• Toolkit of Real Time Execution Trace functional limitation on targets NI Linux real time taken in charge

  We want to start by using the Toolbox in real-time to backtrace of memory allocation profile on a target of cRIO 9035 & 9039.

  The product information (http://sine.ni.com/nips/cds/view/p/lang/nl/nid/209041) page has a note indicating that the Toolbox has limited functionality on real-time OR-Linux supported targets.

  However, I couldn't find any specific details about what are these limitations.

  If anyone can clarify which restrictions apply?

  Are there alternatives (party packages) that offer a feature more complete?

  Hello Jörn,

  Did some more research, the following limitationrs occur on targets LInux RTOS,

  -The Manager of memory when used on targets of Linux, saves only data for LabVIEW processes and threads, not the global memory of the systems.
  -Wait object are not recorded events
  -Trace buffer size cannot be changed
  -Timed loop pre-emption and reactivation of SRI events are not marked

  Hope that this information helps out you in addition,

  Kind regards

• Create a shared library for NI Linux real-time

  I need to build a shared library for NI Linux time real (.so) which corresponds to a shared library, which I create on Windows (.dll).

  I have the C code that needs to call a function of VI. On Windows, I have a project that allows me to create and build a "Shared Library (DLL)", but I don't see the same option available in a real-time project targeting the cRIO-9068. Am I missing something, or is it not still possible?

  Hi Wayne,

  Using LabVIEW VIs in other programming only possible through dll environments. In LabVIEW there are options for creating libraries and source, but these distributions will be accessible in LabVIEW and not in other programming environments.

• How to create the shared library for linux real-time target in labVIEW Windows?

  I use myRIO running linux in real time. In my project, I need to pack some C code, so I tried the node library function call.

  I know that I should use the tools compile cross - compile linux on Eclipse to compile c code in linux .so library. But the problem is that call library function node does not recognize the .so file because my labVIEW runs on a Windows PC.

  What should I do to fix and how to combine C code with labVIEW during programming for devices shipped as myRIO?

  Basically, you must also create a Windows DLL that exports the same functions. These functions can be empty stubs if you do not want to run the code correctly on Windows, otherwise you will need to consider how to implement the equivalent functionality on the Windows API.

  Then you can write in your node library call as the name of the library ". "*" and the name of the shared library Windows ".dll" while the Linux version is called "name of your library > .so". LabVIEW will replace the * after the comma in the name of library with everything that is the preferred extension shared library for the platform it is running on and therefore load the right shared library.

  Alternatively you can wrap call all the nodes of the library in a structure that contains the node library in the case of Linux RT and all what you want to run on other platforms in the case of default or a case of specific platform, call the conditional compilation.

• On a Linux operating system, what tools need to developed a real-time application that communicates with FPGA?

  On a Linux operating system, what tools need to developed a real-time application communicating with FPGA?

  It is not unclear to me by reading the documentation on the website OR tools or drivers should I install on a Linux operating system in order to develop a C++ real-time application (that interact with FPGA) which will take place on a sbRIO-9651.

  Is this possible at all?

  Everything works very well with an FPGA VI, compiled with LabVIEW FPGA 2015.

  1. I have installed Eclipse on CentOS 7 with cross-compiler found at this link:

  Compilers C & C++ GNU for Linux ARMv7 (Linux host) 2014

  2. I also install a debugger crossed to debug application c / c++ remotly. Once on the page go in the section "Linaro Toolchain for Cortex-A" and download the second link linux "linaro-toolchain-binary (big-endian).  The binary gdb is in there, so you must point towards him in the Eclipse debug configuration:

  Linaro Toolchain for Cortex-A

  3. I installed the linux drivers from NOR-RIO 15:

• Get strange errors 'real time' in the browser console, what do mean?

  I noticed recently that since yesterday is the day prior to that, I get a strange 'real-time' error messages in my browser console log. I get them for more or less the same sites, and I have attached a screenshot of some of the most common mistakes for example. I see these errors very frequently in the browser console log.

  So I'm a little worried about what mean these errors, why I want to come and if anything, what to do about them.

  Hello

  Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

  If Firefox is open, you can restart Firefox Safe mode in the Help menu:

  • Click the menu button

    

    click Help

    

    then select restart with disabled modules.

