As a new user I have just made the uhd_fft.py to display something. I
the LFRX daughter board for initial testing. I have a concern with the
front panel LED E light. While the uhd_fft.py is working, both the LED C
and E lights are on solidly which is expected. When shutting off the
uhd_fft.py, the two lights went off also. But the LED E light starts to
first slowly blink and then to pick up speed in blinking. The E light
the ref lock, I am guessing the rx board doesn’t like not having a ref?
got really annoying watching the fast blinking light. I fear that this
might not be good for the overall health of the system. The only to cure
this seem to be power cycle, which is not preferred. What should I do to
prevent this or to ensure that everything is working correctly and there
no system complaints?
