Where I live (Szczecin, noth-west Poland) I think this board is
worth about 30-40 hours of specialist work. The idea of compiling on
a system that is simmilar to target sound ok to me, it makes sense
that you dont need to crosscompile- But is that more comfortable for
work? In a crosscompilation enviroment all I need to do is press
debug and it runs. In this case there would have to be some kind of
chain where files fly from my pc, through strong arm board to the
beagle. But i gues you can automate that at some point.

No one was saying change boards. Use the same
board, but use a faster, more powerful ARM board
to compile native ARM executable. The reasons
are simple. No need to mess with cross
compiling, which in many cases is messy, and
sometimes near impossible.

  
  You don't think Robert spends days, or weeks

  Robert. Robert, hey what percentage of the

Re: [beagleboard] Running Qt gui application on BBB


  
  
I understand. Well, I did have some little experience with
crosscompiling std projects and wiritng in eclipse thanks to Derek
Molloys tutorials. All my problems really started when I had to use
Qt for beagle. And yes I cant say Im a pro at this stuff...

The idea with a separate board is good I think, I will definetly
look for a strong and cheap one. i have never thought of doing it
this way though, I always thought people use QEMU and etc.

Thank you for your advices, I really am gratefull for the time.

The boards do not even have to be similar. They just need to be
able to support the same ABI. Which in the case of both the
Beaglebone Black, and the X15( and wanderboard plus countless
others ). They just need to support the armhf ABI. armv7 outside
of the Debian world.

  But
  is that more comfortable for work? In a crosscompilation
  enviroment all I need to do is press debug and it runs. In
  this case there would have to be some kind of chain where
  files fly from my pc, through strong arm board to the
  beagle. But i gues you can automate that at some point.
  
  

Let me put it this way. I'm fairly experienced when it
  comes to working with this sort of thing. With that said, I
  would not cross compile Qt. There are lots of things I would
  not cross compile. For instance, my buddy came to me asking
  advice on how to cross compile Wireshark for the Beaglebone
  black, then he probably wondered why I was looking at him
  crazy . . . My suggestion after finding out he was running out
  of memory was to hook up a USB hard drive, and use it as a
  swap disk. This worked fine for him. He did not mind waiting
  several hours for the binary to compile.
  

Anyway, my point there is that there are many ways to do
  the same thing. All should be taken into consideration. But
  what experience has taught me over the years. Cross compiling
  should be the very last resort. Unless you happen to find a
  very good guide. So considering that you seem to be fairly
  inexperienced. Yes, I think you should consider buying a board
  to help with your development. Especially considering you have
  a grade riding on your projects outcome.

Re: [beagleboard] Running Qt gui application on BBB

Ita the 1st one i see with active cooling. Its not as flexible as beagle
x15 but is it important if you only want to build code on it?

As for the package, i have downloaded qt 5.3.2 but wasnt able to run the
code yey because of some qt version incompabilities. But that something i
can fix soon, i just wasnt able now i had go to sleep. The question is why
did i need this lxqt image specifically if i had to install anyway?

For purely building armhf code, Odroid XU4 might be a good choice:

http://www.hardkernel.com/main/main.php
<http://www.hardkernel.com/main/main.php>

This is an Octacore processor with 4 CortexA15 and 4 CortexA7 processors. I
don’t know how good their kernel/debian support is, but I know Robert had
looked at this board or a predecessor in the past, so perhaps he can give
his input here.

Clearly this board doesn’t have the flexibility of the BeagleBoard-x15 with
it’s dual DSP, Dual CortexM4, Quad PRU, SATA interface, PCIe interface, etc.

By the way, I have no idea what Robert is talking about. You need to ask him.

Now take into account that figuring out how to cross compile something like
this is a serious headache, and often takes days, if not weeks to get right

Re: [beagleboard] Running Qt gui application on BBB


  
  
I cant change the board right now, it has to be BeagleBone Black.
Thats why I need to build on my host. Did you succed on installing
QT5.1 and deploying it to BeagleBone Black? Maybe I should use it
instead of 4.8.6 if its easier?

  If you search for this mailing list for "QT5.1.1 running on BeagleBoneBlack”, I
describe building QT5 on the BBB. 
  

  Here is what I
  said back then:
  

  
QT: git://gitorious.org/qt/qt5.git
Branch: v5.1.1
BBB #>./init-repository
BBB #>make
Takes about 40 hours to build
BBB #>make install
Takes about 2 hours to install


I agree with William, you are better off using a quad
  core board or something similar.

