Responses:
Hi What is the vision SDK version you use? Which OS on A15, Linux or Bios? regards, Shiju

visionsdk version is 3.3 , run linux on A15

I could see a lot of undefined reference to some symbols, i guess these are from your new Algorithms, Please include the Alg lib in \vision_sdk\apps\MAKEFILE.MK See how other OPENVX_A15_LIBS are included as reference Another option is to compile your files along with Alg plug-in files regards, Shiju