  If Firefox does not work, you can start Firefox in Mode safe as follows:

  • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
  • On Mac: Hold the option key during the startup of Firefox.
  • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
    (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

  When the Firefox Safe Mode window appears, select "start mode safe."

  

  If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

  When find you what is causing your problems, please let us know. This might help others with the same problem.

• Dysfunction of real time on Satellite Pro C650

  Hello everyone.

  This is my first time on the site.
  I have a Satellite Pro C650. I have had it for 3 years now & everything is going well except the real time.
  Real time shows dozens of yellow folders that contain content zero. As I remove them one by one, they disappear, but the program stops during the removal. Then they reappear next startup.
  I am running version 1.6.06.32.

  Any help would be great.
  Cheers, Glen.

  To be honest I don t use real-time, but have you tried to reinstall?

• Satellite Pro M30 - real time clock shows wrong time

  Hello!

  most of the time I am using my Toshiba satellite pro m30 without the battery with the energy of the power system. the battery is stored somewhere outside of the computer for a month the real time clock shows a bad time if the computer is started after a period of time.

  I think my cmos battery is going to die soon.

  someone has an idea, how this cmos battery can be changed by myself?

  Thank you
  Reinhard

  Hello Reinhard

  I agree with you. It is time to replace the CMOS battery. It is not easy and the machine must be dismantled. If you are not familiar with the procedure for disassembly, it can be dangerous. A small mistake can result with damaging material.

  If you want to do it alone, you do so at your own risk. Be sure to use the right battery. Maybe you won't believe, but if you use a battery hurt it could cause battery explosion, or other damage.

  I'm not 100% sure, but the RTC battery must be placed on the left side near the touch pad. If you want to only please be very gently. The laptop parts are very sensitive.

  Hello!

  Unfortunately, this feature is only available with the GoPro cameras.

  And Yes, if all cables already existing for these purposes, it would be kind of a pain to take pictures and do not shake the camera accidentally. Maybe, VSCO camera makers will make such feature in some time in the future. This idea is excellent and innovative. Maybe even Apple will listen to users and make their new iOS 10.

• Debugging on a real-time target - deployment issues

  Dear community,

  After RT my 9651 sbRIO module wiring code, I do tests to check the intended functionality. For this I start my main VI who deploys the code on my SoM and I can happily move forward with my debugging session.

  Sometimes, however, while in the process of deployment, I get an error saying:

  [VI - name] .vi loaded with errors on the target and was closed

  When I open the VI it has no errors and the VI should work a fine might think.

  My solution was so far of the VI, just open move the wires and terminals round, re - save the VI and this is the deployment works.

  This trick worked for a while, because deployment error ca occur arbitrarily on different VI making debugging quite cumbersome.

  I then went ahead and just run the wrong VI in RT mode by moving terminals and structures around to get the VI runs in mode debugging, but it is very time consuming.

  Given that 3 people working on this project and we use git-subversioning I also do not want to "touch" each time just screws for the debugging session will without actually modifying the feature.

  Has anyone encountered a similar experience or perhaps found a magical setting to avoid this subject a lot of time?

  Hello

  If solutions already present Spex does not do the trick for you, clearing the cache of the compiled object can help.

• Real-time execution trace toolkit to optimize the Labwindows/CVI code

  Hello

  I am trying to optimize a code in real-time in LabWindows/CVI by minimizing the time of each section of the code is taking and find bottlenecks in the code. I check this time using the real-time execution trace toolkit.

  However, I just found it seems to be a constant error when you use the tool of real-time execution trace.

  When I put the traceviewer 'start' and 'stop' right after the other, I get around shift schedule 9us. It seems that the CPU will in some "idle" after the start of the trace mode, or maybe it's the time of communication or something.

  I'd appreciate it if someone could give me an idea of why this is happening. The time of real-time application window is very limited and I'm trying to minimize the time as much as possible. Even the United States 9 error is difficult to resell.

  I used the following code:

  TraceConfigure (1, 1, 0, 25000, NULL);
  
  TraceStart ();
  
  TraceStopAndSend (HOST_ADDRESS);

  and there is a photo in the toolkit of real-time execution trace.

  Thank you.

  Generally, you might be better off picking off the clock at the beginning and end of what you want to track. RTETT my introduce overhead that becomes difficult to quantify... Which is what you probably already see. The debug mode will also implement a ton of overhead. Then... Destemming of the clock in release mode will probably give you you the best estimate.
