[Elphel-support] camera bricked after re-flashing to elphel353-8.0.9 :(

I see. well, that it was not much help to point this 'issue' out at this
stage.

yes, this was my impression all along (has I didn't understand the
insistance on the NFS issues)

the frequency is correct (10 packets / sec in the beginning, then 1
packet / sec). and yes, they are all zeros.

can you elaborate on what 'wireshark' is?
