[hpsdr] Hermes, no Firmware Update possibile

[Dave Larsen]

Chris --

I think you have the use of the various programs confused  Bootloader use
PCAP protocal like Wireshark. Programmer uses UDP only and depends on the
last version of the firmware having the capability to communicate the to
Programers software.

At the Last TAPR DCC, I gave a talk to explain this topic.  The video of
the talk is at *openhpsdr.org/videos <http://openhpsdr.org/videos>* it is
the 2017 talk or the paper is at *openhpsdr.org/publications
<http://openhpsdr.org/publications>*

either of these should answer your questions.
