TDA2EG: How to use OpenCV features on TDA2Ex?

Part Number: TDA2EG

Hi 

   I am studying how to use OpenCV features on TDA2Ex board.

   First, i compiled the SDK with the configuration "tda2xx_evm_bios_opencx", and it finished with no errors.

   Then, i want to append OpenCV on configuration  "tda2ex_evm_bios_all", as my board is based on TDA2Ex.

   According to "tda2xx_evm_bios_opencx", i changed the configuration files of "tda2ex_evm_bios_all" as folow:

   \vision_sdk\apps\configs\tda2ex_evm_bios_all\cfg.mk: (append following codes)

   OPENCV_OPENCL=yes

   OPENCL_INCLUDE=yes

   ENABLE_OPENCV=yes
   ENABLE_OPENCV_TESTS=yes
   BUILD_OPENCV_SRC=no
   TREAT_WARNINGS_AS_ERROR = no

   \vision_sdk\apps\configs\tda2ex_evm_bios_all\uc_cfg.mk: (append following codes)

ifeq ($(ENABLE_OPENCV),yes)
UC_vip_single_cam_opencvcanny=yes
UC_vip_single_cam_opencvopencldilation=yes
ifeq ($(ENABLE_OPENCV_TESTS),yes)
UC_vip_single_cam_opencvtests=yes
endif
endif

   But the compiling failed with the following errors:

    when i comment the rtos_init_ocl_dsp_monitor call at vision_sdk\links_fw\src\rtos\links_common\system\system_common.c, the undefined symbol error above is not exist.

    But other link errors happen when creating the image of A15:

    It seems that BIOS/Pthread and OpenCL related libraries are not linked into the final A15 image, so above errors were happen.

    So please tell me how to solve above problems, thank you~

    Thanks

    Hello
    Are you trying to build and run the excising VSDK OpenCL UC or planing to add your-own OpenCL functions/features?

    Hi

       yes, i want to add my own opencv features on rtos 2D SRV usecase.

    Thanks

    Hi Xuanbo,
    Apart from changes made to enable openCV on tda2ex-evm, few more changes required
    grep for "OPENCL_INCLUDE" & "ENABLE_OPENCV" flag in vision_sdk folder
    You need to port changes in cfg files & memsegment.xs file changes of tda2xx to tda2ex
