[hpsdr] 14bit Hermes Schematic?

[Helmut]

Hi Martin,



Please never try to load 14 Bit Firmware into 16 Bit version or 16 Bit Firmware into 14 Bit FPGA config.  Appropriate firmware you’ll find on https://github.com/TAPR/OpenHPSDR-Firmware . Note that ANAN 10E or 100B stands for Hermes 14 Bit.



Anyway I would suggest to check the bootloader  section of the EEPROM and then try to go back to protocol 1. If the bootloader program doesn’t detect the board it can be necessary to refresh the bootloader section first by using an Altera USB Blaster.

Hi Helmut,

I have tried loading the 14bit Firmware V10.3 onto my friends 16bit Hermes with the

wrong small FPGA fitted and it does not work, I am now wondering if this is because

the bootloader.pof is not loaded as he also has the wrong flash chip in U1!

While I was trying things, I tried putting the 14bit firmware V10.3 into my fully functioning

16bit Hermes and it worked fine but I still had the problem with Pure Signal not working

all the time.

I wonder what version of firmware you are using on your 14bit Hermes which you told

me did not have that problem?

Seems that there is not a lot of difference between the 14bit and 16bit Hermes apart

from the different resolution ADC - still comparing schematics now the 14bit version has

become available...
