• How to get the console on cRIO based on linux?

  Hi all

  I develop new things on a cRIO 9068. This cRIO runs Linux RT.

  I built a framework of cRIO app and use for several years, I use the console to debug my code and have the status of my displayed cRIO.

  I can't find a way to see the console with the 9068 when I send strings to it (see the simple example attached to this post).

  Can someone help me see that I send to the console?

  BTW: I do not want to write debugging on the serial port, only to watch channels.

  In fact, in order to obtain the result (which is for the port series, either through the exit option "monitor" that requires activation of the console series see, or the serial port as usual without configuring the console out) to be visible, the network, there is not a great, simple way to do a little more ethernet today.

  One option you have is to change how lvrt is launched to save to a file and to access this file (either from lvrt, webdav or ssh), wrote messages on the screen. It is a more down-n-dirty approach, but he could get the results you wanted.

  Change the /etc/init.d/lvrt-wrapper or/usr/local/natinst/labview/lvrt-wrapper file to channel the monitor console to a file

  (note that brackets [] denote a touch, the lines that begin with / / are notes and does not have to be entered)

  VI/location/of/lvrt-wrapper

  Go to the line that looks like 'exec. "/ lvrt.

  [i]

  Add the following code at the end of the line

  [space]>[space]/home/lvuser/lvrt.log

  [:] [w]

  The line should now look like 'exec. "/ lvrt > /home/lvuser/lvrt.log.

  Restart your target, check the contents of the file with "cat /home/lvuser/lvrt.log.

• reboot Linux cRIO

  I have a distributed system. There are Linux, Windows and 9104 cRIOs machines. I want to know if it is possible to restart the cRIOs from the Linux server. Each target runs an application in LabVIEW 8.5.

  The obvious solution would be to write the actual code restart in cRIO and code as the Linux server to send a message. I don't want to do it for several reasons.

  A second solution would be to write the reboot code to execute on the target windows to restart remotely the cRIO. I'm not especially for this either. (It's kludgy and around.) The Linux server throws the message to the windows computer, which then send the message to the cRIO).

  Is it possible to restart a cRIO remotely from a Linux machine?

  Hey 2verb,

  I think the best way to write the code to reset on rio and send a message from the linux machine via tcp, udp, or a different protocol. Could you explain why you don't want to do?

  The windows machine, you can use the configuration api system to restart the target. This point is under the measure e/s > system configuration > software time real configuration > reboot.vi however, this API is not available under Linux. I'll look into linux or not has a different method for sending this command.

  Thank you

• Call to a shared library a VI on a target NI Linux RT (cRIO 9068)

  Hi, I wrote a very small shared library (.so) with Eclipse (toolchain 2014), which essentially serves as a wrapper for more complex, but I am having problems with the call go to in LabVIEW RT on a target Linux RT - specifically, the cRIO 9068. First: the library was copied in/usr/lib and ldconfig has been correctly implemented. More important yet, I have also written a C program (using Eclipse as well) that calls the single function currently implemented in the shared library: this works perfectly, both in Eclipse and you connecting directly on the cRIO with a Putty terminal. So I guess the shared library itself is ok and can be called from code/external programs. Now, dating back to LabVIEW (2014 here btw). Here's where things get difficult, I guess. Initially, I had the symptoms listed here--> http://forums.ni.com/t5/LabVIEW/How-to-create-a-c-shared-library-so-for-linux-real-time-for/td-p/302... who prevented me from actually run any code on the target of RT. Then I changed the call library function node: various tutorials suggest to put name_of_library.* in the path text box or the name of library, but unfortunately it doesn't seem to work, so I had to put the name and the extension too. But it still produces the error below ("the name of the function is not found" etc.) So I check the box 'specify path on diagram' and add/usr/lib as a parameter to the node library function call: now the VI can work and is actually transferred to the target of the RT... but the cluster of output error returns error 7, which is a kind of "File not found" error. However, I believe that this error message is misleading: indeed, if I try to debug remotely this library shared under Eclipse, I am actually able to pause it. and when I press the Pause button on the debugger, the goal of RT VI pauses, then continues as soon as I press the Resume button, I'm stuck... I tried searching forums and Google as well, but I have not yet found a solution. Any ideas on what's going on? Moreover, I can add more details if needed.

  Problem solved, it was a bad configuration of the node library function call which prevented the actual library (.so) to be called.

• FTDI interfacing with myRIO RT Linux

  
  

  Hi fahad80,

  1.) make sure you have installing NI VISA USB Passport on the myRIO (I realized I had not checked it in the picture)

  2.) go from MAX, right-click on the myRIO under systems remote and select "transfer files".

  Then, go to:

  usr/local/vxipnp/linux/NIvisa /.

