[hpsdr] Updating HPSDR rig

[Terry Fox]

Hello all.  I am firing back up my HPSDR rig.  I started by updating the 
FPGA firmware on Mercury and Penelope.  I ended up having to use Quartus and 
a real USB-Blaster, for some reason I could not get Ozy to update the 
firmware.

I have the case and Atlas, an LPU, Mercury, Penelope, Alex, and Excaliber. 
Since I update the firmware, the LPU seems to not be able to supply enough 
5V to the boards.  In fact, It cannot support just the Mercury and Penelope 
boards (and Ozy).  I can run all the rest of the boards fine, but if I try 
to run just Mercury and Penelope, the LPU 5V shuts down after about 2 
minutes.

Is this normal?  Has the firmware in Penelope (and Mercury) been updated to 
use enough more of the FPGA fabric that the LPU cannot support this anymore?

Would Metis draw less power than Ozy?  I am doing this in preparation to 
moving to a Metis that I'm about to order.
Thanks in advance,
Terry, WB4JFI
