Hi everyone,
I am new to gnuradio, so this may be basic. Searching online, I couldn't
find a solution (other than advising to ditch the PC I am using :) )
I am running the usrp_siggen.py script to generate a sin wave using the
2.4GHz board and I get the following error when running the script:
uUuU == USRP underrun (not enough sample ready to send to USRP sink)
The documentation on: http://gnuradio.org/trac/wiki/UsrpFAQ/Gen
says to avoid cache crippled PC :) (is there another solution to this?)
I have an HP laptop and am running Ubuntu:
