[Elphel-support] how to dump code into camera

[gaurav dasondhi]

Dear oleg
               clarify it : bad bitstream can cause losing connection or
damaging the hardware. here damaging hardware means ??

              so if i used bad bitstream , then is there  any way to keep
camera again to its default setting.?
