[hpsdr] HPSDR – FPGA updating

HPSDR – FPGA updating

The process we currently use to update the flash EEPROM on the Mercury and
Penelope boards was only ever intended to be an interim solution until we
had a more convenient way of  doing it.

Unfortunately, the volunteer who was going to undertake the project was
unable to continue and the project has languished for a while.

Basically what we do at the moment is to load some code into the FX2 on
Ozy that makes it look like and Altera  USB Blaster.  We then use standard
Altera command line programs in a batch file to load the new data to the
HPSDR board.

This requires the target board to be in the next Atlas slot to the Ozy board.

What is needed is a way to identify the position of each board on the JTAG
chain and send the new code to the appropriate board.  That way the boards
can be left in situ when we need to update their code.

The Altera  tools seem to allow you to identify what devices are in the
JTAG chain but that is a far as I have got.

Is there perhaps a volunteer who would like to tackle this project?
