Ticket Name: RTOS/TDA2: Adding new usecase and get compiling error “unresolved symbols remain”

Query Text:
Part Number: TDA2 Tool/software: TI-RTOS Hello，I'm trying to add new usecase to VSDK, and when I compiled it, I got the error "unresolved symbols remain". Below is the log: ================================================================ # Making tda2xx-evm:ipu1_0:release:vision_sdk_lib... # Linking into D:/PROCESSOR_SDK_VISION_03_05_00_00/vision_sdk/binaries/apps/tda2xx_evm_bios_all/vision_sdk/bin/tda2xx-evm/vision_sdk_ipu1_0_release.xem4... # undefined first referenced symbol in file --------- ---------------- Chains_lyratidlOD D:/PROCESSOR_SDK_VISION_03_05_00_00/vision_sdk/binaries/apps/tda2xx_evm_bios_all/lib/tda2xx-evm/ipu1_0/release/app_libs.aem4<chains_main_bios_tidl.oem4> error: unresolved symbols remain error: errors encountered during linking; "D:/PROCESSOR_SDK_VISION_03_05_00_00/vision_sdk/binaries/apps/tda2xx_evm_bio s_all/vision_sdk/bin/tda2xx-evm/vision_sdk_ipu1_0_release.xem4" not built gmake[7]: *** [D:/PROCESSOR_SDK_VISION_03_05_00_00/vision_sdk/binaries/apps/tda2xx_evm_bios_all/vision_sdk/bin/tda2xx-evm/vision_sdk_ipu1_0_release.xem4] Error1 gmake[6]: *** [ipu1_0] Error 2 gmake[5]: *** [apps_ipu1_0] Error 2 gmake[4]: *** [apps] Error 2 gmake[3]: *** [apps] Error 2 gmake[2]: *** [apps_exe] Error 2 gmake[1]: *** [apps] Error 2 gmake: *** [vision_sdk] Error 2 ================================================================ Below is what I have done: 1. I prepared all the file according the usecasegen document 2. Add the usecase to uc_cfg.mk under vision_sdk/apps/configs/tda2xx_evm_bios_all, 3. Add the usecase to cfg.mk under vision_sdk/apps/configs/cfg.mk 4. in vision_sdk/apps/Makefile, I add: -include $(MODULE_SRC_BASE_PATH)/rtos/usecases/lyra_tidl_OD/SRC_FILES.MK Then I removed the binaries directory and do gmake -s -j depend, then gmake -s -j, and then I get the error I described previously. Did I do anything wrong here? I also run the command gmake -s showconfig and I did see my usecase was built. The last one UC_lyra_tidl_OD is the usecase I added.

Responses:
Hi, Seems like you are calling Chains_lyratidlOD function from apps/src/rtos/common/chains_main_bios_tidl.c file. But have you defined your usecase entry function with the same name Chains_lyratidlOD. Please add some error in your usecase file to confirm that these are getting build. Regards, Anuj

Hello Anuj， the problem is solved~ thanks for your reply.