  You could always purchase an ARM multi core build
  system. A few here seemed have have used the
  wanderboard with good success. But now the X15
  hopefully won't be too far off, and is supposed to
  be considerably faster.
  

Anyhow, natively on the BBB, building would probably
take half a day or more if 1h on a decent cross
compile system. Not to mention you would possibly
need to setup a swap disk on external media. For
instance, compiling Wireshark natively took several
hours, and required my buddy here to use an external
USB drive as a swap disk . . .

Re: [beagleboard] Running Qt gui application on BBB

Okay, I think I figured it out, but it would be a bit messy... So lets 
say I would have a postbuild script on my host, that after each 
succesfull build would scp over all .h and .c files to BeagleBone Black 
and build on the target as well (ssh command).


But then again, for gdb-multiarch I need to provide an executable on the 
host. So if I am building on target device, do I need to download the 
built executable back to host...?

Re: [beagleboard] Running Qt gui application on BBB

The point is I dont want to write code on the BeagleBone Black itself. 
Is it, lets say, possible to remote debug in qtcreator on host machine, 
but build on beagle? That is the case. I have always done it like this 
in eclipse:


build on host,
scp to beagle
remote run/ debug

Would this work in this case?

Why are you wasting time cross-compiling? Just build on the bbb... All
the QT 5.3.2 libraries are available for you to install..

Just export your qtcreator project with the ".pro" file, tar it up,

  Hello there,
I have been trying to setup qt enviroment for bbb for a long
time now but it always failed at some point. This time I
have followed exacly every single step in Derek Molloys
tutorial here: http://exploringbeaglebone.com/chapter11/

For now, I am at the point where manually compiled test gui
app is working, but when I compile using Qt Creator i get
messege: undefined symbol: _ZN7QWidget8qwsEventEP8QWSEvent

To fix that, as user stated in the blog I copied whole lib
folder from my qt everywhere folder from host to bbb. But
that not only disallowed me to run the test gui app that was
working before, but also gave me more errors. Now it says I
cannot load library icui18n. It also says "Qt for Embedded
Lnux data directory is not owned by user 0" If i try to run
as root:

This is 

debian@beaglebone:~$
sudo ./tests -qws
  Unable to load library icui18n "Cannot load library icui18n:
(libicui18n.so.52: cannot open shared object file:
No such file or directory)" 
  Qt for Embedded Linux data directory is
  not owned by
user 0
debian@beaglebone:~$ 

  
  

When I run the executable, the app opens for a sec but when
I move my mouse the screen is getting erased and I can see
what is behind it... I dont know if I explain it well
enough... It doesnt work though.

This is a pity and I dont understand why can I compile a
simple qt program with command line and run it but not one
using Qt creator (before i copy the libraries).

I am really desperate right now, I am struggling with this
problem for a long long time. I would really apreciate help.
I am using:
Qt Creator 3.3.2
gnu-eabihf cross compiller
qt-everywhere-opensource-src-4.8.2

My host is:
Linux vm-debian 3.16.0-4-amd64 #1 SMP Debian
3.16.7-ckt11-1+deb8u3 (2015-08-04) x86_64 GNU/Linux

My beagle is:
Linux beaglebone 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:55
UTC 2015 armv7l GNU/Linux

Please help... I will provide all other information that can
help solve this problem.

On BBB you run gdbserver. On your host, you run gdb and then remote connect 
to your gdbserver. Watch Derrek Molloy’s chapter 7 video I gave you, 
starting at about 30 minutes.

Hello there,
I am experiencing the exact same behaviour. I can build code in command 
line and it works but it doesnt when using qt creator. I get undefined 
symbol: _ZN7Qwidget8qwsEventEP8QWSEvent. Did you solve this issue maybe?

