[beagleboard] Bonescript serial communication ttyO4
I would like to send and receive data from ttyO4 (P9_11, P9_13) using bone script. Unfortunately I didn't find any projects or examples, how to make it with bonescript. It should be just a normal serial connection with 9600 baudrate. Does anybody have some tips, how I can access ttyO4 with bonescript?

[beagleboard] Cross Compile from Ubuntu on PC
I got the TI sdk for beagle bone black here. http://www.ti.com/tool/linuxezsdk-sitara I selected Linux EZSDK for Beaglebone Black. I successfully set up eclipse and it all works fine if I static link. However if I don't it doesn't work. My assumption then is that my helloworld program will not dynamically link with Angstrom on beagle bone black. Do you think that is true they are not compatible? Perhaps it would work if Ubuntu was running on Beaglebone Black?

[beagleboard] Weird Qt cross compiling issue
Hi
I recently bought a Beaglebone Black, with the LCD4 cape as I want to start
learning about ARM development and embedded linux.
The board has worked for be flawlessly and I easily now have the board with
Qt4-embedded running on the built in Angstrom distro. The videos by Derek
Molloy were very helpfull, though they seem a bit out of date now.
Anyway over the last several weeks of weekends and some weekday nights,
what has been causing me pain is trying to setup an anstrom sdk and
cross-compiling toolchain, but I'm almost there, I just have a weird Qt
linking issue.
As a background, I'm doing this all on a Debian Virtual machine because the
Angstrom 2012.12 setup doesn't work in my normal Fedora 19 (relies of some
deprecated functionality that was removed in one program in F19).
To setup my tool chain I did these commands:
mkdir angstrom_beaglebone
cd angstrom_beaglebone
git clone git://github.com/Angstrom-distribution/setup-scripts.git
cd setup-scripts
MACHINE=beaglebone ./oebb.sh config beaglebone MACHINE=beaglebone ./oebb.sh
update MACHINE=beaglebone ./oebb.sh bitbake virtual/kernel
MACHINE=beaglebone ./oebb.sh bitbake systemd-image
MACHINE=beaglebone ./oebb.sh bitbake meta-toolchain
Then I found out about meta-toolchain-qte, so I then ran:
MACHINE=beaglebone ./oebb.sh bitbake meta-toolchain-qte
Then I installed the SDK:
cd
~/angstrom_beaglebone/setup-scripts/build/tmp-angstrom_v2012_12-eglibc/deploy/sdk
sudo ./angstrom-eglibc-i686-armv7a-vfp-neon-toolchain-qte-v2012.12.sh
Installed into default place, but had some permissions issues so in
/usr/local
ran:
sudo chmod -R 777 oecore.i686
finally I've added this into my .bashrc:
source
/usr/local/oecore-i686/environment-setup-armv7a-vfp-neon-angstrom-linux-gnueabi
Now for the test project, which is based on Derek's video though slightly
tweaked.
I've installed the Qt5.1.1 SDK and am using the QtCreator 2.8.1 from that,
though using the 4.8.1 that comes with the sdk.
Here's my .pro file:
#-
#
# Project created by QtCreator 2013-10-05T14:41:31
#
#-
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = qttest
TEMPLATE = app
target.files = qttest
target.path = /home/root
INSTALLS += target
SOURCES += main.cpp\
mainwindow.cpp
HEADERS += mainwindow.h
FORMS+= mainwindow.ui
QMAKE_CXXFLAGS += -Wno-psabi
I've set the kit to use the adk's GCC and the sdk's qmake2 file.
Now, release build works great. I have it setup for deploying onto the BBB
and that works fine. The release build qmake's, compiles, links, deploys
and runs great on the BBB.
I'm having trouble with debug mode, qmake2 runs fine, and it compiles, but
I get this issue when I think it tries to link:

[beagleboard] Signal Processing on the BBB
Hi guys, I'm totally new to MCUs and the Beagleboard and I'm a little overwhelmed by the amount of information out there. For a class project, I need to sample a signal (the beat signal out of a FMCW radar module, the frequency is not higher that audio), detect its frequency, and use this frequency value to calculate the range and/ or speed of my target. I'm pretty sure that I can use either the beagleboard-xm or the beaglebone black for this, but I'm confused about a couple things. I hope that I can get help here! Can I just use the CPU on the BB-xM or the BBB to sample the audio and do the necessary processing or would I have to use the xM's DSP or an audio cape for the BBB? I have written simple DSP applications in C before, and so far I have used JACK to get my samples from the sound card. Could I do the same thing on the Beagleboard? Would grabbing samples for computations in a C program also work by using ALSA? In order to detect the frequency of my signal, I believe that I will have to take chunks of the signal, take the FFT and detect the peak in the resulting array. Can I do these operations on a beagleboard without significant delay? Thanks for your help!

