FPGA Module: Global Clusters become Locked after Compile?

It seems as if, on some occasions, global clusters become locked after a successful compile of a project - you can't enter edit mode in order to add new elements to the cluster. I haven't been able to lock down the circumstances under which this occurs, but it has happened to at least two projects I've designed.
This is a major heartache, as the only solution I can come up with to add new elements is the following:
1. Create a new cluster.
2. Include all existing elements of the locked cluster as well as your new element.
3. Reset all Variable Representations and Data Ranges.
4. Replace the locked one with your new cluster for all instances in the code.
Is this a bug, or is this simply a limitation in the program? Does anyone know of a simpler way to solve this issue than my solution above?
Thanks,
Dan Price

Hello Dan,
I was not able to replicate the issue. Here is what I tried
1. Created a Global variable
2. Used the global variable in my FPGA program.
3. Compiled the program
4. Added elements to the global variable and saved it.
5. Updated my program and compiled it again.
If you can suggest another way to replicate the issue or attach your VI's I will try replicating it. If you think it happens occasionally then we should be able to narrow it down to specific circumstances to troubleshoot.
Thank you and have a good day
RMM

The pull down menus at the top become locked or frozen and unselectable after some use of firefix. When I restart it is fine again for a while. Also I cannot type into the url bar when this happens. I have never had any problems before with firefox so I hope this can be remedied!

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

Crash at compilation/Intermediate files generation LV FPGA module

Hi.
I'm in desperate need of assistance.
I have been using LabVIEW 8.6 with FPGA module running at Win XP for som time now and I have never encountered any crash while compiling before.
I get one of those Error messages where I just can send an error report to Microsoft.
I use the FPGA target RIO0, PCI-7833R and have designed a FPGA interface-VI including a number of functions. When I right-click at the VI and choose Compile, generation of Intermediate files begins. Now I never get further than the before LV crashes. Each and every time.
I have no problems opening the project file or my FPGA VI, updating them or saving them.
Grateful for help. Thanks!
/Henrik

Hi!
Thanks again for good ideas. Unfortunately it didn't help repairing. I tried with both FPGA Module and the FPGA compile server (even though the compilation process never reaches that far) without success. I even tried to repair the whole LabView 8.6 but with the same result.
Even before repairing I have been able to make another small VI work its way through the whole compilation without crashing. But when I replace the small VI with the previously "failing" VI, it crashes again. I have also tried to cut away most of the functions of the VI but it still crashes.
Is it possible that I have some kind of bad reference, some missmatch when instanciating and mapping any of the VHDL nodes or something like that that causes the crash? Still one would think that this should generate an error in LabView rather than generating a "windows crash", but maybe something can cause the file generator to fail completely. It has been working before and I did a very small change when the crashes started, but something is obviously wrong, so...
Since its crashing even before connecting to the compile server, do you think I can rule out any damage/failing on any of the HW (e.g. the National specific HW and my external board and the on-board FPGA? Since I'm running out of ideas myself I guess I could look into that as well, but I can't see that that's the problem.

Apart from the lock button problem in iphone 5 the display brightness suddenly goes blank and becomes normal after locking and unlocking the iphone. The Apple service centre in India is denying to service the iphone as it was purchase in USA even thoug it

Apart from the lock button problem in iphone 5 the display brightness suddenly goes blank and becomes normal after locking and unlocking the iphone. The Apple service centre in India is denying to service the iphone as it was purchase in USA even though the iphone is in warranty.

iPhones do not have an international warranty. Warranty is valid only for the country of purchase. This is most likely because different countries require different iPhone models. Not reasonable to expect all countries to maintain stock for all models.

No option to simulate cRIO device after installing Labview and RT/FPGA Modules from downloads (missing driver support?)

Hi guys--
Basically, I need to simulate a cRIO device without yet having the hardware on hand, like this:
How to Simulate FPGA Hardware Targets Using the Project Explorer with LabVIEW
Instead, I only get the options shown in the attachment "Add Target Options.jpg". I assume this is because of missing drivers, which I assume is due some mistake I made during a recent fresh install of LV. The install went like this: I downloaded (not disks) and installed the following (in this order, latest versions all around):
(1) LabView Development System
(2) Real-Time Module
(3) FPGA Module
(4) NI-RIO (install prompted by previous install)
(5) DAQmx
At the end of (1) and (2), I got the screen shown in the second attachment ("Drivers Install Message.jpg"), but could not get it to recognize the "NI Device Drivers" folder (which I also downloaded), or any of its sub-folders.
I feel I'm missing some obvious option for loading up the necessary drivers after the install, but can't seem to find reference to it in the forums. Could anyone give me a little push in the right direction?
Thanks a bunch, and have a great day.

