[Elphel-support] No images from sensor

[Linden Mills-Connery]

I am not sure what triggered the issue as I was not operating the camera.
But yes I change several parameters between getting the camera set-up and
putting it in line-scan (recording) mode. I am curious what would be
the recommended way of changing parameters with HTTP requests. Currently I
am emulating the HTTP request made by autocampars.php to change parameters.

Output of that call:
[root at Elphel353 /usr/html]788# php autocampars.php --init
X-Powered-By: PHP/5.2.9
Content-type: text/html

Is this as simple as re-flashing the original  /etc/autocampars.xml file?

Thanks,
