pin as spi or gpio

[Chad Baker]

It is a workaround for a bug, I believe. When I enable the dtbo, I get 
the following directory constructed during the boot process

/sys/devices/platform/ocp/ocp:P9_28_pinmux
Without the dtbo, this directory is missing.

[beagleboard] Re: BeagleBone Black powered by PoE (Power over Ethernet)?

[Thomas Hoppe]

We have launched a BBB PoE cape here, it will be available for sale soon: 
https://www.n-fuse.co/devices/SBCPoE-BBB-Power-over-Ethernet-Cape-for-BeagleBone-Black.html
If you want one, you can contact me.

Re: [beagleboard] Trouble using config-pin to config P9.28 pin as spi or gpio

[Chad Baker]

Did you add the BB-SPIDEV1-00A0.dtbo to the device tree boot list in 
uEnv.txt?

Hi all,

I have to bring this thread to life again, as I'm facing the same issue:

all I want to do is to assign p9_29 as "spi_cs" on my BBB running 
"4.9.78-ti-r94".


Running "config-pin -l p9_28" leads to "default gpio gpio_pu gpio_pd 
gpio_input spi_cs pwm pruout pruin". So all looks good, as this pin 
can be used in spi_cs mode.


Now I want to configure the pin to actually work as spi pin:

config-pin p9_28 spi_cs
P9_28 pinmux file not found!
sudo: no askpass program specified, try setting SUDO_ASKPASS
Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P9_28_pinmux/state

The same error is printed when running "config-pin p9_29 spi" or 
"config-pin p9_31 spi_sclk". However, command "config-pin p9_30 spi" 
works well.


Would really appreciate if someone can help out here!

Best regards,
Marco

All pins are GPIO by default, with pull up/down set to match the
reset
defaults of the processor.  To use P9.28 as SPI, in addition to
loading cape-universal, it is necessary to run:

  config-pin P9.28 spi

If this does not result in the pinmux being set to spi, it's a bug.

[beagleboard] Declaring and using matrices in edumip_balance_ros.cpp

[vandenhove . t . work]

Hy Everyone,

I'm struggling a bit in my school project (Automation Engineering MA1)

Main goal is: implemating a state-space control instead of the PI 
controllers in the BeagleBone Blue Bot
My simulation of the inverse pendulum is done on Simulink and now I'm 
trying to start playing with vectors and matrices in the main .cpp
==> I found on the Github the librairies containing all vector / matrices 
functions as well as the exemple of using them (rc_test_algebra)

I tried several vector or matrix declarations but as I "catkin_make" the 
projet it crashes: here are my attempts (working in edumip_balance_ros.cpp)



  

(I give you a bit more of the code so you can figure out where I'am 
working), main idea here: creating a 2x2 matrix A filled with zeros, error 
is: *expected constructor, destructor, or type conversion before '(' token 
rc_matrix_zeros(A, 2, 2)*

I tried decoupling the code (more lines) or using the rc_matrix_alloc but 
none of them work :-4


Does anyone have an idea how I could implement a simple matrix or vector 
using the prefabricated functions in the librairies please ? I'm merely 
asking for a clue or a good explanation or someone pointing at my bad 
understanding of C++ and correcting me.


Thank you, Thomas from Brussels

[beagleboard] Embedded Apprentice Linux Engineer videos posted on-line

[Jason Kridner]

https://e-ale.org/

"Are you an Embedded Engineer who is transitioning to using Linux? Attend
seminars on how to start with using Linux for Embedded Applications. The
Embedded Apprentice Linux Engineer program provides a place at existing
Embedded conferences where you can get your questions answered.

"Embedded Apprentice Linux Engineer (E-ALE) is a series of 9 seminars over
3 days at existing Embedded Linux conferences. Take as many or few as you
want to. The seminars will each represent a key topic relevant to Engineers
new to Embedded Linux. Each seminar starts with a 45 min lecture or
presentation on one subject, followed by 1 hour of lab time to practice the
relevant learned skills (most often on real embedded HW). Each seminar will
be taught by a professional Embedded Linux Instructor with years of
practical experience."
