PXP testing

Hi all,

We've had an ongoing discussion on the meta-freescale list about how to test the Pixel Pipeline (PXP) device.
https://lists.yoctoproject.org/pipermail/meta-freescale/2015-April/thread.html#13349

In short, it appears that the unit_test program for the PXP is broken and not well documented, though the
gstreamer-1.0 pxp elements are partially functional.

Carlos used the gstreamer elements to perform a very thorough test of all pixel formats that are advertised by the driver:

It appears that support for many are broken.

Please join the conversation if you have knowledge in this area.

Hi James,

Otavio is the one who pointed out that we weren't including PXP in our device tree!

I did forward the community thread on and waiting for a reply from the team that owns PXP.

PXP (includdng unit test cases) will have updates in next release but not sure if that addresses this issue you reported.

I tested PXP unit-test with the latest imx7D release and I faced exactly the same error.
