Hi
When I run it in USRP1 nodes, I don't get the error as before, that
says it cannot find USRP1.
USRP1s didn't require any "wire format" or firmware/FPGA changes to
support UHD, so both "classic" and "UHD" programs will work,
with USRP1s provided that the daughtercard in use is "pre-UHD".
Development of the "classic" branch was frozen quite some time ago, so
any cards that are "new" won't work in anything but the UHD environment.
But the benchmark_tx program says "Failed to tune to center
frequency". I then tried to send it in 2 MHZ and also in 2 GHZ
frequency, but it still doesn't work.
What daughtercard are you using?
What rev of Gnu Radio are you using? I strongly suggest always trying
to run with some quite current.
