Hi Patrick, Thanks for your question and welcome to the PowerVR Developer Forum! Please, when possible try with the latest version of PVRTune, R24.1 (v14.157). You can download it from our Developer Portal ( [Login - Imagination Developers](https://developer.imaginationtech.com/downloads) ). Please note you will need to make a new account to access the downloads section. Let me know if you still have issues after trying with the latest version. Best regards, Alejandro ---

Hi AlejandroC, Thanks for your reply. I downloaded the latest PVRTune for SGX, but it looks does not have a version fits my platform. The platform I am using is Texas Instrument TDA4 VH, with QNX 7.1.0 OS. BR, Patrick ---

Hi Patrick, Thanks for your message. PVRTune v14.157 (R24.1) has binaries for PVRPerfServer QNX v7.1 for Armv8, Armv7 and x86\_64 (folders QNX710\_aarch64le, QNX710\_armle-v7 and QNX710\_x86\_64 respectively inside PVRTune `PVRPerfServer/` installation folder). Your platform (TI TDA4 VH) has Arm Cortex-A72 CPUs, which should be capable of running Armv8 binaries, which corresponds to the ones under the QNX710\_aarch64le folder. Please let me know if I am missing something here and what platform support you would need. Best regards, Alejandro ---

Hi Alejandro I downloaded PVRTune\_for\_SGX.tar from [Login - Imagination Developers](https://developer.imaginationtech.com/downloads/) and extraced, but I do not see QNX folders. It looks like the default version for download is a very old version, can you send me the link for 2024 R1 version as I do not see it on the Dowloads section. BR, Patrick ---

Hi Patrick, Thanks a lot for the clarification. You should try downloading the `Windows` or the `Linux 64-bit` releases, which have the PVRPerfServer QNX 7.1 armv7 / armv8 / x86\_64 binaries: ![image](https://us1.discourse-cdn.com/flex015/uploads/imagination1/original/1X/5bceab00dfc6b16ef550675b91aa7316f9b2d174.png) Best regards, Alejandro ---

Hi Patrick, Thanks a lot for the information, I already reported it to the Tools Team. It would be really useful to know the GPU driver version. It should be in the format `[number].[number]@[number]`, for instance `1.15@6133109` Best regards, Alejandro ---

Hi Alejandro, Thanks for your information. I check the platform and get the rgx firmware version 36.53.104.796 It is not in the format you mentioned, maybe I looked up in the wrong way, please let me know how to get the right GPU driver version. Thanks! BR, Patrick ---

Hi Patrick, If the previous commands do no work, could you please try the alternative options below? - `egl-configs` (QNX tool to output EGL configs & GPU driver version). - command `gles3-gears -verbose` - command `pvrdebug -dds` Let me know if you need any help with this commands.

Hi Patrick, We are able to run the same binaries, with the same GPU driver version, on the same QNX OS version, on a quite similar device (R-Car H3 Starter Kit WS 3.0). We suspect the issue you are experiencing is related with the GPU driver environment / setup. Is there any chance you can do a factory reset of your device and provide any environment details you add afterwards before running PVRPerfServerDeveloper? Best regards, Alejandro ---

Hi Alejandro, Our device is used for self-driving system development, so the enviroment is very complicated. I may not be able to reset it and provide you the details with every single step. If you need any specific enviroment settings, please let me know, and I will try to provide. Thanks! BR, Patrick ---

Hi Patrick, I can think of two options to assist you: - You can generate a backtrace or coredump with gdb, which hopefully will help clarify what is failing. - You can do a clean install of the OS. I am not familiar with the exact device you are working with, but usually they have a memory card / slot where the Operating System is installed. If you can reset that memory card with a clean OS image recommended by Texas Instruments / QNX that would give you a good starting point. There are guides on how to do that, you can also ask TI / QNX for details. After that you could test again whether you are still having the same issues with PVRPerfServer (do not worry about providing environment details) and let me know if that is the case. Best regards, Alejandro ---

Hi Alejandro, Thanks for your advice. I have tried install a clean QNX OS on a EVM board, but it still end up to a coredump. The forum does not allow me to attach a file, so can you please leave a email address for me to send the coredump file? BR, Patrick ---
