[hpsdr] Hermes, no Firmware Update possibile

[Phil Harman]

Hi Chris,

This happens if you don't have the Bootloader code installed in the Hermes 
EEPROM. In which case you have V3.1 in the lower half of the EEPROM and when 
you use the Programmer Software you load V3.3 into the upper half of the 
EEPROM.

When the FPGA powers up it looks for the code in the lower half of the 
EEPROM.  If the Bootloader code is installed this tells the FPGA to start 
loading code from the upper half of the EEPROM  i.e  V3.3.  Without the 
Bootloader code in place it will load V3.1.

So, simple solution, get or borrow a USB Blaster and install the Bootloader 
code into the EEPROM and all will be well!

Of course I did everything in the right way and give time for every step.
With Bootloader software it is NOT possible to program anything!
See my mails before...
The board is not answering with Bootloader software, with Programmer it 
does...
See my link to the picture...

Again, 2 different PC, different Setup, one has never seen any amateur radio 
software before.
3 different boards from 2 different users.
All boards from the same Company (Gerd Loch)

Back again to the main question, why is it not possible to get a response 
from the Board with the Bootloader Software?
Why is the Programmer Software working as you see in my link (screenshot) 
before but coming back with the old version?
So for both questions there must be only one answer, the boards are not 
entering the "update/ program" modus!
But why?

Is it possible that the 1st Stage loader, the pof file is broken while the 
use a corrupted file?
Sorry I've no USB Blaster here to test it now.

Chris,

After you place a jumper on J12 (for boot loader mode) then power cycle the 
Hermes board, wait a few seconds (or more) before clicking the “Program” 
button on the HPSDR Bootloader program.  This is necessary to allow the 
Hermes time to execute some code before loading the new code into the 
EEPROM.  If you are too quick in clicking the “Program” button the Hermes 
won’t have time to execute that code.

After the loading is finished loading the new firmware, remove the 
bootloader jumper on the Hermes board and power cycle Hermes.

Just a thought for you to consider.

73, Joe K5SO