[beagleboard] Running Qt gui application on BBB

2015-12-12 Thread bremenpl

Hello there,
I have been trying to setup qt enviroment for bbb for a long time now but 
it always failed at some point. This time I have followed exacly every 
single step in Derek Molloys tutorial here: 
http://exploringbeaglebone.com/chapter11/

For now, I am at the point where manually compiled test gui app is working, 
but when I compile using Qt Creator i get messege: undefined symbol: 
_ZN7QWidget8qwsEventEP8QWSEvent

To fix that, as user stated in the blog I copied whole lib folder from my 
qt everywhere folder from host to bbb. But that not only disallowed me to 
run the test gui app that was working before, but also gave me more errors. 
Now it says I cannot load library icui18n. It also says "Qt for Embedded 
Lnux data directory is not owned by user 0" If i try to run as root:

This is 
debian@beaglebone:~$ sudo ./tests -qws
Unable to load library icui18n "Cannot load library icui18n: 
(libicui18n.so.52: cannot open shared object file: No such file or 
directory)" 
Qt for Embedded Linux data directory is not owned by user 0
debian@beaglebone:~$ 


When I run the executable, the app opens for a sec but when I move my mouse 
the screen is getting erased and I can see what is behind it... I dont know 
if I explain it well enough... It doesnt work though.

This is a pity and I dont understand why can I compile a simple qt program 
with command line and run it but not one using Qt creator (before i copy 
the libraries).

I am really desperate right now, I am struggling with this problem for a 
long long time. I would really apreciate help.
I am using:
Qt Creator 3.3.2
gnu-eabihf cross compiller
qt-everywhere-opensource-src-4.8.2

My host is:
Linux vm-debian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u3 
(2015-08-04) x86_64 GNU/Linux

My beagle is:
Linux beaglebone 3.8.13-bone79 #1 SMP Tue Oct 13 20:44:55 UTC 2015 armv7l 
GNU/Linux

Please help... I will provide all other information that can help solve 
this problem.

[beagleboard] SSH'ing to BeagleBone Black via usb gadget takes ages

2015-10-16 Thread bremenpl

Hello there,
On my BeagleBone Black I am using the console Debian image version:
Linux beaglebone 4.1.9-ti-r20 #1 SMP PREEMPT Fri Oct 2 05:35:56 UTC 2015 
armv7l GNU/Linux

When trying to connect to the board via ssh using the usb ethernet gadget 
it takes ages, and sometimes it doesnt even work- just hangs and I have to 
ctrl+c. When I am lucky and i do get connected, its really buggy. Letters 
are appearing in the console after a while. Connecting through standard 
ethernet connector works flawlesly.
Is there a way to fix this? I would apreciate all help!

[beagleboard] g_ether gadget usb0 not configured at boot

2015-10-12 Thread bremenpl

Hello there,
I am using BeagleBone Black with Debian console version (3.8.13-bone70 #1 
SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux). I have enabled g_ether 
module for usb ethernet gadget. The problem is, the usb0 interface is not 
visible on boot. I have to manually login to BeagleBone Black and use 
ifconfig:

ifconfig usb0 192.168.7.2

Without that, I cannot connect using usb. I see the interface on the 
windows side but its down. In my interfaces file I have:

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
# Note on some boards, usb0 is automaticly setup with an init script
auto usb0
iface usb0 inet static
address 192.168.7.2
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1

I tried to work around this and added ifconfig usb0 192.168.7.2 rclocal 
file but that ahvent helped as well. 

I would really apreciate all help here- Why isnt usb0 configured at boot?

On the windows host:



On windows host i can ping the board by 192.168.7.2 address and I am 
getting response.
The problem is I cannot ping my host from the BeagleBone Black... 

root@beaglebone:/etc/network# ping 192.168.7.1
PING 192.168.7.1 (192.168.7.1) 56(84) bytes of data.

and it hands like that, I am not responed. Everything seems correct, I dont 
know wither this is a network configuration issue. I would areally 
apreciate all help regarding this problem.

[beagleboard] Kernel 4.1.9 overlays not working

kernel version 4.1.9:

I was trying to load BB-UART5 overlay but I failed. I also dont see any 
overlays loaded I thought I would, like eMMC:
root@beaglebone:/sys/devices/platform/bone_capemgr# cat slots

When I tried to load the tree i got:

And I have compiled the tds before and put the dtbo in /lib/firmware/

Has anything changed in the new kernel regarding dts loading and general 
usage?
I would apreciate all help regarding this topic!

Two things to check:

1) The kernel will load any compiled in overlays in preference to
files in /lib/firmware.  I don't think there's a BB_AVRDUDE overlay
compiled into the kernel, but you can test by changing the name of
your *.dtbo file to something guaranteed to be unique (or give it a
custom version number) and try to load that instead.  That will force
the kernel to look for the file in /lib/firmware.

