Hello

Im trying to use opencv with linux on TDA2xx SoC, vision version 03.04.00.
Building the kernel and running it, is working fine but when i try to build SDK i get the following error:

# Making tda2xx-evm:c66xdsp_1:release:vision_sdk_lib...

________________________________________

I do not get this when i build SDK for (normal) linux without opencx.

I tried to figure out where are those functions, and it seems they are both in
ti_components/codecs/framework_components_3_40_02_07/packages/ti/sdo/fc/edma3/edma3_config.c
and
ti_components/codecs/codec_engine_3_24_00_08/cetools/packages/ti/sdo/fc/edma3/edma3_config.c

I also tried to change mkefiles so build would pass but with no success.

I followed the Linux User Guide pdf and should have setup both Codec Engine and Framework Components correctly.

Thanks for reading this and for help in advance!

    Hi,

    can you try to delete directory "vision_sdk/binaries/$(MAKEAPPNAME)/$(MAKECONFIG)" and then run "make -s depend" and "make -s" (sometimes -j option causes such errors) and see if you get the error?

    Regards,
    Yordan

    Hi Yordan, thank you for responding,

    I have tried what you said and it did not help, how ever i came to conclusion that edma3_config.c files dont even get compiled.
    I placed intentional errors in those .c files and make return no errors for them, everything runs the same.

    Is it possible that make files dont have correct paths? Im running out of ideas.

    Hi,
    Could you make sure dsp compiler bin path added to PATH variable ?
    If not please run below command
    export PATH=<path_to_dsp_compiler_8.1.0>/bin:$PATH
    & then build

    Regards

    Yes dsp compiler is installed and path is exported.
    I have removed every opencl build for dps, edited some make files so opencvCannyLink_priv and iOpenCVCannyAlgo could be compiled and now i have this error:

    Hi
    OpenCL uses prebuilt dsp binaries which is part of OpenCL file system patch
    Could you please confirm OpenCL file system patch extracted in targetfs folder ?
    Also please run "ls -al" in ti_components\cg_tools\linux & share ?

    Hi
    I got the issue, while building VSDK pass target as "opencx"
    make -s -j depend
    make -s -j opencx

    Hi,
    Even though you extracted opencl_fs_patches.tar.gz in targetfs folder, the content of the tar ball is not copied to respective folder (lib/ & usr/ folder)
    you can cross check this by navigating to below folder
    ti_components/os_tools/linux/targetfs/usr/share/ti -> are you able to see "opencl" folder ?

    If not,Please manually copy the folders using below commands from "ti_components/os_tools/linux/targetfs" folder
    cp -r opencl_fs_patches/lib .
    cp -r opencl_fs_patches/usr .
    & then build

    Hi Surya
    Sorry if im posting multiple and same answers, im being filtered by forum moderator and im not sure how that exactly works.

    I cleared my previous build and tried running

    make -s -j opencx
    and now problem looks like this:

    Hi
    Looks like cfg.mk file has been modified
    & also I am not able to find out the value set for BUILD_OPENCV_SRC
    Could you please share the cfg.mk file for tda2xx_evm_linux_opencx

    Hi

    Yes i have modified cfg.mk file for tda2xx_evm_linux_opencx build.
    When i run make -s -j depend it gives me warning that i need to add ipu1_0 and dsp1 cores to build.

    cfg file:

    #
    # This file defines the modules included in $(MAKECONFIG) config
    #
    # Modules are split into,
    # - Use-cases specified in uc_cfg.mk
    # - Other system config/feature, specified in this file
    #
    # Any specific overrides are also specified in this file
    # Example, for TDA3x SoC EVE2/3/4 are not present and hence force marked as <blank>, i.e disabled
    #

    #
    # Additional config options
    #

    #

    Hi,
    You can ignore those warnings & disable those cores
    In case of Linux ipu2 is only required as it is the primary core
    & OpenCL uses prebuilt dsp firmwares

    And I observed you enabled BUILD_OPENCV_SRC=yes
    Did you intend to build openCV source ?
    Did you clone the OpenCV source repo before building?

    The below issue reported by you while running make opencx is because of BUILD_OPENCV_SRC=yes
    e2e.ti.com/.../2693282

    You can set BUILD_OPENCV_SRC=no & run command make opencx

    Regards
    Surya

    Hi

    I did not clone opnencv repo, where can i refer to setting up opencv source?
    I must have overlooked that part in VisionSDK_UserGuide_opencx.pdf if its there.

    Also im nearly 100% positive i did not touch BUILD_OPENCV_SRC flag, ok ill set it to no and try again.

    Ill get back to you as soon as i try that, thanks.

    Hi, again

    The guide for opencv states this:

    This repository can be cloned with the below command
    git clone git://git.ti.com/opencv/tiopencv.git
    In order to build opencv source as part of vision sdk build, follow the below
    procedures
    * Navigate to ‘ti_components’ folder
    * Then, navigate to ‘algorithms_codecs’
    * Now, clone the ‘tiopencv’ repo using the above mentioned command
    * Set the env variable, ‘BUIILD_OPENCV_SRC’ to ‘yes’ in the ‘tda2xx_evm_<OS>_opencx’ config

    Now my ti_components dir looks like this:

    [~/PROCESSOR_SDK_VISION_03_04_00_00/ti_components]$ ll
    total 36
    drwxrwxr-x 18 rtrk rtrk 4096 сеп 7 14:38 algorithms
    drwxrwxr-x 3 rtrk rtrk 4096 сеп 7 14:38 ccs_csp
    drwxrwxr-x 3 rtrk rtrk 4096 сеп 7 14:39 cg_tools
    drwxrwxr-x 11 rtrk rtrk 4096 сеп 10 09:44 codecs
    drwxrwxr-x 4 rtrk rtrk 4096 сеп 7 14:38 drivers
    drwxrwxr-x 5 rtrk rtrk 4096 сеп 7 14:39 networking
    drwxrwxr-x 5 rtrk rtrk 4096 сеп 7 14:39 open_compute
    drwxrwxr-x 5 rtrk rtrk 4096 сеп 7 14:39 os_tools
    drwxrwxr-x 3 rtrk rtrk 4096 сеп 7 14:39 radar

    I dont have algorithms_codecs dir, should i make one and proceed or use existing algorithm or codecs dirs?

    Also there it states that i should set BUILD_OPENCV_SRC=yes, and i noticed this:
    tools_path.mk:145:OpenCV_BUILD_PATH ?= build_dummy
    is this ok, or should i change OpenCV_BUILD_PATH to correct path?

    What should i do?

    Hi 

    You can clone under open_compute dir, We will update the document in upcoming release

    Set BUILD_OPENCV_SRC to "yes", if you intend to build opencv src & to "No", if you want to use prebuilt

    No need to change anything in tools_path.mk file "OpenCV_BUILD_PATH ?= build_dummy" as when you build for either BIOS or Linux config, it will be overwritten accordingly

    To verify whether you able to build opencx on Linux,

    set BUILD_OPENCV_SRC = no, so that it will use the prebuilts

    Also ipu1_0 & dsp1 to no & then try a clean build

    Regards

    Hi
    Everything looks fine
    I briefed the steps followed by me which is working fine for me, Could you please try at your end ?

    1. Ensure kernel/u-boot/sgx/cmem all are cloned & are on vsdk 3.4 release tag
    2. Ensure file system downloaded from the link provided in vsdk 3.4 Linux user guide & untarred in targetfs folder
    3. Ensure Opencl file system patch applied on file system
    4. Ensure dsp tool chain ti-cgt-c6000_8.1.0 downloaded & installed in ti_components/cg_tools/linux folder
    5. cd vision_sdk/build
    6. Modify MAKECONFIG=tda2xx_evm_linux_opencx in Rules.mk file
    7. export PATH= <path to ti-cgt-c6000_8.1.0/bin>:$PATH
    8. make clean
    9. make linux_clean
    10. make linux
    11. make linux_install
    12. make -s -j depend

    Hi Surya

    I did clean install of vision 3.04 and everything as you listed, now i dont have any dsp errors but undefined main symbol error remains.

    Im using ubuntu 16.04 and not 14.04, could that cause any errors?

    Hi Surya

    Link from where i downloaded dsp dgt:
    www.ti.com/.../8.1.0

    "Also could you please download dsp tool chain (ti-cgt-c6000_8.1.0) one more time & try building ?"
    I did that multiple times before, same results.

    I have now moved to work with rules for MAKECONFIG?=tda2xx_evm_linux_all
    where i have set flags to include openCL and openCV to build.

    That passes with no major problems, but now when i login to system on TDA2x platform and when i try to test openCL this is what i get:

    root@dra7xx-evm:/usr/share/ti/examples/opencl/vecadd# ./vecadd
    CMEM Error: init: Failed to open /dev/cmem: 'No such file or directory'
    TIOCL FATAL: The cmemk kernel module is not installed. Consult the OpenCL UserGuide at software-dl.ti.com/.../index.html

    I did install cmem in ~/PROCESSOR_SDK_VISION_03_04_00_00/ti_components/os_tools/linux/kernel/cmem, and apply opencl_fs_patches.tar.gz
    Have i missed some steps for correctly making cmem?

    Hi
    After login as root
    did you run "load_ocl_kos.sh" under "/opt/vision_sdk" dir or not ?
    This is required to initialize CMEM

    Hello Surya, i dont know why am i getting notification for your reply just now.

    We have found existing issue in vision release note:
    ADASVISION-1894 [TDA2xx Linux] OpenCL UC, Cmem initialization fails.

    So we have paused that part of project until that gets fixed.
