Linux/DRA746: About OpenCV Issue

Part Number: DRA746
Other Parts Discussed in Thread: TVP5158,

Tool/software: Linux

Hi Sir 

we download latest automotive processor sdk from TI and do opencv test. the system showed error message as below 

root@dra7xx-evm:~# ./opencv_test 

TIOCL FATAL: OpenCL needs 1 CMEM blocks to operate - one each for off-chip (DDR) and on-chip (MSMC SRAM or OCMC RAM) memory.

Q1: Does TI have any suggestion to fix this issue ?

Q2: Where can we geit OpenCV sample code ? or we need to download via  the yocto pacakge ?

thanks 

BR

    Hi Yimin,

    there is a patch that needs to be applied and firmware to be loaded for OpenCL to work, please check this steps:
    processors.wiki.ti.com/index.php

    Then you can test OpenCV as described here:
    processors.wiki.ti.com/index.php

    Hi Yimin,

    I am not sure about this error. I have pinged OpenCL experts to help.

    Hi Yimin,

    You mentioned DRA746 in your ticket, could you also confirm below

    - Release: Is it PSDKLA 3.04.00.03?
    - What dts are you using in your setup
    - Are you using the prebuilt binaries or built the images

    Aside the error messages, were you able to run the OpenCL kernels at all?

    Thanks,
    Gowtham

    Hi Sir

    the reply is below 

    - Release: Is it PSDKLA 3.04.00.03?

       Yes


    - What dts are you using in your setup

          please refer to attachment 

        https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/1602.dts.7z

    - Are you using the prebuilt binaries or built the images

        Yes. I am using the prebuilt filesystem and kernel. Besides, I also patch the .dtb file to the target board /boot folder manually.

    - were you able to run the OpenCL kernels at all?   

        The below is the configuration and messages for your reference. As you can see, I had linked the xe66 fw to opencl-monitor.

    Hi Yimin,

    I believe you have the OpenCL kernels working as expected. The other messages are not affecting the execution of the kernels itself. Please raise a separate ticket for the occurrence of `omap_hwmod:mmu_....` messages.

    Thanks,
    Gowtham
