Ok, I got the address correct, I know the usrp and daughtercard are there. I
can't get the simplest uhd_fft to run from GRC. I get the following message
on trying to execute, Generating the graph works.
-- Opening a USRP1 device...
-- Using FPGA clock rate of 64.000000MHz...
Using Volk machine: avx_64_mmx_orc
thread[thread-per-block[0]: <block gr uhd usrp source (1)>]: LookupError:
KeyError: Cannot find an item size:
The error output, as usual, has no meaning for me, entirely arcane. I'm
running Ubunu 12.04.4 64 bit and gnuradio installed without a burp. Actually,
the error message looks like something to do with multithreading. I tried the
archives, no help.
uhd_usrp_probe says the usrp1 is there and reports the daughterboards that are
really there.
so, need an interpreter, please.
Thanks, Don
