I'm trying to do a Rx->Tx Loopback on the Fmcomms2, connected to a ZedBoard.
I've been able to do it by modifying the libiio:iiostream example, but when trying to configure the loopback with the Fmcomms2 advanced plugin nothing happened.
I've noticed that, unlike other tabs, there is no "save settings" button in the BIST tab. Yet there was one in previous versions (see screenshots in FMCOMMS2/3/4/5 Advanced Plugin [Analog Devices Wiki]).
So is there anything else to do beside clicking the loopback:Rx->Tx button ?
