[Elphel-support] Camera Issues

[Andrey Filippov]

Diana,

until the recent bug fix I mentioned in one of the previous posts, the
camera without the sensor would  not complete the startup sequence with
autocampars.php getting stuck trying to initialize the non-existent sensor.
In that condition ping, telnet would work, but not the web server.  USB,
time synchronization would also be never reached.

With that bug fixed, the autocampars.php continues, and the web server is
initialized as well as the USB and other services, boot up sequence will be
finished properly. But sure enough nothing that requires sensor operation
will work, any PHP script that depends on incoming camera frames will get
"frozen".