  Open the visaconf.ini file and add the following tokens [ASRL-RSRC-ALIAS] section:

  Name3 = "ASRL4::INSTR."

  Enabled3 = 1

  Static3 = 1

  SystemName3 = "/ dev/ttyUSB0 '.

  BaudRate3 = 9600

  Parity3 = 0

  StopBits3 = 10

  DataBits3 = 8

  FlowCtrl3 = 0

  NumOfResources = 4

  3.) then restart the device and use PuTTY SSH in the myRIO

  4.) then we will have to use this command in Terminal:

  chmod o + rw ttyUSB0

  5.) MAX refresh/restart to check if the serial port is displayed and is able to communicate and if not, try to restart the myRIO

  I would like to know what are the results of that.

  Kind regards

• Make a local copy of repo OR Linux RT cRIO

  I'll do a repo wget OR and add an alias in my dns server. As this download.ni.com show up on my local server. It will be transparent for the cRIO.

• Problem of memory TDMS on cRIO-9035 (Linux RT)

  Hello

  I was unable to move in a kind of memory problem that I am experiencing during written TDMS. I write in the PDM file, use of the RAM on my RT goal grows regularly. I thought it was due to some kind of indexing that happens with very large TDMS files so I am currently split my files at the level of the 50 MB mark. When the maximum size is reached I empty and close the file, and start a new one. So when I stop recording I rinse and close the bottle. However, use of the RAM of my continuing to increase anything.

  I've read about it and I've seen repeated references by using the NI_MinimumBufferSize property as a possible solution. I've implemented this, but it doesn't seem to do the trick either.

  Everyone has been able to overcome this problem, or I'll have to return to the spreadsheet of construction VI (please no.).

  I've included a simple set of VI that initializes an array of 16 x 2500 to simulate values 2500 for 16 channels and writes this table to classify every 50ms. In my real application table 16 x 2500 are 16 channels playback at 50 kHz readings of my analog input module. The "RT_TDMSMemoryIssue.vi" would be the main VI launch.

  Thank you

  It's probably the file system buffering of i/o to files in memory. Depending on your version of LabVIEW, LinuxRT reports of memory can include these as "used" memory buffers when they are actually available to applications on request.

  There is a document which deals with it here: http://digital.ni.com/public.nsf/allkb/AC6200D19D23C61586257C8D006E6DC2?OpenDocument

  My main question is do you ever see a memory error output? What happpens if you expect that the memory fills up?

  I expect that you will see the behavior where the memory appears to fill, but any work properly!

• Can I use a USB storage in a cRIO-9064?

  Hi all

  For a project I need to have more storage space on a cRIO. I'm currently looking the cRIO-9064 with USB port.

  Is it possible to connect a USB mass storage device this port and use it to IO files?

  PS. I am aware of the c modules that offer an sd card slot, but my budget is high enough for the latter.

  PPS. If you have examples of code, you can quickly spent in your answer would be great.

  Sandra will be given.

  Thank you

  Hi Freel, it is possible with all the objectives of the RT that have a USB device port. The USB key will be mapped to the target of RT U drive. The cRIO-9064 running the Linux RT operating system, so you will need to use the notation of oblique way. See this article for more details:

• Unable to write to the directory root on cRIO

  I need to create a folder in the root directory of my cRIO but when I try to do it via the web interface (Silverlight) it gives me an error 403 (refused).  I can create and edit files and directories in existing files located in the root directory.

  The seller has managed to create a new folder in the directory root on our previous cRIO, but now we are trying to set up another one on our own.  They told me that they don't have to do something special that they do not forget to create this folder.

  Any ideas as to why I wouldn't be able to do this, even if I have all permissions on the device?

  It's confusing, but "all permissions" web interface are only "all permissions for the web server has permissions for things", that's not all. See http://digital.ni.com/public.nsf/allkb/4EBE45E8A816B19386257B6C0071D025 - more precisely:

  Write access

  (ETS, VxWorks) Your target provides write access to its folders and files.

  (OR Linux in real time) If you want to modify or create new folders and files on your target, you can only do in the following directories:

  • /home/webserv
  
  
  • /home/lvuser
  
  
  • /tmp

  Note: Your target deletes the content in the temporary folder /tmp on target restarts.

  Restricting access to the root directory makes the system more robust (prevents the change of important system files).

• Advanced Signal Processing Toolkit and cRIO

  Hello

  I have a cRIO-9030 with two NI 9223 modules, and I need to use the Advanced Signal Processing toolkit on the RT target to do transformations of wavelets on the input signals. I loaded the libLVASPT_WA.so on the cRIO file in the folder/usr/lib, but I get the following error when I try to run my code: "NI_AdvSigProcWA.lvlib:wa Polyphase filter.vi loaded with errors on the target and has been closed." (see attachment). It seems that the AdvSigPocWA.lvlib is deployed successfully for the other vi, it seems that the cRIO is at least to see the library. According to what Wavelet I select, it's wa Polyphase filter.vi or WA Interpolation Filter.vi that causes the error when I use WA Denoise.vi. If I use another VI WA I get always similar errors but then for different vi. I tried to create an empty project with just a vi WA but I still get the same error, so it doesn't seem as if the rest of my code is having an effect on this. Any help would be appreciated.