2) You can crawl through the live device tree (/proc/device-tree/*)
and make sure it's what you're expecting.  It's easy to have one typo
or similar that will mess up everything you're trying to do.  :)

Im.not sure I understand. I am setting the pins in the dts file i pasted. 
Wrting 0x37 to them to set them as inputs with pullups. I then compile a 
dtbo, load then load the dtbo. It gets loaded. I check the pins and they 
are not 0x37. Could you explain again what did you mean exacly? I wanted to 
simply init the pin with device tree overlay and then manage it with sysfs.

Well, since you're using gpio-of-helper (designed to allow export of
GPIO pins via the device tree instead of using sysfs), but *NOT*
actually defining any GPIO pins, I'm not sure the gpio-of-helper
driver is applying your pinmux settings.

Try adding the GPIO pins you want to the gpio_helper stanza in
fragment 1 and configure them as inputs.

Re: [beagleboard] Cannot set pins by overlay

I mean you have pinmux settings, but you're not using the

was written for.  There is a difference between the *PINMUX* is setup
for input and the *GPIO PIN* is setup as an input.

Try adding some actual GPIO entries like these:

[beagleboard] Cannot set pins by overlay

2015-09-09 Thread bremenpl

Hello there,
I just got back to my BeagleBone Black and i have no idea why but I just 
cannot change a pin configuration using overlay nor through export. This is 
what I am trying to do:

I want to set P8_29 and P8_31 Pins to inputs with a pullup (0x37). here is 
my overlay:

/dts-v1/;
/plugin/;

/{
   compatible = "ti,beaglebone", "ti,beaglebone-black";
   part-number = "BB-AVRDUDE";
   version = "00A0";

   fragment@0 {
 target = <_pinmux>;

 __overlay__ {
  ebb_example: BB-AVRDUDE {
pinctrl-single,pins = <
0x0E4 0x37  // P8_29, AVR #RST pin, Input Mode7 pullup
0x0D8 0x37  // P8_31, AVR #HWB pin, Input Mode7 pullup
  
   /* INPUT   GPIO(mode7) 0x27 pulldown, 0x37 pullup, 0x?f

  };

__overlay__ {
gpio_helper {

[beagleboard] No keyboard input in Qt Gui app without sudo

2015-07-02 Thread bremenpl

Hello there,
I am struggling with this problem for very long now, but it got really 
serious just now after I noticed that I also cannot use scripts. Here is 
the case:

I have an embedded Qt application crosscompiled that runs on BeagleBone 
Black. It works Ok, but one thing- It doesnt accept keyboard input if i 
wont run in directly on BeagleBone Black preceeding with sudo. This is a 
problem because:

   - I cannot remote debug application and use connected keyboard, as it 
   doesnt work,
   - I cannot use keyboard when the app is in rc.local file to boot at 
   startup (even though sudo is used there).

This is critical for me at the moment and I cannot find solution to the 
problem for very long. I would really apreciate all help regarding this.

My /etc/enviroment content is here:

QWS_MOUSE_PROTO=IntelliMouse:/dev/input/mouse0 
QWS_KEYBOARD=LinuxInput:/dev/input/event1 
TSLIB_CONFFILE=/etc/ts.conf 
TSLIB_PLUGINDIR=/usr/lib/ts


 

Although I have tried many different configurations for QWS_KEYBOARD. The 
keyboard I would like to use is /dev/input/event1.

Here are my persmissions: My application rights are:

-rwxrwxrwx 1 root root 353100 Mar 2 2015 OvenViewer


 

And the input device rights are:

crwxrwxrwt 1 root root 13, 65 Mar 1 21:45 event1


 

I have set the rights in a file /etc/udev/rules.d/85-pure-data.rules:

KERNEL==event1, MODE=777



It really seems that all persmissions have been granted and even though, the 
keyboard doesnt work with Qt app
if i wont run it with sudo directly in the BeagleBone Black command line. I 
Also dont understand why my script in
rc.local doesnt work:

sudo /home/debian/OvenViewer -qws -nomouse 
exit 0 

I have used sudo there. I would really apreciate all help with this, I am 
not able to proceed with my project with this problem existing and I think 
I have searched everywhere for the solution. I also tried with suid bit.
Please help.

[beagleboard] ESP8266 linux driver

2015-06-24 Thread bremenpl

Hello there,
I was looking around but couldnt find any info about the topc- I was wondering 
about using the cheap esp8266 module with BeagleBone black, but I couldnt find 
anything about it in the web. I understand that this is a bit differebtly 
working device than the wifi usb dongles (i gues its more SoC), but havent 
anyone though of using it with bbb? The board uses only uart lines, that would 
be very efficient and cheap. If anyone had any information about it I would 
aprieciate all help!

What do you need to know? The device does look exactly like any old 
modem/terminal. Problem is they are slow. Whilst great for sending modest 
sized messages ('Hello World') they will not cut it for streaming video.


Try hooking one up to a PC with a USB serial adapter - you'll get an idea 
of capabilities pretty quickly.

Re: [beagleboard] DTS for keyboard Keys question

2015-05-20 Thread Bremenpl

I have just tested the dts again. My configruation is a tact switch 
connecting the line to ground. The line is internally pulled up. When i 
used:

gpios = gpio3 9 0x0;
The letters apperead when i released the button, not when i pressed it. 
When i changed to:

gpios = gpio3 9 0x1;
The letters apperad on a button press. It seems like is the way around. 
1 means falling edge and 0 is rising edge. Is this correct?

[beagleboard] 2.2 TFT SPI LCD pwm polarity change

2015-05-20 Thread bremenpl

Hello there,
I am using this dts with an Adafruit 2.2 TFT SPI LCD screen: 
https://pastebin.com/vrUZ0Wde
To drive backlit, pwm is used. My problem is that it is not inverted and 
BeagleBone Black pins cant give/ sink to much current, not enough for 
backlit. So in order to drive not inverted pwm i have to use 2 FETS (N 
driving P) instead of one P one:

https://lh3.googleusercontent.com/-ml820OohPBI/VVyAfOQCmMI/Ahw/DcKyKvfL2BM/s1600/fets.png
 
https://lh3.googleusercontent.com/-ml820OohPBI/VVyAfOQCmMI/Ahw/DcKyKvfL2BM/s1600/fets.png
BL - BeagleBone Black pin for backlit
BL_P - LCD backlit pin

If I could invert the pwm signal in the dts, then i could use BSS84P 
directly, without BSS123.
I Would aprichiate all help in this matter!

[beagleboard] DTS for keyboard Keys question

2015-05-19 Thread bremenpl

Hello there,
I am trying to create a dts file for an 8 buttons keyboard. The pins I am 
using are:
P8_35,
P8_36,
P8_39,
P8_40,
P8_41,
P8_42,
P8_43,
P8_44

HDMI is turned off. Using Dereks molloy book, I have found an example dts 
file for P9_15 key: https://pastebin.com/kKp3ji7s

There are 2 main parts for me:
pinctrl-single,pins = 
0x040 0x37 // P9_15 pull-up mode 7 GPIO1_16

This first one is quite straight forward for me, I have chnaged it to my 
needs:
pinctrl-single,pins = 
0x0d0 0x37 // P8_35 pull-up mode 7
0x0c8 0x37 // P8_36 pull-up mode 7
0x0b8 0x37 // P8_39 pull-up mode 7
0x0bc 0x37 // P8_40 pull-up mode 7
0x0b0 0x37 // P8_41 pull-up mode 7
0x0b4 0x37 // P8_42 pull-up mode 7
0x0a8 0x37 // P8_43 pull-up mode 7
0x0ac 0x37 // P8_44 pull-up mode 7

The problem is I dont know how to config this part:
 button_P9_15 {
debounce_interval = 50;
linux,code = 28;
label = button9_15;
gpios = gpio2 16 0x1;
gpio-key,wakeup;
autorepeat;

I dont know how to interpret gpios = gpio2 16 0x1;. I Think that 16 
0x1 stands for Gpio1[16], but I dont know what does gpio2 stands for. 
Please correct me if I am wrong. What would be the configuration for the 
P8_44 button? I tried gpios = gpio2 9 0x2; but that did not work. The 
overlay loaded but the button doesnt work. It is wired correctly though. I 
Would aprichiate all help.

Well, first is this v3.8.x or anything later?

In 3.8.x: Gpio1[16] = gpio2
while, in 3.14.x: Gpio1[16] = gpio1 ;)

So for 3.8.x: GPIO1[16]

gpios = gpio2 16 0x1;

gpio2 = GPIO1
16 = 16
0x1: GPIO_ACTIVE_HIGH (0x0 = GPIO_ACTIVE_LOW)

[beagleboard] How to compile code on Linux Host with -lprussdrv

2015-04-23 Thread bremenpl

Hello there,
I am following Derek Molloy's book on pru programming and I have run into a 
problem. I have my user space c++ application build on a remote x86 linux 
pc. I am using cross compiler there to deploy executables to the BeagleBone 
Black. So far it was working great but it does not with pru. Is there a way 
to download the pru package to the host machine and be abble to use 
-lprussdrv linker flag? I tried compiling the package on BeagleBone Black 
and then to copy the:

 „libprussdrv.a”
 „libprussdrvd.a”
 „libprussdrvd.so”
 „libprussdrv.so”

to the /usr/lib/ and cross compiller lib/ folders on my host machine. The 
code then compilled with the linker flag but i had seg fault on the 
BeagleBone Black when trying to run the part of code where i open the asm 
.bin file.


The problem is also that I am not able to compile the example code on the 
BeagleBone Black. I have placed the include and lib files in the /usr/lib/ 
and /usr/include/ dirs of BeagleBone Black. This is the example code:
https://pastebin.com/nSsgU7Mk

When trying to compile using (on bb) gcc test.c - test -lprussdrv i get:
https://pastebin.com/nE3dAQ7b

I am wondering either the pru header file has acces to the .c file? Or is 
it handled by the library? Should I place the prussdrv.c file somewhere for 
the header to see it?

I would really aprichiate all help.

[beagleboard] A way to compile PRU user apps on host PC

2015-04-23 Thread bremenpl

Hello there,
I was wondering either it is possible to compile user applications for 
BeagleBone Black, that require lprussdrv linker flag? So far I have copied 
the libs:

libprussdrv.a   
 
1
libprussdrv.so  
   

libprussdrvd.a  
 

libprussdrvd.so

that were created on BeagleBone Black, to the cross gcc lib directory on my 
host pc. Then I am able to compile and link the code with -lprussdrv flag, 
but when trying to execute it I am getting segmentation fault (when running 
remotelly) or this output when running from BeagleBone Black:

AM33XX
File ./test.bin open passed

The program then hangs and I have to kill it.
I would really appreciate all help in this matter!

This is the output of dmesg:

There is no sign of BB-BONE-DVID-01 loading, but only BB-BONE-DVID-02,

I have managed to calibrate the screen, the proper device was event1 as i

2015-03-07 Thread bremenpl

I have just realised one thing- When I connect the monitor to the 
BeagleBone Black using USB, there appears 3 input entries (input0, 1 and 
2). What I forgot to mention is that I had an usb dongle connected to the 
monitor itself, because it also server as a usb hub. In this scenarion then 
a USB dongle (keyboard + mouse) is connected to the USB hub in the monitor 
and then the monitor itself is connected to the BeagleBone Black. I wil 
have to check what input number is the touchscreen exacly when i get the 
hardware again. But even though- I tried to use all of them in 
/etc/enviroment

[beagleboard] Dell monitor touchscreen and QT tslib

2015-03-06 Thread bremenpl

Hello there,
I have a E2014T dell touch monitor and I am trying to use it in pair with 
BeagleBone Black. The touch module is connected using usb cable.
I have read in this tutorial: 
http://embedded.von-kannen.net/2014/05/21/qt-4-8-6-on-beaglebone-black/#comment-4288
How to enable the tslib and touchscreen. But I think, that this reffers to 
a touchscreen not connected to the usb, because it doesnt work.

Without adding those variables to enviroment:
$ sudo nano /etc/environment
- add the following lines
QWS_MOUSE_PROTO=tslib:/dev/input/event0
TSLIB_CALIBFILE=/etc/pointercal
TSLIB_CONFFILE=/etc/ts.conf
TSLIB_PLUGINDIR=/usr/lib/ts
- Save (Ctrl + O) and exit (Ctrl + X)
$ sudo reboot

Touchscreen works out of the box, but it is not even close to being 
calibrated. The offset is really big and it changes when my finger is in 
different part of the display. After enabling the:

QWS_MOUSE_PROTO=tslib:/dev/input/event0

Touchscreen stops working. I feel like its not event0 at all.
When I run ts_calibrate and try to press the crosshair, it doesnt work. It 
feels like touchscreen is off for the ts_calibrate program.

Does anyone has any expirience in such usb touchscreens and BeagleBone 
Black? I Would really aprichiate some help.

hardware on me. I remember that there are inputa from 0 to 3 though. I 
tried all of them I think. The touch screen only barelly works with none of 
them selected and they appear only after i connect the monitor through 
usb... Weird.

Which version of Qt are you using?
Debian or Angstrom On the Bone?
Is there any other event in /dev/input?

Re: [beagleboard] Re: BeagleBone Black as reliable 3G/4G router/ modem

2015-01-16 Thread bremenpl

Right now I am trying to use the tutorial from here:
http://crazy-embedder.blogspot.it/2014/12/beaglebone-black-as-3g-router-or.html?m=1

The difference I have other model of the huawei modem (e3131). After I hit 
lsusb, I dont see the full string like:
Bus 002 Device 005: ID 12d1:1003 Huawei chnologies Co., Ltd. E220 HSDPA 
Modem / E230/E270/E870 HSDPA/HSUPA Modem

All I see is:
Bus 001 Device 003: ID 12d1:14db Huawei Technologies Co., Ltd.

Dont I have a driver? How can I install it? Is it even available? Tried to 
google and found nothing.

After i get to the sakis3g config I choose the Huawei stick:

And after that I cant connect:

Sorry for that, ive done it by accident i think.
So I tried to install the network-manager, but it was not fully 
installed because it run into some errors (I think im not abble to 
install a single package clean there...). After the restart there is 
still no eth1 or any other.


Normally I was also always using interface file to config everything.

Well a quick google lead me to:-

which I suspect will solve your problem (or at least move it
forward).

David

The bit that is important is the bit about using sg_raw.  The USB
stick
defaults to looking like a CD (so that the windows driver can be
loaded)
and you need to tell it that is not what you want, you want the modem.
That is what the instructions do.

 Hello there,
 Ive had it with my internet provider for a while now. I have a free
 BeagleBone Black and a usb huawei 3G modem laying around though. So I
 thought- wny not connect the usb modem to BeagleBone Black to get internet,
 and then connect BeagleBone Black to my router via ethernet to distrubute
 it further. I was trying to accmplish this approach some time a go by
 googling around and trying to set up some programs on a debian distro
 without success...
 I was wondering- isnt there any straight forward solution for aplication
 such as this? Maybe a separate OS even, I dont mind? This is the only task
 I would like BeagleBone Black to do- get and then distribute internet.
 I would really aprichiate any help in here, it would be really great for me
 to set this up.

openwrt maybe?

[beagleboard] Re: DVI cape .dts file for BeagleBone Black

2014-12-08 Thread bremenpl

I have done another approach. I booted the BeagleBone Black from a standard 
debian image on a sd card. I turned off hdmi and emmc and turned on the 
BB-BONE-DVID-01 dts. Then when I booted, I could for a second see something 
on the screen, but it seemd like there is a sycing problem, as it was only 
some blurry like. When In the debug window i have seen:

[   26.468200] tilcdc 4830e000.fb: timeout waiting for framedone

and the screen went black. Does anyone know what could be the case?

[beagleboard] BeagleBone Black based module boards

2014-12-03 Thread bremenpl

Hello there,
I was wondering either are is any board on the market that has the same 
hardware as BeagleBone Black (mcu, mmc, ethernet etc) but is designed as a 
module, with more I/Os and no connectors? Like those popular All winer A20 
module boards. I would aprichiate any help.

Thank you. The board is quite expensive though. Arent you planning 
designing any new board based on BeagleBone Black but made as a module 
:P? Raspberry Pi did that.

All the I/O is used up on the BBB. Nothing more to add. But some of it

[beagleboard] Re: External HDMI circuit configuration problem

2014-12-02 Thread bremenpl

I have obtained some new information. Being on IRC, a kind person suggested 
me to connect 2 monitors at the same time- one to the bbb standard 
connector and one to mines. The tda chip would then configure the EDID and 
my circuit with TFP410 would just start to work being connected to the lcd 
lines- AND IT DID. I have succesfully sent video to a monitor connected to 
my circuit! Thanks to that, I know that the hardware is all ok. All I need 
to do now, is configure the software to make the board get EDID using my 
circuit and i2c2 bus. 

Could anyone suggest any hints here? I tired the elinux.org page with hdmi 
but without luck.

