[hpsdr] Ozy LED D1 flashing

[Joe Martin K5SO]

Anyone,

I have two Ozy boards that appear to work similarly when running w/ 
Janus on the Atlas backplane except that D1 on one of the Ozy boards  
is flashing at about 2 Hz or so whereas D1 on the other Ozy board is  
off.  All other LEDs on the Ozy board and Janus board behave normally.

I understand that the FPGA controls LEDs D1-D4 on Ozy and that the  
normal indication after FPGA load is LEDs D1-D4 off.  What does a  
flashing LED D1 on Ozy mean?
