[hpsdr] Hermes trouble

[Dave Larsen]

Glen --

Sorry to here about the 0dbm issue.  Not sure what to make of that.

as for HPSDRBootloader and the HPSDRProgrammer_nopcap

The  HPSDRProgrammer_nopcap should never use the j12 as the software is
using the same UDP protocol that PowerSDR uses to talk to the board.  This
requires that there be a valid firmware loaded so that the software can
connect.  If neither HPSDRProgrammer_nopcap or PowerSDR connect your board
the next step is to:

Put the J12 and use the HPSDRBootloader,  this software does not need a
valid firmware loaded and does not use UDP protocol.  It does require a
valid bootloader firmware loaded in the board, placed there by the
manufacture and it uses the pcap protocol.    To use this you will need to
have administrator privileges and the pcap library loaded.

On Linux you simply

sudo apt-get install libpcap

On window you will need to download and install Winpcap.  The Winpcap
license is free but they require that we can not redistribute the library
and the end user must get it from there website.

Then the HPSDRBootloader checks to see if the MAC address of a Metis or
Hermes board on the specified network.  If you get to this point is often a
good idea to eliminate ethernet switches and routers between your computer
and the board as some routers may restrict the range of the pcap packets.
it does work well thought some of these but at this point you should
eliminate variables in your problem.

If the board is still functioning, you should be able to re-program the
firmware.  If it fails, it is either a missing bootloader in the board or a
hardware problem.

I hope this helps
