Rx tune fails "Unable to tune to VCO=1900000000" #23

Closed takgr closed 5 years ago

takgr commented 5 years ago

I don't know if this is the right place to open this issue, if not please let me know to move it. Trying to tune XTRX to 950MHz, Rx tune fails and there is a core dump. I use Soapy if that matters, and USB3 connection to XTRX

Debug log follows:
