[hpsdr] WG: 14bit Hermes Schematic?

[Helmut]

Hi Martin,



I’m using Hermes_v10.3 firmware on the Hermes 14bit working sufficiently stable under Thetis.



If I recall correctly  the footprints of the LTC 2208 14bit and 16bit are quite identical, but

other I/Os of the FPGA  are used. Though  Hermes 16 Bit firmware should fail. BTW my Thetis v2.6.7

is asking for v10.3 or higher if older firmware versions are used.

Hi Helmut,

   Normally I would agree with you but if you have a new build Hermes board which has

inadvertently had the wrong (smaller capacity) FPGA installed it would be nice to see

if it can work with the smaller 14bit firmware before going through the pain of replacing

the FPGA with the correct one!



I would still be most interested to know what version of the protocol 2 firmware you are

running on your 14bit Hermes ?

I have been trying V10.3...
