s32v234 not recognized as an internal or external command

Question asked by Willian Campo on Nov 9, 2018

Hello everyone, I have already been able to configure the Matlab environment with the NXP.

But at the time I try to load the program "face_detection_camera_main" to the Board, I get the following error.

"C: \\ Users \\ waclab \\ AppData \\ Roaming \\ MathWorks \\ MATLAB" is not recognized as an internal or external command, program or batch file executable.

I have already tried adding the Path (as shown in the image) but in spite of that it does not work.

If you could help me, it would be very useful.

No one else has this question

Hi Willian Campo,

Can you paste here the MATLAB console output (all of it) please.
I think we have an issue with some white spaces in the path. In general NXP Vision SDK needs to installed in a path without spaces.

Best regards,
Daniel

    Hi Willian Campo,
    I think i know what the problem is.
    There are 2 libstdc++-6.dll files on you PC:
    the default one is loaded from C:\Windows\SysWOW64\libstdc++-6.dll
    the correct one should be loaded from VisionSDK folder
    
    When you install MATLAB this is going to place the libstdc++-6.dll in the “C:\Windows\SysWOW64\” folder and is going to use it as default but this will fail to build the files from the VisionSDK.
    
    For the moment, please go to C:\Windows\SysWOW64\ and rename the libstdc++-6.dll into something else, or delete it.
    After that, the build process of all VisionSDK dependencies should be ok.
    
    Please let me know if its working.
    Best regards,
    Daniel

        Is is possible to be hidden ? Have you configured the explorer to show all files ?
        Try a search please. It might be possible to be in another location.

        Which of them should I modify or eliminate?

        Hi Willian Campo,
        
        The nbuild system from VSDK expects forward slashes / in the paths from these two environment variables. We'll fix this in the next release.
        Can you replace \ with / in APU_TOOLS and S32V234_SDK_ROOT and try again?

        Hi Willian,
        
        I see 2 main issues with your setup.
        First of them: the Vision Toolbox currently available for download supports only VisionSDK 1.1.0
        You have installed the VisionSDK 1.2.0 which can't be used in conjuction with the MATLAB toolbox since they are not compatible. There were changes in 1.2.0 which are no longer compatible with 1.1.0 version.
        The good news is that on November 19, we are going to release the new version of the Toolbox that will be in sync with 1.2.0 VSDK + HF1 + HF2. Can you wait until next week.
        
        Secondly, the APEX compiler is not installed correctly. You should have more files in that folder.
        
        Best regards,
        Daniel

        Hello again,
        I searched for the version VisionSDK_S32V2_RTM_1_1_1, but I could not find it, I only found the version VisionSDK_S32V2xx_RTM_1_0_1_8d46d3.
        But when it comes to the installation, I can not install the NP APU_Compiler_v1.0

        Hi Willian,
        I'm sorry for these inconveniences. Unfortunately we (Vision Toolbox Team) do not control the distribution of VSDK nor APU Compiler. We are just a consumer of their deliveries.
        The link for VSDK 1.1.1 is this one: https://nxp.flexnetoperations.com/control/frse/download?element=10088717
        Please log in into your NXP account then then paste this address into the browser address bar.
        If you are not entitled to see the page, an automatic dialogue report windows will appear that will redirect your query to the technical support. Just comment there that you wish to get access to the VSDK1.1.1 and paste the link below.
        
        Someone from technical support will allocate into your account the VSDK1.1.1 product.
        Hope this will help!
        Daniel

        Now the contents of the folder C: \ NXP \ APU_Compiler_v1.0 \ bin is as follows.

        Hi Willian Campo,
        
        The build system from NXP VSDK doesn't support spaces in paths.
        
        To make it work you need to change the path where the add-ons are installed from the Matlab Preferences window.
        
        Set a path that doesn't contain spaces.

        You could replace "MATLAB Add-Ons" folder with "MATLAB_Add-Ons" (notice the "_" instead of " " character)
        
        It should look something like this: C:\Users\waclab\AppData\Roaming\MathWorks\MATLAB_Add-Ons

        I think we are back to the previous problem with the APU compiler folder instalation empty.
        
        Could you run getenv('APU_TOOLS') in matlab command line?
        And check the content of C:\NXP\APU_Compiler_v1.0\bin folder?

        You have the old version of toolbox installed. Please uninstall it from Matlab and install the latest one, NXP_Vision_Toolbox_S32V234_2018.R1.RFP_20181119.mltbx, from https://community.nxp.com/external-link.jspa?url=http%3A%2F%2Fwww.nxp.com%2Fwebapp%2Fswlicensing%2Fsso%2FdownloadSoftwar…
        
        The ver should show only one NXP_Vision_Toolbox_S32V234_2018.R1.RFP_20181119.mltbx, with version 2.0.0.

        Re-install the toolbox. You have the toolbox previously installed in the path with spaces. After you changes the installation path for add-ons, you need to reinstall the toolbox.
        
        You are very close to build the examples.