[beagleboard] Re: How to open ports on compiled ubuntu-13.04-console-armhf-2013-07-22.tar.xz
The behavior you describe is what I have sometimes got when it doesn't have the right root partition mounted. If you boot up with a micro sd card installed, it may be trying to mount that filesystem as root. Does it behave itself when the external SD card is removed? I have had three problems so far: 1. System gets into a mode where it will boot, machine is pingable, USB is working (because ctrl-alt-del works on a USB keyboard) but none of the services are running (can't ssh to the unit) and the HDMI video isn't working (have a signal but not displaying anything). Once the unit gets into this mode, the only recovery is to re-flash it. It has done this twice. 2. Sometimes when power is applied it will not boot. The LEDs don't light, nothing. Cycling power to the unit via plug/unplug of the power supply clears the problem' 3. Commenting the entries out of /etc/network/interfaces for usb0 has no effect. I have commented out the lines in /etc/network/interfaces but it still comes up active. My guess is that your system is trying to mount the sd card as the root partition and none of your service daemons are there. Which image are you running? I think for me the problem of booting with an sd card was fixed with the image found on BBB-eMMC-flasher-ubuntu-13.04-2013-09-27 but even running that image it ended up hanging once in that mode where it won't boot from either eMMC or sd, interface comes up, is pingable, but no services start, no display from HDMI, keyboard works. That sounds to me like the problem you are facing. The only way out of that mode I have found so far is re-flashing the unit. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Found a potential solution for EDIMAX wifi issues on BBB with Angstrom
So, here is my success story :) I tried a few days to get an EDIMAX 7811UN to work on my BBB with Angstrom. The built-in rtl8192cu did not work, compiling realtek driver from source was not helpful as well. An upgrade to image-2013.09.04 changed nothing. The signal level was very weak and connection was lost, as soon BBB was 3 meters far from my AP. Finally I got it out with disabling of HDMI. My thoughts were: why is there so much over HDMI in dmesg? HDMI port is near USB ... So, what... I've mount the FAT partiotion and change the uEnv.txt to: optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN Now, EDIMAX works without usb extension cable, seems to be stable and I can put my board in an other room :) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BBB is a great home server but printing is a challenge
I had a windows desktop PC running an X10 based home control program and being used as file backup for my laptops. It was power hungry and noisy because of the fans. I boldly decided to replace it with a $45 BBB running Linux and consuming around 5 watts. I installed a console version of Angstrom which leaves me lots of space on the built-in 2 Gb flash. The home control software is heyuhttps://www.google.com/url?sa=trct=jq=esrc=ssource=webcd=2cad=rjaved=0CDgQFjABurl=http%3A%2F%2Fheyu.epluribusunix.net%2Fei=sIRRUqfYMYSE9QTb94GICgusg=AFQjCNEaKmhgou2L8fDbxubbCUHfyWIWmAsig2=Ry8Y_RawA1-dAVvoND3p_Qbvm=bv.53537100,d.eWUand heyu web interface. I like them better than the Windows software that I had on the PC. They are more reliable and easier to interface to with C or sh programs. I bought a $5 USB audio adapter to generate the barks of a mean dog when motion is detected. It works perfect. I use samba to do my backups onto USB flash drives plugged into the BBB. Works more reliably than the PC. I am so happy with Linux and the BBB that I wanted to do one more thing with it, printing. I have an older HPlaserJet printer that is no longer supported by Windows but works well with CUPS and HPLIP on a Linux PC. I installed CUPS from Angstrom but had to download the source version of HPLIP. I managed to make it and install it but not to get it to work. I gave up but maybe someone smarter and more knowledgeable has already done it.

Re: [beagleboard] Re: BBB does not appear as USB drive
Hi, I just bought my BBB for the first time too, I followed the instructions on the beagleboard.org site and downloaded the drivers first, then installed them, after installing, I plugged the BBB in the USB and it detects it but it doesn't recognize it as a USB device which is very confusing considered that I didn't flash the eMMC or anything of the sort. I keep removing the drivers and reinstall them but still the same result. I can't see it as a USB device but the Windows detects it in the port but can't configure the drivers for it (other words the yellow exclamation mark on the BeagleboardBlack in Device Manager). Is there an updated version of the drivers maybe or is there a step that i missed in the instructions because I followed from the beginning. Any help would be very appreciated. Thanks.

[beagleboard] Fast boot, no-GUI distro?

I'm embedding this in a robot, don't really want those things, and the faster it boots, the better. It'd be nice if there was someone making a distro like this on a regular basis, keeping it up to date. It would be a lot faster to install.

