Query Text:
Part Number: TDA2EXEVM Tool/software: Linux Hi there, I am using vision sdk version 2.12. I am trying to add a new usecase in vision_sdk/hlos/examples/adas/src/usecase. The main function that I have used is Void chains_multichannel_analog_dvr(Chains_Ctrl *chainsCfg); which is defined in the corresponding usecase .c file. This function was called in vision_sdk//hlos/examples/adas/src/common/chains_main.c which includes a header #include <vision_sdk/hlos/examples/adas//include/chains.h>. The function was declared in the above mentioned header. While compiling I am getting the following error.(earlier there some use-cases which are working fine) ----------------------------------------------------------------------------------------------------------- # vision_sdk_linux_demo: tda2ex-evm: Compiling chains_multichannel.c # vision_sdk_linux_demo: tda2ex-evm: Compiling chains_multichannel_priv.c # vision_sdk_linux_demo: tda2ex-evm: Compiling defLinkMultich_tsk.c # vision_sdk_linux_demo: tda2ex-evm: Creating archive vision_sdk_linux_demo.a # vision_sdk_linux_demo: tda2ex-evm: Linking /home/madan/McCDVR/mccdvr/Source/vision_sdk/binaries/tda2ex_mccdvr_all/lib/a15/release/vision_sdk_linux_demo.a(chains_main.o): In function `main': chains_main.c:(.text.startup+0x3e): undefined reference to `chains_multichannel_analog_dvr' collect2: error: ld returned 1 exit status make[4]: *** [exe] Error 1 make[3]: *** [apps] Error 2 make[2]: *** [demo] Error 2 make[1]: *** [vision_sdk_linux] Error 2 make: *** [vision_sdk_linux_all] Error 2 ------------------------------------------------------------------------------------------------------------ to be informed, i have included the new use-case in the following files, in configs/cfg.mk LINUX_TDA2XX_UC_LIST = \ /*some more use-case inclusions*/ UC_vip_2CH_vdec_encode \ UC_multichannel_Analog \ in system_cfg.h #define UC_vip_2CH_vdec_encode_no #define UC_multichannel_Analog in uc_cfg.mk UC_vip_4CH_vdec_display=no UC_multichannel_Analog=yes and in MAKEFILE_adas.MK ifeq ($(UC_multichannel_Analog),yes) $(MAKE) -fMAKEFILE.MK -C$(vision_sdk_PATH)/hlos/examples/adas/src/usecases/multichannel_Analog MODULE=vision_sdk_linux_demo $(TARGET) endif and also have checked make make showconfig ans i have the below information. # Use-cases included in build, # UC_cabin_channel_dvr UC_front_channel_dvr UC_McCDVR_TriChannel UC_multichannel_Analog # How can i solve this.

Hi Balaji, Lets Check with an existing UC where all it has been added & you need to do similar changes for newly added UC 1. Run grep command for an existing UC folder, check where all it has been added grep -ri "vip_single_cam_sgx_display" from vision_sdk folder 2. Run grep command for an existing UC entry function name present in .c file & check where all it has been added grep -ri "chains_vipSingleCam_SgxDisplay" from vision_sdk folder 3. In similar places, you need to add your newly added UC 4. After adding in all places just do a clean build Regards Surya

Hi Surya, Hope you are doing well. My issue got resolved, in uc_cfg.mk UC_vip_4CH_vdec_display=no UC_multichannel_Analog=yes(space)- i had given this extra space. Thank you Regards Balaji T
