hello whn,
please refer to developer guide, you may check SerDes Pixel Clock session for details.
re-cap as below.
Skew calibration is required if sensor or deserializer is using DPHY, and the output data rate is > 1.5Gbps.
hence,
deskew calibration is a must if data-rate > 1.5 Gbps, Else the camera firmware will continue to wait for deskew signal from the sensor side. it’ll enable pixel parser when deskew calibration has completed.
FYI,
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. (we’re trying to resolve this internally)
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),
here’s camera firmware with debug flag enabled in order to obtain more details, i.e. Topic 226574.
it’s based-on JetPack-5.0.2/l4t-r35.1, however, it still works on JP-5.1 for debug purpose.