[beagleboard] Beaglebone drivers would not load on windows8 machine
Hi All, I had trouble getting my windows8 pc to upload beaglebone drivers. The problem is all new window8 pcs are automatically set to not allow installation of unsigned drivers. Here is the fix 1. Press win+c on the keyboard to bring up the charms side bar (or move mouse to right top corner of the screen) 2. Click the Settings button. 3. Click the Change PC Settings at the bottom of the sidebar. 4. On screen that shows up, select the General option from the sidebar then scroll down the page that appears. 5. Click the Restart now button under the Advanced startup section. 6. You will momentarily see the restarting screen, then it will switch to a blue screen titled Choose an option 7. Click the Troubleshoot button. 8. Click Advanced options. 9. Click Startup Settings 10. Click Restart 11. You should then see a Startup Settings screen after your computer reboots. 12. Press 7 or F7 on your keyboard to Disable driver signature enforcement 13. Now Windows 8 will continue starting up. 14. Log-in as normal, and then run BONE_D64.exe again 15. Now you should see 4 warning dialogs about unsigned driver installation, click OK for all of them. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BBB 24-bit LCD using device tree
I have created a custom cape for a 24-bit LCD and am having trouble getting
the upper bits (16) to work. I have disabled the HDMI and on board eMMC.
The panel comes up but is not showing all 24-bit color.
Where can I find full descriptions of the data entered into a Devcie Tree.
I have searched for a technical reference document an cannot find one (does
it need to be BBB specific?)
Here is what I am using:
panel-info {
ac-bias = 255;
ac-bias-intrpt= 0;
dma-burst-sz = 16;
bpp = 24;
fdd = 0x80;
tft-alt-mode = 0;
stn-565-mode = 0;
mono-8bit-mode= 0;
sync-edge = 0;
sync-ctrl = 1;
raster-order = 0;
fifo-th = 0;
invert-pxl-clk;
should be 24-bit output. What does fdd mean? I'm assuming bpp is in
decimal and somehow getting written to the correct register.

Re: [beagleboard] Signal Processing on the BBB
This is something I have been reading about rather than having done it myself, so I may be wrong about details, but here's what I understand. The Doppler radar setup will give you a beat frequency between your tranmitter and receiver. IIRC, Doppler frequency is 1/(1+2v/c), so for instance when an object moving at 1m/s is lit up by 5GHz, the receiver will return a 33Hz beat frequency signal. This is within audio range, so you can read it with a sound cape or USB dongle, or directly via BBB digital or analog I/O pins, if you're careful about not burning them up with excess voltage. You can get the speed by measuring the frequency, but you can't get actual distance unless you do time-of-flight measurement on well-defined pulses, which is tricky because radar waves move at the speed of 1 foot/nanosecond. On a Beaglebone it's pretty hard to measure timing to a resolution much better than a microsecond or so, so your distance measurement would be to within 1000 feet. On Sat, Oct 5, 2013 at 5:41 PM, Dennis Ogbe dade...@gmail.com wrote: Hi guys, I'm totally new to MCUs and the Beagleboard and I'm a little overwhelmed by the amount of information out there. For a class project, I need to sample a signal (the beat signal out of a FMCW radar module, the frequency is not higher that audio), detect its frequency, and use this frequency value to calculate the range and/ or speed of my target. I'm pretty sure that I can use either the beagleboard-xm or the beaglebone black for this, but I'm confused about a couple things. I hope that I can get help here! Can I just use the CPU on the BB-xM or the BBB to sample the audio and do the necessary processing or would I have to use the xM's DSP or an audio cape for the BBB? I have written simple DSP applications in C before, and so far I have used JACK to get my samples from the sound card. Could I do the same thing on the Beagleboard? Would grabbing samples for computations in a C program also work by using ALSA? In order to detect the frequency of my signal, I believe that I will have to take chunks of the signal, take the FFT and detect the peak in the resulting array. Can I do these operations on a beagleboard without significant delay? Thanks for your help!

Then I followed the steps to flash the eMMC. I held the boot button until all the LED's start flashing and only then I release it. After 2 minutes all the LED's turn off including the Power LED. I am using a 5V 2 Amp power supply. Then if I remove the SD card and connect to the board using SSH I can see the default Angstrom flavor. If I insert the SD card and reboot I can see the Debian flavor, I am confused. How can I flash the eMMC with Debian ? Some wiki page mentions the flashing takes 4-5 minutes and some say 45 minutes which is correct ? Am I missing something ?

