<![CDATA[MV-MIPI-SC130M autoexposure problem]]>Hi,
I am using MV-MIPI-SC130M camera with RK3588S basic image from VEYE.
Camera is configured used to hardware trigger mode on rising edge, aemaxexposure time is 5000 mks.
Sometimes after restarts autoexposure mode does not work, current exposure time is near 4600 - 4800 ms and does not changes, even if I change aemaxexposure value.
After restart autoexposure works normally.

We use regular external trigger, target framerate is 20 fps. Ambient lighting not stable, so we have to use autoexposure mode.

Generally, in external trigger mode, manual exposure is recommended.
This is because the algorithm of the automatic exposure mode relies on regular image input, whereas the trigger intervals in external trigger mode may be random or even very long.
If the ambient lighting in your application scenario is stable, it is still advisable to use manual exposure mode.
