How to use OpenVX extension example

Hello NXP Community,

Inline with Weilly's above request, I also want to build an OpenVX application using Gaussian filter example for i.MX8QuadMax

Available information at link1, link2, and link3 provide detail insight about OpenVX, however, none of them talks about the procedure to build the OpenVX application. I would appreciate if someone can point me to the correct resource to build the OpenVX application for i.MX8QuadMax.

Thank you.

Shiva

Dear, Shiva

this DEMO had run successfully on i.mx8qm/imx8mp.
You can follow the step on Linux:
1. set up i.mx8qm environment
$ source /opt/fsl-imx-xwayland/5.4-zeus/environment-setup-aarch64-poky-linux
2. Enter Folder
cd gaussian_filter
3. Compile Code
make
4. Copy Shared Library file to i.MX8QM
scp gaussian root@xx.xx.xx.xx:~
5. Run on i.MX8QM
./gaussian

But NPU Performance Can't Display on the DEMO...
Maybe Modify OPENVX Code... can do it !!
