Ticket Name: Linux/TDA2: TDA2xx\linux build my own usecase

Query Text:
Part Number: TDA2 Tool/software: Linux i am a newer to learn TI\TDA2xx ， i have write a new usecase ，the config file is： UseCase: chains_newTestDisplay NullSource (A15) -> Decode -> Alg_FrameCopy (A15) -> VPE -> Display and i refer to the example of chains_nullSrc_Display.c to write my chains_newTestDisplay.c file typedef struct { UInt32 NullSourceLinkID; UInt32 IPCOut_A15_0_IPU1_0_0LinkID; UInt32 IPCIn_IPU1_0_A15_0_0LinkID; UInt32 DecodeLinkID; UInt32 IPCOut_IPU1_0_A15_0_0LinkID; UInt32 IPCIn_A15_0_IPU1_0_0LinkID; UInt32 Alg_FrameCopyLinkID; UInt32 IPCOut_A15_0_IPU1_0_1LinkID; UInt32 IPCIn_IPU1_0_A15_0_1LinkID; UInt32 VPELinkID; UInt32 DisplayLinkID; NullSrcLink_CreateParams NullSourcePrm; IpcLink_CreateParams IPCOut_A15_0_IPU1_0_0Prm; IpcLink_CreateParams IPCIn_IPU1_0_A15_0_0Prm; DecLink_CreateParams DecodePrm; IpcLink_CreateParams IPCOut_IPU1_0_A15_0_0Prm; IpcLink_CreateParams IPCIn_A15_0_IPU1_0_0Prm; AlgorithmLink_FrameCopyCreateParams Alg_FrameCopyPrm; IpcLink_CreateParams IPCOut_A15_0_IPU1_0_1Prm; IpcLink_CreateParams IPCIn_IPU1_0_A15_0_1Prm; VpeLink_CreateParams VPEPrm; DisplayLink_CreateParams DisplayPrm; } chains_newTestDisplayObj; But when i run my usecase on the HW environment，it crashed ，the info is： [HOST] [HOST ] 806.707100 s: IPC_OUT_0 : Create in progress !!! [HOST] [HOST ] 806.707161 s: IPC_OUT_0 : Create Done !!! [HOST] [IPU2 ] 806.707344 s: IPC_IN_0 : Create in progress !!! [HOST] [IPU2 ] 806.708534 s: IPC_IN_0 : Create Done !!!

[HOST] [IPU2 ] 806.934697 s: DECODE: Creating CH0 of 1280 x 720 [1] [0],target bitrate = 10000 Kbps ... I want to know the rules and more details of how to write the file of chains_nullSrc_Display.c，Is I missing some functions in chains_nullSrc_Display.c？ when i change my ALG（Alg_FrameCopy），How to modify my file of chains_nullSrc_Display.c？ Looking forward to answering me，thank you very much！

Hi , Please refer the frame copy usecase and set the required framecopy alg id in usecase. vision_sdk\apps\src\rtos\usecases\vip_single_cam_frame_copy Regards Chetan.M
