Linux/TDA2: TDA2 - 'Undefined reference Error'

Blessy Abraham

Part Number: TDA2


Tool/software: Linux

Hi,

I am working with VisionSDK 3.1.

I am trying to add a new usecase in vision_sdk/apps/src/hlos/adas/src/usecases. The main function that I have used is Void chains_lvdsVipMultiCam_opencvcanny_SgxDisplay(Chains_Ctrl *chainsCfg) which is defined in the corresponding usecase .c file. This function was called in vision_sdk/apps/src/hlos/adas/src/common/chains_main.c which includes a header #include <src/hlos/adas/include/chains.h>. The function was declared in the above mentioned header.

While compiling I am getting the following error.

# apps: tda2xx-evm: Creating archive apps.a

How can I solve this.

    Hi Blessy,
    Better to use tda2xx_evm_linux_opencx config while building OpenCV applications
    Ensure your new use-case added to uc_cfg.mk file & to LINUX_TDA2XX_UC_LIST under vision_sdk\apps\configs\cfg.mk file

    Hi Surya,

    I tried compiling with tda2xx_evm_linux_opencx. I am still facing the same issue. Infact the number of errors increased. Usecase is defined in cfg.mk and uc_cfg.mk

    Hi Blessy,
    You need to add "chains_lvdsVipMultiCam_opencvcanny_SgxDisplay" to MAKEFILE_adas.MK file under vision_sdk/apps/src/hlos
    All algorthim link init plugins are under #ifdef in algorithmLink_cfg.c file
    Could you share your cfg.mk file in use-case folder (need to check which all ALG enabled) ?

    Regards

    Hi Surya,

    The new use-case i have added is "lvds_vip_multi_cam_opencvcanny_sgx_display". I have included this use-case in MAKEFILE_adas.MK as

    ifeq ($(UC_lvds_vip_multi_cam_opencvcanny_sgx_display),yes)

           $(MAKE) -fMAKEFILE.MK -C$($(MAKEAPPNAME)_PATH)/src/hlos/adas/src/usecases/lvds_vip_multi_cam_opencvcanny_sgx_display MODNAME=$(MAKEAPPNAME) CORE=a15_0 $(TARGET)

    endif

    I am not able to attach the cfg. mk file. Below are the contents of cfg.mk

    ALG_dmaSwMs=yes
    ALG_opencvcanny=yes
    NEED_PROC_IPU1_0=yes
    NEED_PROC_A15_0=yes

    Hi,

    1st make sure your build system is not broken.
    Try a clean build without adding the new usecase.

    I hope after changing any cfg file you are doing a clean build.
    Please share the output of make showconfig.

    Is the issue resolved?
    If yes, then please close the thread as there is no activity since a long time.
