Hi,
I'm having some trouble getting my USRP board running with just about any
software. It always seems to die with "Can't find firmware: std.ihx".
I've
tried a whole array of applications including usrp_fft.py and similar,
usrp_probe and then also the C++ progs (test_usrp_standard_rx and the
like).
It dies with the same complaint when running the C++ software that we're
busy writing. It fails on the line "usrp_standard_rx::make( ... )" where
the
firmware file is specified. It is currently blank (i.e. default) but even
if
the file is specified explicitly, it still claims that it cannot be
found.
From what I understand from what is going on in "usrp_prims_common.cc"
if
the user specifies a path it should override the default one. Exactly how
it
formats this path I can't really keep track of and I think something is
going wrong there.
Under typical installations the path is constructed with
"/usr/local/share/usrp" appended with rev2 or rev4 and the filename.
If environment variable USRP_PATH is set, then the revision and
filename are appended to that path instead. Read permissions are also
checked before the path is returned.
As you already suspect, the problem is most likely something minor.
Try printing out the path in the find_file() call to see what you're
searching for.

I had it working on Ubuntu 9.04 x86 but it stopped working when I updated
to
10.04. I tried reinstalling gnuradio 3.2 several times. And also tried
the
versions from synaptic but always came down with the same error. I've
since
wiped the system and installed Ubuntu 10.04 x86_64 with new 3.3.0 version
of
gnuradio but the problem continues.
I do have "usr/local/share/usrp/rev4/std.ihx" and all that goes with it.
I
can also load the firmware with usrper and then put LED1 on and off so
the
USRP seems to be working correctly.
I do get the feeling I'm missing something very obvious here because it
seems the last instances of this sort of problem date back to 2007. Still
I
just can't put my finger on whats wrong.
Any advice would be greatly appreciated.

Craig
