Re: [beagleboard] BBB, PRUSSV2, using timer on IEP
Thx. I already found example you mention (glad to know it's yours) and used it as guideline how to use compare registers on IEP. Did reworked the example and now it's running fine. I suspect that issue in my initial example was with following piece of code L1: LBBOrT2, rIEPBase, IEP_COUNT, 4 QBLTL1, rT1, rT2 My expectation was that quick branch instructions does comparison of complete registers (all 32 bits), but in fact it compares only 8 bits (you can chose if it's B0,B1,B3 or B4). In my case I think it was working only rT1.b0 and rT2.b0. For sure that contributed to unexpected execution flow, maybe there was also something else. Although reworked example works just fine, will debug this one as I don't want to leave open ends :) Also will try debugger you mentioned, as writing apps blindly and debug them only with LED attached to GPIO is bit of pain :) Thx Ivan On Wednesday, October 2, 2013 12:16:58 AM UTC+2, Charles Steinkuehler wrote: I don't immediately see anything obvious that is wrong with your code.

[beagleboard] How can I control Servo motor by angle information?
Hello, BB group~ I'm figuring out how to control Servo motor by angle information with my BB. I made a tracking sound c++ code and this code get some angle(degree) information. And finally i got it with my BB. The next step is controlling Servo motor by this angle information. So I'm thinking of 2 methods. First one is using Arduino(send angle information to Arduino from BB), and Second one is BB directly controls a Servo motor. But I don't know how to use gpio in BB and I wonder 2 methods I thought are possible to implement coding by just using c++ in Angstrom linux. Please give me any comments. It will be great help for me. Thanks. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] BBB, PRUSSV2, using timer on IEP
Hm, I have to correct my self. After throwing a second look into instruction format for quick arithmetic test and branch, where register is Op2, QBNE supports comparisons of all bits in both registers (didn't read tables Rs2Sel and Rs1Sel to the end). My mistake... Yet, this than makes my first code not working even a bigger misery. Will have to take a much deeper look at the code.

Re: [beagleboard] How can I control Servo motor by angle information?
You can use a PWM output to drive your servo. Set the PWM cycle frequency to 50hz and the duty cycle to 1.5 ms (~7% = center position). Varying the duty cycle +/- 0.5ms should drive your servo to left and right. Power the servo by an external power source not the GPIOs of the board.

[beagleboard] Remote debugging thru SSH
Problem: 1. You release a wildly successful Beagleboneblack (BBK) product. The product is one where the customer connects the BBK to the Internet thru the router on their home LAN (ie. the BBK is behind a router and does NOT have a public ip address) 2. After product release you find a major bug in your software, and the customer support calls start piling up because of this bug. 3. You find a fix but because most of your customers are not technical, it is difficult for them to update the software. Your customers start ranting about how terrible your brainchild is, you start losing hair, gaining weight, and wish you had gone into accounting instead of engineering. 4. SSH'ing into each BBK would be great because then the fix could be easily applied. I'm thinking of writing a software package that provides a solution to this. In a nutshell: 1. A web server (SERVER1) is built and connected to the internet. BBK Side: 2. Each product is given a unique ID (UNIQUE_ID) before being shipped. 3. A daemon process installed on the BBK sends an HTTP request for a file named UNIQUE_ID on SERVER1. The request is repeated periodically (say once every few seconds). 4. If the request is successful then the BBK sets up an SSH connection to SERVER1. Tech Support Side: 5. Tech support has a list of the customers and their unique IDs. 6. When a customer calls in , Tech support creates and SSH connection to SERVER1. THen creates the file UNIQUE_ID on the server. 7. Tech support can now SSH into the customer's BBK. I am a little unclear still on SSH port forwarding but I am pretty sure the SSH connections thru SERVER1 should be relatively easy to set up. Thoughts, comments, opinions? Is there something out there already that is simple to use? Anybody want to work with me on this?

Re: [beagleboard] Remote debugging thru SSH
The subject line is about debugging, but you talk about updates on the main message. You are assuming that: 1) Every BB that needs to be updated is connected to the internet. 2) If they are connected to the Internet, the SSH port is wide open… 3) They are not turned off in the middle of an update… ;-) ;-) Why not auto update your app? When booting the BB the init script compares the release number of you app (somewhere in a file or in a filename) with the current release number. The current release number is available from an update web server (with the software). If the release number on the web site is greater than the installed, the script downloads the app, checks the integrity of the archive, and if the archive is ok, upgrades the software. This: 1) Works with only the http port open. Does not need any other ports opened. 2) Works also on a network no connected to the Intranet, as long as you place on that network a suitable web server. Warning: I don't think this update method is the subject of any valid patent, but... ;-) ;-) ;-) Best regards Paulo Ferreira -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Bootchart on Ubuntu (slow boot)
Does anybody know how to get bootchart working under Ubuntu? I'm running 12.04 precise off an SD card. I have the bootchart deb installed, but nothing shows up in /var/log/bootchart after reboot. It sounds like I may need to add something to my u-boot commandline, but I'm not sure what or how. Some docs for bootchart refer to /sbin/bootchartd, but I think that's outdated and there's no such thing installed. The Ubuntu package has some stuff for updating the initrd that looks like it might be supposed to take care of things automatically, but it doesn't. The reason I ask is that it takes about two *minutes* for a login prompt to show up over my ftdi serial line. The console logging from the kernel stops after about ten seconds, then nothing for a long time, then finally the prompt comes up.

