Advice?: RF Loopback Test - Configure LMS - Failed

#1

Afternoon,

I purchased a new LimeSD. When I first powered it on and ran the LimeQuickTest the “RF Loopback Test” it is failing. The board is connected via USB 3.0 to a PC with Ubuntu 16.01. I pulled a fresh copy of the tools from the ppa:myriadrf/drivers repo. No Antennas are connected per the “The test should be run without anything connected to RF ports” guidance.

Any recommendations on configuration/etc I might have missed?

Thanks!

I’m not sure if its related LED 1 is blinking red/green also. I think that suggests “PLL is not locked” . Still googling what to do to resolve that also.