[beagleboard] Loading custom capes on Debian

2014-11-24 Thread bremenpl

Hello there,
I am suing bbb and a Debian Console image. I am strying to locate the place 
where the tree overlays are located but I cant. I tried greping for 
BB-UART1 for example but I cant find it. Even though I can export it to 
slots. I have added my custom cape to /lib/firmware/ but when I try to 
export it to slots it cannot find the file. In the regular image all 
tree-overlays are stotred in /lib/firmware/ and in my image that folder is 
empty. I would really aprichiate any help, this is very urgent for me and I 
dont have much time :(

Re: [beagleboard] Change I2C bus for video communication

Okay, I have managed to load the tree overlay by hand from 
/lib/firmware/. What was wrong was that I havent followed the naming 
style. I have changed the name of .dtbo file to 
BB-BONELT-HDMIN1-00A0.dtbo and I could load the tree overlay by hand. 
Although, the overlay didnt want to load automatically after placing an 
apropriate line in uEnv.txt.

I am not sure if I turned off the standard HDMI overlay, I just 
commented the enables lines in uEnv.txt, now my slots file looks like this:


root@beaglebone:/sys/devices/bone_capemgr.9# cat slots
 0: 54:PF---

 5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
 6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN

I have loaded the HDMIN1 tree overlay by hand, because it failed to load 
at boot. I dont know if thats the case but I got no visual on the 
monitor connected to my external hdmi circuit. I have tried changing and 
the recompiling it for both I2C1 and I2C2 as I was not sure whats the 
proper naming style. The I2C 1 in software is I2C2 on header (that is 
the bus i am connected to using hdmi socket).


i2c = i2c1;

I dont know now either the problem lies in the hardware I have created 
or the wrongly configured software. I would really aprichiate any help 
in this matter. I have copied the circuit for HDMI nearly fully from 
HDMI circuit for Beaglebone Mx so it seems to be correct. I have also 
soldered everything really carefully.


I would really really aprichiate some more help.

You have disabled the HDMI overlays, if they were loaded the relevant

(I believe the L stands for Loaded)

Re: [beagleboard] Change I2C bus for video communication


Some update on the progress:
I figured out that I have switched SDA and SCL lines for the monitor 
connection through HDMI. I have flipped that to proper position and I 
can see additional devices on the bus:

0x20, 0x37, 0x3a, 0x4a, 0x4b and 0x50 appear after I connect the monitor 
ro hdmi connector.


I think I have figured out that I have to put i2c = i2c2; in the 
overlay file, as I think it reffers to the hardware number.


Now when I boot BeagleBone Black in the debug console I see:

There are some errors regarding reading data from TDA chip. When i 
placed i2c1 in the tree overlay file it just said one line about hdmi 
i2c problem.


Looking forward to your answer.

Re: [beagleboard] Change I2C bus for video communication

2014-11-24 Thread bremenpl

I wonder, Maybe there has to be more software changed than only tree 
overlay for i2c? I am using the chip that BeagleboneMx used. It doesnt use 
hotplug and CEC for example...

Re: [beagleboard] Loading custom capes on Debian

I have solved the issue, the problem was the naming. Thank you. Now I 
struggle with the hdmi:

For some reason he doesnt see my .dtbo file in lib/firmware/ but or the

I can echo BB-UART1 for example, I just cant figue out where. I dont know

They are built in..

Re: [beagleboard] Change I2C bus for video communication


Do I have to place this part:

dvicape {
compatible = ti,tilcdc,tfp410;
i2c = i2c2;
pinctrl-names = default;
pinctrl-0 = bone_dvi_cape_dvi_00A1_pins;
powerdn-gpio = gpio2 31 0;
};

In the overlay file you have provided me erlier instead of HDMI part? Or 
do I have to get rid of more? I am not sure which parts exacly can go.

I figured out that I have switched SDA and SCL lines for the monitor

0x20, 0x37, 0x3a, 0x4a, 0x4b and 0x50 appear after I connect the monitor ro

I think I have figured out that I have to put i2c = i2c2; in the overlay
file, as I think it reffers to the hardware number.

Now when I boot BeagleBone Black in the debug console I see:

Does that mean hes not using the driver for tfp410?
Also, could you please confirm either the I2C2 in the tree overlay is 
the I2C2 on the header? I am still not certain.

Re: [beagleboard] Change I2C bus for video communication

I know those sheets. Even thought it says that pinumux is I2C2, in the 
software for i2ctools i reffer to nr 1 not nr 2. Thats why I am confused.
