How to fix error for LMH1982 Eval kit software on startup for Windows 10?

Other Parts Discussed in Thread: LMH1982, LMH1981, LMH1982SQEEVAL, LMH1983

I'm getting an error running the LMH1982APP-SW software on Windows 10.  After installing in the default location, I start the program and I get the error message before the program launches.  You can see the error below: "LMH1982_New has stopped working."

I have this eval board plugged in via USB:

LMH1982 Multi-Rate Video Clock Generator with LMH1981 HD/SD Video Sync Separator EVM

http://www.ti.com/tool/lmh1982sqeeval

I've tried on two separate computers, different USB ports, uninstall/reinstall, and rebooted the computers.  I've verified the USB cable is good by using it with some camera hardware I have.

Thanks for he help,

~D

    Hello,

    This is a mature product (circa 2008) so the EVM software may not be Windows 10 compatible.

    Could you please try to run the program in Compatibility mode for Windows XP?

    Thanks,
    Alan

    The program fails the same way when running in compatibility mode for Windows XP.

    Also, I need the schematic and layout for for the eval board lmh1982sqeeval: www.ti.com/.../lmh1982sqeeval Documents

    Hello,

    The LMH1982 schematic/layout are in this doc: 

    Regarding the software GUI issue, you may need to "disable driver signature enforcement" in Win10 to allow proper installation and open the GUI software.

    See here:  

    Other resources on this topic could be found via search engine.

    There is no plan to develop a new GUI+USB driver with Win10 compatibility.  If disabling driver verification in Win10 does not work, I guess the only option may be to install/run the software on a PC with WinXP or Win2K.

    Alternatively, you may consider the LMH1983 instead, which has more features, or similar jitter-cleaning clock generator device from our LMK04xxx family.  If you can provide your system clocking requirements, I can provide some recommendations which have more current software tools.

    Regards,
    Alan

    I noticed it is in that PDF as well, but I would like to import it into Altium. Do you have a format other than this PDF I can use? Or do you expect your customers to recreate your schematic and layout?

    I tried disabling driver signature enforcement. Then I uninstalled and reinstalled the program and I am getting the same issue. I don't have access to Win-XP. My preferred operating system is Linux Ubuntu, but we have a few Win10 licenses available.

    Does the LMH1983 have an eval board? This board is nice because I can access the SD/HD clocks and TOF pin genlocked with a reference generator from a cinema camera. If you had an eval board for the 1983 I would be interested.

    LMH1982 is an older product, so the schematic/layout are not available in Altium/CAD format like more recent products.

    I recommend you post a new E2E post to request a SD1983EVK. I will also notify the responsible engineer to follow-up on this request for SD1983EVK and schematic in Altium format.

    Regards,
    Alan

    Greetings,

    Please below note a link to LMH1983 reference design where you can find schematic in pdf and Altium among other documents:

    Thanks for the follow up. I've requested a dev kit in this thread: e2e.ti.com/.../560009

    It would be great to be able to get one in hand this week. We are finishing schematic work and I would like to verify that the 1983 will fit our timing requirements before we go to layout.

    I encountered the same issue attempting to run the LMH1982 software on Windows 10. Disabling the driver signature enforcement didn't work - I experienced the same crashing behavior.

    Is there another know workaround? If not, and as TI will not support further development of this particular software, would you be willing to post the source code for the software so I can attempt to recompile it for a modern version of Windows?

    Without the working software, I'm stuck with the board in a state that is not useful to my project. And, the LMH1983 board does not appear to support the functionality I need, so swapping it is not a viable path for me.

    Your consideration is greatly appreciated.

    Thanks,
    Scott

    Hi Scott,

    With respect to LMH1983, could you please let me know what functionality you need?

    I've actually solved my problem with the LMH1982 eval kit software. Here's what worked for me. The whole process is free and took less than 15 minutes.

    1. I installed Virtual Box on my Windows 10 computer.
    2. I downloaded the "IE11 on Windows 7" image, which Microsoft makes available for free on their dev site.
    3. I created a new Virtual Machine and added a new empty USB filter so that all USB devices from my host computer would pass through to the Windows 7 virtual computer
    4. I installed the LMH1982 software. The Windows 7 image from Microsoft already contained the prerequisite .NET framework components.
    5. The LMH1982 software worked!

    Specifically, the functionality that I need from the LMH1982 is to take a reference input signal and give me a corresponding TOF signal pulse as an output. However, that's not currently working for me, so I'll open a separate thread now.
