Hi,
We have recently installed the GNU Radio Software, and got the USRP with
2
daughterboards. We have seen a couple of instructions for USRP to obtain
the
necessary firmware files but the problem is those documentations date
back
to 2005 and I guess there are some changes from that time. For example I
have found this instructions from a documentation from 2006
"Plug the Power cord into the usrp. You should see a green LED
(hidden
under the “RXA” daughterboard, which is nearest to the USB connector)
blinking at about 2Hz (twice a second). When a USRPapplication starts,
the
USRP will load two ï¬les from the directory
/usr/local/share/usrp/rev2:usrp_firmware.ihx and usrp_fpga.rbf. The
blinking
LED should slow down to 1Hz (once a second)
after the usrp_firmware.ihx ï¬le was loaded successfully. Ensure the ï¬le
usrp_fpga.rbf is in that /usr/local/share/usrp/rev2 directory. Note that
if
you install the usrp module from CVS, it won’t be there. You’ll have to
get
the tarball of usrp-XXX.tar.gz from the GNU Radio download page, extract
this one ï¬le, copy it to the right place.
cp usrp-./fpga/rbf/usrp_fpga_rev2.rbf
/usr/local/share/usrp/rev2/usrp_fpga.rbf "
One problem is that we only have multi_2rxhb_2tx.rbf, std.ihx,
std_2rxhb_2tx.rbf, std_4rx_0tx.rbf usrp_radar_mono.rbf and
usrp_sounder.rbf
files under rev2 file, so does anyone know whether the files under
/usr/local/share/usrp/rev2 has changed recently. Another thing is that
we
have installed the gnu radio software under another file so the exact
path
for our case is /opt/gnuradio/share/usrp/rev2. Does this make any
difference? I mean do we have to do some extra things for USRP read the
necessary files.
