Dual capture issue with Xavier AGX and FpdlinkIII

hello andres.artavia,

please start with v4l2 pipeline.
as for now, we got an issue that V4L v.s. Argus were having different timing for waiting deskew signal. the comparison result shows it’s Argus waits for signal too early.
you may test with V4L pipeline to check the stream status. then, it’s able to workaround by configure sensor state as standby (not streaming), then switch the sensor state to stream after you see the RCE deskew setup debug logs.
(i.e. [RCE] Deskew setup message sent for port 0 num_lane 4..)

BTW,
you may see-also Topic 226574 to download JetPack-5.0.2/l4t-r35.1 camera firmware with debug flag enabled.
this debug firmware also helps to dig into the issue, please have this applied to bring-up the camera.
thanks
