Part Number: TDA2EXEVM Tool/software: TI C/C++ Compiler Hi, How can i implement IPC communication for vision_sdk? i need to implement ipc communication for vision_sdk to receive STOP, RESUME and START command from other modules. I have used the same code ipc_init, ipc_send etc in chains_main.c and included the required header files in the chains.h file. But i am getting an undefined reference error as shown below. --------------------------------------------------------------------------------------- chains_main.c:(.text+0x208): undefined reference to `vDiagPrint' chains_main.c:(.text+0x268): undefined reference to `vDiagPrint' chains_main.c:(.text+0x294): undefined reference to `vDiagPrint' chains_main.c:(.text+0x2ba): undefined reference to `vDiagPrint' chains_main.c:(.text+0x2e6): undefined reference to `vDiagPrint' /home/username/Source/vision_sdk/binaries/tda2ex_mccdvr_all/lib/a15/release/vision_sdk_linux_demo.a(chains_main.o):chains_main.c:(.text+0x33e): more undefined references to `vDiagPrint' follow /home/username/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+0xe): undefined reference to `ipc_init' chains_main.c:(.text.startup+0x88): undefined reference to `vDiagPrint' --------------------------------------------------------------------------------------- can anyone pls help me to to link libraries.?

Responses:
Hi, Ipc Initialization will be automatically done for all core included in the build. You just need to send and received event using IPC. For further implementation info please check how IPC links send informations. Regards, Anuj
