you can read the source code to understand how it works.
To get the source code, you can type this command.
./ltib -p imx-test -m prep
then the source code will be extracted in the folder : ltib/rpm/BUILD/imx-test-3.0.35/
you can modify the source code and then build it again. To re-build it, please type
./ltib -p imx-test -m scbuild
Then install it to rootfs again.
./ltib -p imx-test -m scdeploy
For more information, please download the BSP documentation
There is i.MX_6Dual6Quad_VPU_API_Reference_Manual.pdf, in section 4.4.2 VPU Example Application talk about the VPU test in details.
