[FAQ] PROCESSOR-SDK-DRA8X-TDA4X: OpenVX application hangs with pipelining

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

My OpenVX application is hanging when pipelining with an OpenVX object array when calling vxGraphParameterDequeueDoneRef.  The producer node is a replicated node that is outputting an element of an object array.  There are two consumer nodes, one of which is also a replicated node consuming the element of the object array while the other consumer node consumes the entire object array.  Is there a fix for this issue?

  • This is a known issue in the PSDKRA 7.0 release and the fix will be included within the PSDKRA 7.1 release.  In the meantime, a patch has been included on this post to fix this issue.  This patch can be applied within the tiovx directory.  The tiovx framework must then be rebuilt by running "make tiovx" from the vision_apps directory, then the application can be rebuilt for this fix to take effect.
