AM62A7-Q1: How can I check the availability of the VPAC without starting a gstreamer pipeline

Part Number: AM62A7-Q1

Tool/software:

Hi,

Using 10.0, I sometimes notice that the VPAC isn't working correctly after boot. If I reboot the board, this usually heals things.

I would like to know how to contact the VPAC components outside of tiovxisp and tiovxldc, so I can verify that the VPAC components are working correctly (by sending a rpmsg to the various co-processors and/or endpoints).

Any help for this would be appreciated.

    Hello Bas,

    There is no such API to let you check or ping VPAC. You probably can write a simple script running a gst pipeline using videotestsrc and tiovxisp. Let the script return error if the pipeline fails.