Michael--
Thanks for your reply. In answer to your questions, the DAQmx install seemed to go smoothly, and I believe this is evidenced by available my MAX Simulated Device options (shown in the attachment to this post). My best guess (could be wrong here) is that I cannot simulate a cRIO device because I was unable to install the drivers after the Real-Time Module installation (as described in my first post).
The source path selection screen for drivers ("Drivers Install Message" attachment in first post) told me "...you can install NI device drivers later.", and since it would not recognize anything in the NI Device Drivers folder I downloaded, I clicked on "Later".
I could narrow the issue down a bit if I could now install those drivers, but this is my first time installing without disks, and I can't figure out how to properly install the drivers from the folder I have sitting on my hard drive. Have I overlooked instructions somewhere on this procedure?
Thanks a bunch for your help.

After installing iLife Support 9.0.4 - network login becomes locked

I'm experiencing a strange issue after installing iLife Support 9.0.4
I am on a corporate network using Active Directory. I use Connect to Server every day to access all my files for work.
Here is my scenario:
1. Startup OR Restart my MacBook
2. Login to my user account
3. Finder -> Connect to Server (i.e. smb://server/location/etc/)
4. My network credentials are saved in my keychain, so it tries to connect
5. My network account becomes locked.
After #5 I have to call our Help Desk to unlock my network account.
Once my account is unlocked, everything works fine - I can use Connect to Server, Entourage email, etc.
Unfortunately I am unable to use Time Machine due to our company policies
Any insight would be appreciated.

I just dragged all of the 1 January 2001 Prefs out of my folder and restarted and it looks like its working, including the keychain. I'll keep monitoring this...

Does an iphone4s become locked to the SIM card that you insert after you follow the steps given to unlock the phone? Thanks a mill

Does an iphone4s become locked to the SIM card that you insert after you follow the steps given to unlock the phone?
I just received the steps by email from meteor and I'm moving to OZ in September. I have the OZ SIM card I intend using over there but I don't want to end up locking the whole phone to the OZ network before I go there.
Any help on this matter would be greatly appreciated

That only happens when you purchase a supposedly unlocked phone from specific stores that say their unlocked but as soon as you insert a sim card they lock to that carrier... a trick (sort of)... that's something totally different than what you are about to do!

My iphone 4 become carrier locked after update

My iphone 4 become carrier locked after 4.3 update i now update to 4.3.5 but still the same, is this possible??

I've recently discovered the same problem with my old 3Gs. Having purchased a 4s I gave my old 3Gs to a friend who's been having trouble with the dreaded 'Incompatible SIM' message.
It was bought unlocked direct from an Apple store when the 3Gs was released, as I was still in-contract on my original iPhone 3 and so I just swapped the sim over and when my contract was up switched to a cheaper sim-only deal.
As far as I can tell it's become locked through one of the subsequent software updates (including developer betas) but I've no way of knowing that for sure.
It's massively frustrating now as Callum has the phone but can't use it as he's not with O2 and they say to unlock it, it will need an O2 sim installed and may take up to 2 weeks to unlock. Well I no longer have a regular O2 SIM as I switched to a micro sim for my 4S and can't be without that so it looks like I'll have to buy a PAYG sim which I'll never use except to get it unlocked which i think is rather unfair as I bought in unlocked in the first place!

NI LabVIEW 2013 FPGA Module Xilinx Tools 10.1 Download Troubles

I am trying to download the Xilinx Tools 10.1 to use with a 9113 chassis in LV2011. Based on this white paper the compiler below should work just fine. The problem is I can't get it to download all the way.
I can't seem to get past ~336MB using the standard or NI downloader. Any ideas? Anybody else having this problem?

Well... on the bright side, you don't want 10.1 anyway!
Virtex-5 LX50 <- REQUIRES Xilinx 14.4.
10.1 is only for Virtex-II devices! (...after LabVIEW 2009 that is, just so everyone reading this knows).

