Dear David-san
We took a log to catch when (how long time after application start) reboot occurs.
The logs says around 1100minuite, maybe the raspi got rebooted, no other log.
And the older version and the combination, this phenomena never happened.
libcamera: c3548a333f86d31213ca9f2ccc3faf743b246743
rpi-update: f794477c7c48061a720d6b9331d27f8d0300009c
(We are using the latest one for both.)
Best Regards,
NOMURA

Hello Nomura-san
Thanks for your message.
So we're not aware of any problems like the one you report but we'll see if we can reproduce it - obviously it will take a little while. Do you believe the Pi crashed completely and rebooted? If so, might we be able to get any system logs that could give us a clue as to what happened?
Thanks and best regards
David

Actually it appears to be about 1% below, this is probably because exposure time and analogue gain get slightly quantised because the camera cannot deliver the exact values the AGC algorithm wants.

I forget exactly what the maximum gain is that this sensor supports, but if you ask for larger values you should see the algorithm applying any extra (above what the sensor can deliver) as digital gain. Obviously it will all get noisier and noisier!
