Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: MMWCAS-DSP-EVM

Tool/software:

Hi TI Team,

I am trying to use mmwcas-rf-evm and mmwcas-dsp-evm with mmWave Studio, but I keep getting the following error:

Exception message is:  
Unable to find an entry point named 'RadarLinkImpl_setSystemType' in DLL 'RadarLinkDLL.dll'.

Here is what I have already tried:

  • Tested with mmWave Studio 2.1.1.0 (latest release) and also 3.0.0.14.

  • Tried on two different Windows 11 laptops.

  • Installed the correct MATLAB Runtime 8.5.1 (32-bit). (see attached screenshot)

  • Verified that Microsoft Visual C++ 2013 Redistributables (x64 and x86, version 12.0.40660) are installed (see attached screenshot).

  • FTDI drivers were installed correctly during mmWave Studio setup at: C:\ti\mmwave_studio_02_01_01_00\ftdi (see attached screenshot)

  • Attaching screenshots of my device manager 

  • Verified that RadarLinkDLL.dll is present in both the RunTime folder and Clients/AR1xController folder.

  • Also tried uninstalling, deleting all files, and reinstalling from scratch.

Unfortunately, the same error persists in all cases.

Can you please guide me on what could be wrong?

Thanks in advance for your help.

(Attached screenshots of the error, redistributables installed, and FTDI driver info.)

    Hello,

    Please see similar thread. Unfortunately, it is extremely difficult for us to pinpoint why you are seeing this error as it is PC dependent.

    Hi Adrian, 

    I see that this issue has been reported by quite a few people, and the solution does not appear to be conclusive. I have gone through the queries in the link you shared, and different users have resolved it using different approaches. One of the suggestions mentions an XDS emulation software, but your manual does not mention this anywhere. Could you please clarify what this software is, where I can download it from, and whether it could help resolve my error?

    Also, I had installed mmWave Studio in admin mode while the hardware was connected. The installation wizard showed the FTDI drivers being successfully installed (refer to the above screenshots), and I can also see them under the FTDI folder (screenshot attached). Could you please check my Device Manager screenshot and let me know if this looks like a driver issue?

    Finally, can you confirm whether the current version of mmWave Studio is fully compatible with my hardware or not?

    Thanks in advance for your support.

    My DLL issue is resolved and I just wanted to post here for public information - 

    It turned out that the issue was not related to the DLL or FTDI driver. The problem was with the Microsoft Visual C++ Redistributable Packages version mentioned in the manual.

    The manual listed the 2013 package, but that alone did not solve the issue. I had to install multiple versions of the redistributable packages. Specifically, I downloaded and installed the following x86 versions:

    • Microsoft Visual C++ 2012 Redistributable

    • Microsoft Visual C++ 2013 Redistributable

    • Microsoft Visual C++ 2015–2022 Redistributable

    After installing these, the software finally worked. I cannot pinpoint whether a single package fixed the issue or if it required the combination of 2012, 2013, and 2015–2022.