RT & FPGA Modules – I am missing a fundamental concept

Recently I have been asked to program a compactRIO 9074 and in the midst of researching how to do that, I have become thoroughly confused…
I understand that the RT module is used for precise timing (i.e low jitter) and somehow it interfaces with the host computer (i.e. computer with the VI). I also understand the FPGA module allows you to, and forgive the simplicity, recreate the circuit on the chip, thus allowing virtually true multithreading and really fast speeds. Also, the FPGA interacts with the IO modules/ports.
The thing that I am unclear about is:
When you program the compactRIO 9074, do you select only one module (RT, FPGA) and ignore the other?
-or-
Do you use both modules - the RT module for the embedded hardware and the FPGA module for the FPGA bitstream? If so, how does the embedded hardware talk to the FPGA? Is this something you have to manually program? Any literature/tutorials on this?
-or-
I’ve even read something to the effect- the embedded module gets programmed with the RT module when the cRIO boots up for the first time. If that’s true, then does RT module get used only that only time and all programming thereafter is done with the FPGA module? Is the one-time RT module provided by NI or is this something I would have to create?
I think that I am missing something so fundamentally simple that this whole project is becoming so unnecessarily complicated.
Thanks in advance for the help.
Joe T.

It is a bit complicated, but powerful and flexible. If your needs are simple, NI provides tools (such as the scan engine) so you may not need to get into all the details.
The cRIO is almost a full computer, running a dedicated, real-time operating system (either PharLap ETS or VxWorks, depending on your cRIO). On top of that, there's the LabVIEW runtime. That computer also contains an FPGA, similar to if you bought one of the NI PCI FPGA cards and installed it in your PC.
The FPGA talks to the processor in the cRIO. If you need full control over the FPGA, then you write that code yourself and use DMA FIFOs and front-panel controls to transfer data between the cRIO and FPGA. If you just need access to the IO, you can use the Scan Engine, as previously noted. You also need a way for the cRIO to talk to your computer. Again, you can write code yourself, or use the NI-provided tools such as network shared variables. If you don't need the cRIO to do anything other than act as an expensive data acquisition device, you can link a shared variable to an I/O channel and access it directly from your PC, or share your IO variables over the network. Run a search on the NI site for "network shared variable scan engine" for more information.
You write separate code for the cRIO and the FPGA. You can run your VIs on the cRIO within the LabVIEW development environment and use most of the standard debugging tools, it will just be a bit slower to respond than when the LabVIEW code runs on your PC. When you have a working program, you can build an application and deploy it to the cRIO so that it will run at startup. You can do this as many times as you like. The LabVIEW program on the cRIO may contain an FPGA bitstream embedded in it. Writing code for the FPGA is more complicated - there are limitations, and you must compile the code before you can run it (no interactive debugging unless it's running in simulation).

How can I install (download) a Labview FPGA code onto Altera FPGA chip using Labview FPGA module?

Hi there
Guys i'm a very new labview user (PhD student), my project is about ( design and implementation of a high speed-yet sophisticated system using Labview environment then install this project's code (using Labview FPGA module) onto Altera-made FPGA chip).
so kindly, can any body help me in this?...is there any way to connect labview with Altera FPGA?...please anything would be said 'd be of great benifits
thanks a lot in advance.

as previously mentioned, labview fpga only supports national instruments targets utilizing xilinx fpgas. the hdl generated by labview fpga is encrypted and cannot be used to synthesize a design outside the labview fpga design flow.
however, if you must use labview for your project, it might be possible for you to design the system in labview and use one of the labview embedded modules ( http://www.ni.com/embedded )to generate c code which you can then port to systemc and compile for the altera fpga. i'm not saying it will be easy, but it should be possible.

Multiple Digital Signatures in Adobe Acrobat XI - PDF locks after first signature is saved

I am working with a fillable pdf that was set up by an administrator to have multiple DIGITAL ID/SIGNATURES inputted, i.e. it does not allow images of signatures or text; when you click on the signature field, it ONLY prompts the insertion of a Digital ID. This form requires multiple signatures and editing/text from diverse people. I need to sign it and then circulate it to these other people. For some reason, when I insert the first digital ID and save it, the pdf becomes locked - it is no longer fillable, and no one else can edit or even insert their own signatures. What can I do to allow editing/additional signatures to be inputted after putting in my signature and saving the document? PLEASE HELP.

I don't know where I could post it...Could you please tell me how I might check if signature fields are set to "read only" or not? I have been looking through this pdf for so long and I don't even see the option to do that. When I click on the signature field, it just prompts me to insert the digital signature...there isn't much information displayed at all.
