[beagleboard] Re: Embedded QT with QT-Creator,undefined symbols
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
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.

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).

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. W dniu 2015-12-15 o 01:14, William Hermans pisze: 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- 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.

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?

[beagleboard] usb serial gadget
Hello there, The bbb image normally comes with usb gadget that simulates ethernet and mass storage. I have 2 questions regarding that: Can the usb additionally simulate serial port? So on the host side one would see a com port (if windows) and on the beagle side it would be a tty interface? If yes, how to enable it? Second question, can serial interfaces in linux be bridged together easily? For example, by connecting the beagle to the pc and writing to the usb serial gadget from the pc, i would like uart5 to send that data. In short terms, can beagle be configured to be a serial uab converter?

Re: [beagleboard] Running Qt gui application on BBB
Hi there, I was not able to solve this. Because of lack of time, I decided to install qt 5+ on the bbb usong apt manager and build serialport (i needed ot and it was not included) on the bbb itself. For now i am stuck with building on bbb without crosscompiling as i wasnt able to set it for qt 5+ as well. If you would find a solution to this i would be gratefull if you let me know. I still need the qt on bbb in own frame buffer version. On January 25, 2016 12:44:23 AM em.ce.kwad...@gmail.com wrote: Have you finally solved this problem?

Dnia 29 września 2014 19:18:09 William Hermans napisał(a): Actually, starting from the LXDE image and then removing stuff you do not want works fine. *IF*, and this is a big if, you know exactly what packages to remove for each thing you do not want. However, there is always aptitude which is a smart where managing packages are concerned. Although I do tend to agree, it is best to start with a minimal image. and work your way up into what you want. There is less chance for something to go wrong this way. Yet we may not know various things such as if this person has project files on an existing filesystem already( or not ).

Re: [beagleboard] How to install the usb0 network adapter
Robert, I just noticed that in the console image when i mount up the mmcblk0p1 that means I am mounting whole filesystem of the beaglebone on the usb. Could you explain me how can I create a custom flash space formatted in ie. fat32 and make it avaible on usb? This is new to me, because in the regular image there was the fat partition of about 100MB under mmcblk0p1.

On the screen I only see the linux penguin image and nothing happends. Only the usr0 led blinks in a loop like schema. I would really aprichiate any help in here, why do those images break?

What is the deal here? Well by default the 200Mb "Console" is just a single ext4 partition... So if you were to add that to the current image, it would get stuck on bootup and spew lots of errors over serial about a missing partition.

Re: [beagleboard] Re: Disable X in new Rev C Debian Image
Hello William, Thank you for the advice. You are right about me when you say that my main os is Windows, but not for 100%. I work on vmware and Linux osses for a longer time now. This is my 1st real aproach on embedded linux though, normally I wrote bare metal code for mcus. Im always eager to learn, but it happens for a time that you have no time and theres like one blocking point for you, but it grows over time. It still remains a blocking point for the project though :p. Also, theres the fact that I find my way around a lot better in hardware than software (especially high level). I will get there eventually, I really aprichite the help given by community. I am really waiting for the book from Mr Derek Molloy to come out, to bad its release date is getting moved. I didnt know about the book from Mr Polstra that seems very helpfull as well and as I said maybe my university could buy one paper version for my use and if not, ill get it mysalfe :). Dnia 30 września 2014 22:51:49 William Hermans napisał(a): Brem, it sounds like me you need to slow down. It also sounds as though for the several posts you've made that Windows is your primary desktop OS. So, this is what I might suggest for you. Start with Virtualbox( virtual machine software ), and install Debian on it. Only a cmdline version (no X-Windows ), and start experimenting. Read posts on the groups here that you have interest on, and google for information about each given process / feature. Over time you'll find out that 90-95% of your questions / answers have nothing to do with the beaglebone hardware, but is more( all ) about Linux instead. Mostly, the more experience you have with Linux, the better off you will be. I know this from experience because prior to owning a beaglebone black I had zero experience with embedded Linux, but several years of hand on with Debian i386 on desktop, workstation, and server x86 based systems. So, just slow down instead of trying to absorb everything all at once, and you shold be able to focus, and learn.

Re: [beagleboard] Custom images stop working eventually
Hello Robert, I think what you said its right... When I enter the mounted directory, it does reflect the files I see on the mounted USB partition. However, When I create a new file in there, it does not appear on the USB drive nor the location in console... I Cant really tell whats happening. After dfing I can see the location mounter correctly: root@beaglebone:/boot/uboot# df Filesystem 1K-blocks Used Available Use% Mounted on rootfs 3553816 251864 3118096 8% / udev 10240 0 10240 0% /dev tmpfs 101692 440 101252 1% /run /dev/disk/by-uuid/7505a30a-815a-441f-96ee-e62f7d07e547 3553816 251864 3118096 8% / tmpfs 254224 0254224 0% /dev/shm tmpfs 254224 0254224 0% /sys/fs/cgroup tmpfs 102400 0102400 0% /run/user tmpfs 5120 0 5120 0% /run/lock */dev/mmcblk0p1 98094 63236 34858 65% /boot/uboot* If as you said this isnt really mounted, is there a way to create a separate partition for the virtual usb space?

[beagleboard] Power Button Script

I have found this script for handling it: #!/bin/sh BTN=/dev/input/event0 while true; do BTNVAL=`hexdump -e '8/2 "%x " "\n"' -n 16 $BTN | grep ' 74 ' | awk '{print $7$ if [ "$BTNVAL" = "1" ] then echo "Power button pressed" /sbin/sync /sbin/sync /sbin/shutdown -h now exit fi sleep 1 done I have put a link to it into init.d and used update-rc to make it work at startup. The problem is that it doesnt always work. Im not sure either it is running in the background or not, because when i use ps command i dont see the script running and even though the power button works. So lets say every 3rd power up the power button doesnt work... Im not sure whats the case. I would also aprichiate if someone told me either this is the proper way of handling the power button in the official bigger image. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] External HDMI output
Hello there, I am currently working on a motherboard for the BeagleBone Black. One of the requiments is to have a HDMI output on the side of the motherboard. I Know that there are LCD pins on the BeagleBone Black header and there is a possibility to connect a LCD cape. I was wondering either it would work to duplicate the NXP HDMI framer circuit that is on the board to the motherboard and use it for hdmi output? If I am correct the only difference would be that there is no acces to I2C0 from headers so I would have to use I2C1/2 for the NXP chip.

There are resistors on the lines, worse case scenarion I can take them off. But tgose lines are used for lcd cape already so it does work, whats the problem?

Re: [beagleboard] External HDMI output
Cant I just power the NXP from 1.8V? If the lines are 1.8V I would need no translation then. Also there are no buffer on the bbb itself so why would I need such? Dnia 8 października 2014 20:12:06 Gerald Coley napisał(a): It is the low voltage level as these are 1.8V inputs. The issue is making sure you get low enough, fast enough due to capacitance and at the correct frequency to yield a good data integrity. You can try using a translator buffer from 3.3V to 1.8V. That should help. Gerald On Wed, Oct 8, 2014 at 12:55 PM, Bremenpl wrote: > I could do buffers as well, thats not a problem. I am building the > board from scratch.

Re: [beagleboard] External HDMI output
I am only asking, no hard feelings :p. Ive just noticed that there were no buffers on the lcd lines between nxp and mcu on the bbb. Thats why I asked. Why are there no buffers on the bbb? By buffers do you mean that a voltage follower would do if the inputs are 3.3V tollerant? Dnia 8 października 2014 20:44:37 Gerald Coley napisał(a): It already is powered from 1.8V. The processor however, is powered from 3.3V. The NXP part is 3.3V tolerant. You need the buffer to clean up the signals and provide better drive as is being done on the LCD boards..

I understand. Thank you. Dnia 8 października 2014 21:03:58 Gerald Coley napisał(a): If you do it right, you should have nothing to do.

Hello there again Gerald, I was trying to get a piece of TDA19988 chip but he is not avaible in a single distributor :|. I was trying to find some simmilar chips from other distributors but I am not sure either they would be compatible. Would you mind helping me out in this case?

Re: [beagleboard] How to avoid shutdown with BBB directly connected to a battery-backup when removing 5V power supply
Hello there Michael, I have just tested my BeagleBone Black. I have connected the power through USB + battery. Then I disconnected the USB and left the BeagleBone Black on the battery. It havent shutdown after a minute or anything. I am using the console Debian image.

[beagleboard] Labolatory power supply fails to power up BeagleBone Black
Hello there, I have a very strange problem with powering up BeagleBone Black (rev C) When i try to power it up from some cheap AC adapter it works fine, but when I connect to to my labolatory power supply the power LED on board is lid for a second and then doesnt power up the MCU and turns off intead. I have connected both supplys to osciloscope and they are both stable, the laboratory one even more. Why is the power controller on the BeagleBone Black refusing to power up the MCU when powered from lab supply? I have no idea what is this about. I would aprichiate any help. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Re: [beagleboard] Labolatory power supply fails to power up BeagleBone Black
I understand, thank you for the info. I will make more attempts at monday with another bbb board. For now I have a 10k resistor on the TS pin because I intend to use the battery to. If the voltage is measured on the resistor ill swap it to lower value one. I hope ill get it working using meanwell power supply. Dnia 14 listopada 2014 16:16:30 Gerald Coley napisał(a): Not likely. As I said we need more boards that fail and the power supply that is used with them. What I have seen is that it tries to switch to the battery, that is not there, for whatever reason. Theory is it sees a voltage drop due to the inrush limit on certain power supplies. I have fixed this on a few boards by connecting the TS signal hard to ground using the battery pins on the board. What I see when the board "does not power up" is the PMIC cycling on and off. You can look at the 5V output rail of the PMIC for this condition.

Ill get it tested, thank you. If this worked it would solve my problem. Dnia 14 listopada 2014 16:41:30 Gerald Coley napisał(a): The output voltage level is different. When the DC is contented it is supposed to go to the DC input and go into charge mode for the battery. Measure the output voltage of the PMIC. If it is 5V, then it is DC in.

Re: [beagleboard] Labolatory power supply fails to power up BeagleBone Black
A question regarding battery though- if i leave the bbb under battery supply, but turn off the mcu with pwr button, what will be the current drawn by TPS chip? Wont it dry the battery through the night? Lets say its a single li-ion cell 2200mAh Dnia 14 listopada 2014 16:41:30 Gerald Coley napisał(a): The output voltage level is different.

Re: [beagleboard] Labolatory power supply fails to power up BeagleBone Black
I have tested the board again and heres what I have come to: - Using meanwell 5V ac adapter works when the 10k resistor is NOT soldered to battery header. If theres resistor soldered, but there is no battery attached it stops working and the power led blinks all the time. It really seems that the power controller is trying to switch to the battery that is not there. After placing the battery everything works correct. I only home it wont get discharged to fast when the board is off. W dniu 2014-11-14 o 16:58, Gerald Coley pisze: And mine.