[beagleboard] Re: How to open ports on compiled ubuntu-13.04-console-armhf-2013-07-22.tar.xz
Thanks George, I actually do want to boot the operating system on the SD card which has two partitions made according to instructions at http://eewiki.net/display/linuxonarm/BeagleBone+Black. The operating system I installed on the SD card is ubuntu-13.04-console-armhf-2013-07-22.tar.xz. The LEDs are operating as I expect from booting my other image (which also boots the SD card) but was a downloaded image as opposed to a compiled image. When I apply power, the LEDs light up after a few seconds as expected. When I hold the reset switch down, then after about 8-10 seconds, the LEDs turn off, again as expected when an SD running machine is turned off. Everything looks right except for the closed ports. On Saturday, October 5, 2013 7:17:19 PM UTC-4, George B wrote: The behavior you describe is what I have sometimes got when it doesn't have the right root partition mounted. If you boot up with a micro sd card installed, it may be trying to mount that filesystem as root. Does it behave itself when the external SD card is removed? I have had three problems so far: 1. System gets into a mode where it will boot, machine is pingable, USB is working (because ctrl-alt-del works on a USB keyboard) but none of the services are running (can't ssh to the unit) and the HDMI video isn't working (have a signal but not displaying anything). Once the unit gets into this mode, the only recovery is to re-flash it. It has done this twice. 2. Sometimes when power is applied it will not boot. The LEDs don't light, nothing. Cycling power to the unit via plug/unplug of the power supply clears the problem' 3. Commenting the entries out of /etc/network/interfaces for usb0 has no effect. I have commented out the lines in /etc/network/interfaces but it still comes up active. My guess is that your system is trying to mount the sd card as the root partition and none of your service daemons are there. Which image are you running? I think for me the problem of booting with an sd card was fixed with the image found on BBB-eMMC-flasher-ubuntu-13.04-2013-09-27 but even running that image it ended up hanging once in that mode where it won't boot from either eMMC or sd, interface comes up, is pingable, but no services start, no display from HDMI, keyboard works. That sounds to me like the problem you are facing. The only way out of that mode I have found so far is re-flashing the unit. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Did you use a crosscompiler? You can also compile your code on your beaglebone. 2013/10/5 ignacio.mata...@gmail.com hi, Looks like there is something wrong in eclipse.

But maybe i am wrong Eclipse with an installed crosscompiler is only one way to go and it certainly makes sense if you have a huge Project with thousands of lines of code, X, etc. But I usually code only small terminal programs (in ANSI C) that read in some ports, write to some ports, do some calculations and write the results to a excel readable text file. For such problems I am too lazy to install Eclipse with all the gnuaebi etc. stuff So, I edit and compile my programs directly on BB, usually over ssh and sftp (usually from my Mac, with Cyberduck). The only thing you need on BB is gcc and if you have a bit bigger projects make. Starting with Hello World is always a good idea Connect to your BB with ssh nano helloworld.c type in your code, quit and save with ctrl x gcc -Wall helloworld.c -o helloworld And run your program with ./helloworld you need the ./ for running terminal programs in the same folder Have fun! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Beaglebone black HDMI/VGA converter problems
I just bought a BBB along with a HDMI to VGA converter from Adafruit (long with the other accroutrements). The converter is very similar to the one pictured on the web page as compatible:.http://circuitco.com/support/index.php?title=BeagleBone_Black_Accessories. Note the one pictured is unpowered, or at least appears to be so, so I figured I would be fine. As you can guess, I have no video (sigh) Is there no way to get this to work with the unpowered adapter? The adapter cost almost as much as the BBB and I can't return it. Oh well...

Re: [beagleboard] Debian on BBB
Okay, the scripts
/opt/boot-scripts/am335x_evm.sh
and
/bin/bash /boot/uboot/tools/scripts/beaglebone-black-copy-microSD-to-eMMC.sh
are both being triggered correctly.
The problem is that beaglebone-black-copy-microSD-to-eMMC.sh is failing to
find initramfs-tools inside check_host_pkgs (), even though the same script
does *not *fail when run later by hand.
That to me sounds like something in the shell environment is affecting the
formatting of dpkg's output.
Anyway I changed check_dpkg () to
dpkg -l $pkg /dev/null || deb_pkgs=${deb_pkgs}${pkg}
and everything appears to run normally.

One thing I forgot(?) to mention: To use the audio cape with the BBB you need to modify the kernel and the devicetree and recompile it. If you want, I will send you the needed patches based on Robert Nelsons BBB kernel (3.8.12), which are only tested for my setup but are not specific for it (I think). I am running Gentoo and NOT Angstrom! I think (but let us wait for the answer on Adafruits support forum) that the output level of the mic+amp is powerful enough to drive the audio input of the Audio cape.

This will release a great processing burden from the shoulders of the CPU. The A/D-converter (analog to digital converter) of the audio cape will do this for you. In the simpliest case, you only need to grab the samples and put it on SD-card/disc (raw format). This means recording. In case of an hearing aid, this is not that useful, since you will hear it later, hahahaha! :) Take a deep look into the datasheet of the tlv320aic3106, which is TIs audio processor they put on the audio cape. This little beast is capable of much more than simple sampling. For example you will get a maximum sampling rate of 96 kHz, which means -- capable microphones provided -- you can sample sound up to 24 kHz. One thing: I dont know, how
