[Discuss-gnuradio] Re: Valve Problem

[Umair Naeem]

I tried with throotle block before Valve but same thing happens, flow graph 
seems to stop working. I think the problem is with Probe Avf Mag^2 block 
because when i removed this block the valve start working. Now a new thing 
happens, whenever I make it open using a variable during execution, the scope 
stops but when I re-enable (close) the valve again an error occurs that is,

usrp2::rx_samples() failed
usrp2: channel 0 not receiving

THere is one more problem when i try to run any flow graph in 64-bit machine. 
When I enable "Realtime Scheduling" to ON or when I try to change USRP2 source 
frequency or decimation value during execution (using a variable) the error 
occurs

Failed to enable Realtime Scheduling