Have been wrestling with wifi on BBB. I was following this thread and the webpage at http://octopusprotos.com/?p=37 for a static address. I did go to amazon.com and buy the TP-LINK TL-WN722N. Did a fresh load of the BBB from a mid-september image then did 'opkg update ... ' as seen elsewhere. That got me recognizing the device. I installed wireless-tools. Then I replaced connman with /etc/network/interfaces and /etc/wpa_supplicant as in that octopusprotos.com posting. I had a terrible time. Device would attach then drop with reason=3. Then I discovered that I had two wpa_supplicants running! I commented out the pre-up line from the /etc/network/interfaces as found on octopusprotos and now things seem to be working swell. So my addition to the knowledge pile is not to run two wpa_supplicant processes. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Set the PWM cycle frequency to 50hz and the duty cycle to 1.5 ms (~7% = center position). Varying the duty cycle +/- 0.5ms should drive your servo to left and right. Power the servo by an external power source not the GPIOs of the board.

Re: [beagleboard] Remote debugging thru SSH
Thanks for your input. Your auto update method would definitely work. The advantages of SSH are: 1. More flexibility - ability to review syslog files, system configuration, etc. This is where the debugging thru SSH part of my title applies. We have all been thru instances where the customer says My app isn't working.. Being able to SSH into the BB allows one to deal with this type of issue. 2. Ability to upgrade, configure, or modify the system.Yes in theory the app could do this but this makes the app very complex. You write You are assuming that: 2) If they are connected to the Internet, the SSH port is wide open… I'm not 100% sure but I do not think the ssh port has to be open on the customers' router because the TCP connection originates behind the router. On Wed, Oct 2, 2013 at 9:03 AM, Paulo Ferreira p...@keeh.net wrote: The subject line is about debugging, but you talk about updates on the main message. You are assuming that: 1) Every BB that needs to be updated is connected to the internet. 2) If they are connected to the Internet, the SSH port is wide open… 3) They are not turned off in the middle of an update… ;-) ;-) Why not auto update your app? When booting the BB the init script compares the release number of you app (somewhere in a file or in a filename) with the current release number. The current release number is available from an update web server (with the software). If the release number on the web site is greater than the installed, the script downloads the app, checks the integrity of the archive, and if the archive is ok, upgrades the software. This: 1) Works with only the http port open. Does not need any other ports opened. 2) Works also on a network no connected to the Intranet, as long as you place on that network a suitable web server.

Set the PWM cycle frequency to 50hz and the duty cycle to 1.5 ms (~7% = center position). Varying the duty cycle +/- 0.5ms should drive your servo to left and right. Power the servo by an external power source not the GPIOs of the board.

RE: [beagleboard] Remote debugging thru SSH
Sounds like a good idea to me. Not sure how viable it would be due to the number of customers. It might have to be a paid service ?

You release a wildly successful Beagleboneblack (BBK) product. The product is one where the customer connects the BBK to the Internet thru the router on their home LAN (ie. the BBK is behind a router and does NOT have a public ip address) 2. After product release you find a major bug in your software, and the customer support calls start piling up because of this bug. 3. You find a fix but because most of your customers are not technical, it is difficult for them to update the software. Your customers start ranting about how terrible your brainchild is, you start losing hair, gaining weight, and wish you had gone into accounting instead of engineering. 4. SSH'ing into each BBK would be great because then the fix could be easily applied. I'm thinking of writing a software package that provides a solution to this. In a nutshell: 1. A web server (SERVER1) is built and connected to the internet. BBK Side: 2. Each product is given a unique ID (UNIQUE_ID) before being shipped. 3. A daemon process installed on the BBK sends an HTTP request for a file named UNIQUE_ID on SERVER1. The request is repeated periodically (say once every few seconds). 4. If the request is successful then the BBK sets up an SSH connection to SERVER1. Tech Support Side: 5. Tech support has a list of the customers and their unique IDs. 6. When a customer calls in , Tech support creates and SSH connection to SERVER1. THen creates the file UNIQUE_ID on the server. 7. Tech support can now SSH into the customer's BBK. I am a little unclear still on SSH port forwarding but I am pretty sure the SSH connections thru SERVER1 should be relatively easy to set up. Thoughts, comments, opinions?

Re: [beagleboard] Remote debugging thru SSH
Just my 2 cents. Your idea is absolutely feasible. If you take a look at minipwner, it creates an ssh tunnel, which I believe is what you want to accomplish. The only and most unpredictable problem is going to be the end user. If they are like me nothing goes on my network unless I am absolutely sure what it is doing and that I am the one in control of it. So the auto update idea may be your best option. As for the debugging you may also set it up so that it records the logs and sends them out at set intervals. That way the customers are sure that there isn't anyone inside their network when they shouldn't be. On Oct 2, 2013 6:05 AM, monzie monzie9...@gmail.com wrote: Problem: 1.

[beagleboard] Re: Getting Touch Events to work using BeagleBoard xM ULCD7 Angstrom and JavaFX
Hi All, I know that this thread is old but I didn't find an answer yet. I have a similar issue. I'm using a Raspberry PI and a Lilliput 619AT 7 resistive touchscreen. The touchdriver is eGalax. It's working well on X11 but when I run my JAVAFX application, my software can't get the touch events. Running my app over SSH, and doing cat /dev/input/event4 I can see that the touch events are being triggered, because it shows on the terminal some stuff every time I touch the screen on my JAVAFX app. So, I think the problem is that my JAVA app can't identify or read this events. Do you guys have any ideia on how to solve it? Thank you, Sergio Soares On Monday, December 10, 2012 12:05:03 AM UTC-3, carl...@gmail.com wrote: All, I'm trying to create a project to run *JavaFX* applications that will respond to touch events similar to a demo presented at JavaOne 2012 described herehttp://fxexperience.com/2012/10/building-the-javaone-kiosks-park-1/. Instead of obtaining the same 10 display (Chalkboard Electronicshttp://www.chalk-elec.com/1024x600 LCD) similar to the demo I purchased the *ULCD7 Lite* by CircuitCo http://beagleboardtoys.com at http://beagleboardtoys.com/wiki/index.php?title=ULCD7_Lite . Oracle engineers have been gracious in giving me advice while following instructions http://jdk7.java.net/fxarmpreview/javafx-arm-developer-preview.html(JavaFX Developer Preview for ARMhttp://jdk7.java.net/fxarmpreview/javafx-arm-developer-preview.html) to create an Angstrom build for the screen resolution of the ULCD7 Lite. To save on a lot of steps Gerrit Grunwald has created a great blog posthttp://harmoniccode.blogspot.com/2012/10/who-let-dogs-out.htmlwith detailed steps and also having links to an already built Angstrom image. I believe the only difference between my setup and Gerrit's is that the uEnv.txt (step 5) contains the following: vram=24M dvimode=800x4...@60 mem=99M@0x8000 mem=384M@0x8800 omapfb.vram=0:12M,1:8M,2:4M javascript: optargs=consoleblank=0 console=console=ttyO2,115200n8 mmcroot=/dev/mmcblk0p2 When finished with all the steps without any errors, you will notice the touch screen works in the window manager (*Gnome*). Having said that I'm not sure if it is actual native touch events or points converted to mouse events. Either way when you run a JavaFX application demo (*BouncingBalls*) the touch events aren't being received at all. When using your mouse to click in the JavaFX application window I'll notice mouse events work correctly. For those interested in low level touch events I wanted to point out an excerpt from the JavaFX Developer Preview for ARMhttp://jdk7.java.net/fxarmpreview/javafx-arm-developer-preview.html: *Note on Touch Display:* The JavaFX developer preview for ARM supports both mouse and touch input. However, many touch screens are not well supported by Linux. In order to work, the touch screen must have a Linux driver that creates a device file under /dev/input and sends EV_KEY, EV_ABS and EV_SYN events. The following touch screens are known to work: - 3M M2256PW - Chalkboard Electronics 1024x600 LCD display with touch screen for BeagleBoard xM. The 1280x800 model may also work, although the BeagleBoard xM might need to use a reduced refresh rate in order to drive this screen. I created this post as a Discussion and not a Question, because I want to (not only) learn but share with others on solving this ISSUE. Hopefully each vendor, community leader, hobbyist and/or OS software build expert can assist in integrating all these parts. Shown below is my parts list: *Hardware:* - BeagleBoard-xM (Rev C BB-XM-00), - ULCD7 Litehttp://beagleboardtoys.com/wiki/index.php?title=ULCD7_Lite(touch screen) - 16gb SD class10 card - 5v 2amp power adapter - USB (keyboard and mouse) *Software:* - Virtual Box (Ubuntu 12.04) - Angstrom - CircutiCo image Angstrom 01-11-12http://beagleboardtoys.com/wiki/files/ulcd7/BeagleBoard-xM_RevC1_ULCD7-Lite_01_11_12.7z - Gerrit Grunwald's blog Angstrom imagehttp://harmoniccode.blogspot.com/2012/10/who-let-dogs-out.html - JavaFX Preview sdk http://jdk7.java.net/fxarmpreview/ - JavaFX demoshttp://www.java.net/download/JavaFXarm/javafx_samples-8_0_0-ea-linux.zip Thanking you all in advance.

Re: [beagleboard] Remote debugging thru SSH
You are welcome and to be honest, i would go with what you feel most comfortable with. I have tried a bunch of different languages and personally prefer c++. I have found it to be the the most well rounded for my needs but those were my needs. I have not used python before so i can not say if it is better or not. It is basically just going to boil down to what you are comfortable and proficient with. Now please keep in mind that i have not done much programming in the last 10 years and i am sure things have changed since then. There may be better languages out there to use.

I'd also guess that your issue is related to power. Even though your BBB has a decent power supply, I'm betting that TI was very careful with power regulation for the USB host and it just will NOT supply more than 500mA of power[which is what it is clearly rated to for and which is more than enough for any USB compliant device]. Wheras if the producer of your your particular device was sloppy/didn't care they may need more than 500mA which most PC's these days will provide despite it being so far out of spec. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Remote debugging thru SSH
The problem with python in some situations is that it will use more CPU cycles, and can be horrendously slow compared to many native alternatives. Just a for example and very rough ( going from memory here . . .) C/C++ for one benchmark I looked at was around 7-8 seconds. ADA2005 roughly 12, nodejs(javascript) roughly 18 seconds, and lots in between but Python was somewhere around 80-90 seconds to complete the same task. Anyway this is obviously algorithm specific, and I do personally like python syntactically, but in a situation like this . . . yeah I'd most definitely go a different route. On Wed, Oct 2, 2013 at 5:34 PM, Wilfredo Nieves wilfred019...@gmail.comwrote: Actually i was thinking about this some more and i believe that an ssh tunnel would be a very good option. I would go about the configuration differently though. I would add a debug setting that the customer can enable and disable if they choose to do so. For instance if they enable it and then connect network cable then the device creates the tunnel and allows connection. If they disable it the device terminates the connection and closes the tunnel. This way if they decide they want their device to run wired then there is no concern about an open port on the network. Also a thought would be to have the system monitor the connection and if after say 1 minute there isn't a response it would automatically disable debugging or if there is a connection then set a timer for say 5 minutes this way it gives you time to look at the logs without having to worry about losing the connection. And possibly create a custom reboot script reboot debug which reboots the device in debug mode so that if you have to reboot the device remotely you don't have to ask the customer to turn debug mode on again. A plus about this is that you shouldn't have to worry about trying to figure out if it is connected to the network wired or wireless. You should be able to ssh in either way. -WIL On Wed, Oct 2, 2013 at 4:27 PM, monzie monzie9...@gmail.com wrote: Thanks for the links, very helpful. I take your point about privacy.

Re: [beagleboard] Changing cape from CAN to RS232
Sure, here it goes: First of all, the CANBUS, ProfiBUS, RS232 and RS485 capes from Beagleboardtoys all share the same PCB. It's just different components mounted, and different jumpers configured. So what I did to the hardware was to unmount the 5 jumpers connecting the CANBUS chips to the UART and connector, and instead mount them to connect the RS232 driver chip, which I also mounted. Yes, hand soldering 0402 chip components is not for the faint of heart, or for those with un-sharp soldering irons. I have plenty of experience and a MIL-SPEC soldering certificate So now the software part: The only thing that is important for the kernel cape manager is the board part no and revision no in the EEPROM. The EEPROM format is specified in the BB System Reference Manual, except for one thing that is missing: It says the part number is 16 bytes. If you have a part no shorter than 16 bytes you need to pad it with . characters. I wanted to use a .dts file that was already available in the Angstrom distribution, so I called my cape a BB-UART1 of revision A0. I had some trouble trying to edit the eeprom directly, probably because the editor tried some smart way of saving that a Flash memory driver didn't like... so I made a copy, edited, and then copied the content back: cp /sys/bus/i2c/devices/1-0054/eeprom ẽeprom vi -b eeprom make edits in Replace mode cp eeprom /sys/bus/i2c/devices/1-0054/eeprom The copy into the eeprom takes a LONG time. I2c is not a fast thing... Also notice I used vi in binary mode. You can use any binary file editor, even hexedit :-) Now with a correct board part no and revision the kernel will automatically load the driver at boot.
