Hello.
I am working on creating a new OpenCV algorithm that works on the A15 core.
First, I built app with the OpenCV Canny algorithm and NullSrc Usecase.
However, OpenCV does not work in Usecase.
The link structure of UC is as follows.
NullSrc (A15) -> Decode -> VPE -> Alg_OpenCVCanny (A15) -> Sgx_Frmcpy (A15) -> Display
The setting of UC was the same with NullSrcDecDisplay and vip_single_cam_opencvcanny_sgx_display UC.
The process of running UC is as follows.
1. cd / opt / vision_sdk
2. source ./vision_sdk_load.sh
3. ./app.out
Here are part of my log messages:
