Dear all,
we have a bunch of 353-based stereo cameras that are in operation for
seven years meanwhile and we've been very happy with them. Over the last
weeks, some of them have image errors, at first sight it looks like one
of the sensor is not configured correctly, a combined image looks like:
I found that this seems to be a problem with the 10359 multiplexer board
-- exchanging this resolves the issue for a camera.
When booting, the relevant portion of dmesg reports this error on the
affected cameras:

I have tried to set the clock parameters from a functioning specimen via
the /359/10359_controls.html which temporarily resolves the issue, but
after a reboot the problems reappear.
Any chance to resolve this in software or do we need to exchange boards?
If so - are they still available?
All the best from Austria, stay healthy,
Simon