  Kind regards

  OK, so the cRIO-9030 runs a Linux RT of 64-bit operating system, which is not compatible with the current v15.0.0 Advanced Signal Processing Toolkit. So the only solution at this point is to change the material until NEITHER has solved the problem of compatibility.

• cRIO 9067 to hired 7fh USB RS232

  Hello

  I have a cRIO 9067 and would like to interface with an instrument that has a converter USB-RS232 from SiLabs.  I can't comminicate with this instrument easily on a Windows PC.  I am able to see the device in MAX when its the cRIO connection.  IT appears under "Devices and Interfaces" as "USB0::0x1FB9:0 x 0100: 121A00A:RAW ' with model number and description of the device.

  I followed the description at this link, but I don't get a ttyUSB # devices.

  https://decibel.NI.com/content/docs/doc-34827

  Is it possible to get this working on the cRIO as a serial port?

  Thank you.

  After some research, talk with people, NOR google and to talk with people to lakeshore.com (provider of the device) this is what I have reconstitute on how to make this work:

  • Under Linux, usb devices are listed automatically, and by default, will appear as a USB RAW device
  
  
  • Once the USB device has been identified, it can then subsequently be linked to a driver
  
  
  • Linux determines if and when to link each device USB-based device Vendor ID (VID) and the model identifier (MID). It is usually 3-4 digit hex string.
  
  
  • In the case of the Lakeshore 121 power source, VID = MID 1FB9 = 100.       I could see in MAX for the Raw Device USB.
  
  
  • There are two levels of USB-serial device drivers. The first pilot: usbserial.ko is a generic driver that handles all USB-serial devices. This should be loaded for any USB-serial converter.
  
  
  • The second driver is specific to the chipset for the USB-serial device.       For the cRIO, there are three options which are pre-installed (DFT, 7fh and a few others)
  
  
  • The drivers can be found at /lib/modules/3.2.35-rt52-2.0.0f0/kernel/drivers/usb/serial/ (where the kernel version directory may vary)
  
  
  • Lakeshore 121 uses the TR labs CP210x chipset, so we chose this one.
  
  
  • Records of the device first of all need to be loaded by Linux. Linux can automatically do this by adding files of length zero in the module.autoload.d directory. To do this run the following:
  
  
  • CD /etc/modules.autoload.d
  
  
  • Touch usbserial
  
  
  • Touch cp210x
  
  
  • restart cRIO
  
  
  • run dmseg. grep usbserial to confirm that usbserial driver is responsible
  
  
  • run the dmesg | grep cp201x to confirm that the driver for cp210x is loaded
  
  
  • The next step is to associate the cp210x of our device USB device driver. Don't forget that linux associate unit to a pilot from the VID and moy. anyone installed linux cRIO base, I'm sure, knew nothing of the VID 121 Lakeshore and MID.
  
  
  • Lakeshore recommended to read the source code for cp210x, adding the VID and MID to the list of recognized devices, recompile the cp210x.ko file and install it on the cRIO. It would work, but it is beyond my current Linux capacity.
  
  
  • Linux offers the possibility to dynamically add MID, VID, so that a device can be recognized on the fly
  
  
  • When the driver CP210x is loaded, a struchture of the entire directory is created. There is a file because the directory structure called new_id where you can dynamically added VID, mid
  
  
  • Create a startup script to run the following command. Be aware of the problems of termination of cr/lf line between operating systems. It is generally easier to create the script on the cRIO with the VI editor to avoid any problems.
  
  
  • echo 1FB9 100 > / sys/bus/usb-serial/drivers/cp210x/new_id
  
  
  • Startup script Info: https://decibel.ni.com/content/docs/DOC-38960
  
  
  • Now, restart (or running the script), you will get a device/dev/ttyUSB [0-9]
  
  
  • Unfortunately, the creation of default of the unit ttyUSB [0-9] does not permission to write, so we have need create a UDEV rule to automatically grant writing
  
  
  • Add the following lines of code udef.conf in the folder/etc/udev

  #typical devices

  ttyUSB [0-9] * root: ATS 666

  • Create a file named 99 - ttyUSB.rules in the /etc/udev/rules.d folder
  
  
  • Add this line of code in this file:

  KERNEL == "ttyUSB [0-9]" * ", OWNER ="admin", MODE ="0666""

  • Restart the cRIO. This should be it! It worked for me.
