Dear Rahul
The program test_fusb is not installed in the computer's path. I can be found
in ../usrp/host/apps along with several others such as test_usrp_standard_tx
and test_usrp_standard_rx. In all three cases these programs are invoked by
navigating to the ../usrp/host/apps directory and typing:
./test_usrp_standard_tx
The "./" means execute the program in the current directory and not to search
the computer's path. You can see your path with the command "echo $PATH" from
a terminal prompt.
I have been recently using usrp_siggen.py instead of test_fusb or
test_usrp_standard_tx. This Python scipt is in gnuradio-examples/python/usrp
along with a couple of others such as usrp_oscope.py which I havent quite
gotten to yet.
All of these load the firmware.ihx and usrp_fpga.rbf files and change the
blinking led #0 from once a second to twice a second or so.
The usrper program is in the path, but it doesnt load either firmware.ihx or
usrp_fpga.rbf. However, once the firmware.ihx and usr[_fpga.rbf file are
loaded then the command 'usrper led1 on' and 'usrper led1 off' should produce
visible results.
Currently, I can run usrp_siggen.py with no problem and change the frequency
and amplitude of the resulting sine waves and admire them on a scope. I will
be here working through some Python details for the next three days and if
you look at the previous post, it is a combination of usrp_siggen.py and my
current thoughts, in an *almost* operational program.
It will load firmware.ihx or usrp_fpga.rbf if requred. When its window is
closed, then the original usrp_siggen code executes sg.start and starts the
default 900Khz sine wave at a volt or so amplitude.
I hope this helps you a little bit. Please let us know your progress as you
work through the issues.
