Part Number: TDA2PXEVM Hi, Recently I started working with PSDK Vision. I am trying out my own usecase. This is my usecase, But the output which i see in the console after doing make is, [HOST] [HOST ] ========================================= [HOST] [HOST ] Chains Run-time Codec Type Selection Menu [HOST] [HOST ] ========================================= [HOST] [HOST ] [HOST] [HOST ] Enter '0' for MJPEG [HOST] [HOST ] [HOST] [HOST ] Enter '1' for H.264 [HOST] [HOST ] [HOST] [HOST ] Enter Choice: [HOST] [HOST ] 1 [HOST] [HOST ] 58.511071 s: IPC_OUT_0 : Create in progress !!!

Responses:
Hi Sam, Do you have "ALG_edgedetection=yes" in "cfg.mk" of your usecase? Also can you make sure "AlgorithmLink_EdgeDetection_initPlugin()" is called in "App_init()" in vision_sdk/apps/src/common/app_init/app_init_eve.c. You can check this post (it is for adding a new alg plugin, but you can use it as a reference to check if a particular plugin is initialized by the usecase): You can also look at existing vision_sdk/apps/src/rtos/usecases/vip_single_cam_edge_detection usecase as a reference as it is quite similar to your one. Regards, Yordan

Hi Yordan, I took help from the usecase mentioned above. Content of cfg.mk ALG_edgedetection=yes NEED_PROC_IPU1_0=yes NEED_PROC_A15_0=yes NEED_PROC_EVE1=yes In app_init_eve.c's App_init() function, #ifdef ALG_edgedetection AlgorithmLink_EdgeDetection_initPlugin(); #endif I searched all files i can, but everything seems OK to me.

Hi 1)Please share output of the below command "make showconfig" 2)are you creating usecase using auto-gene-usecase tool ? or manually? 3) Add print statement inside the following function & check this print is coming or not when you run apps.out. AlgorithmLink_EdgeDetection_initPlugin(); Thanks Gaviraju
