Jonathon,
Thanks, I found that I needed to add
"$LOCALPREFIX/lib/python2.7/dist-packages:$PYTHONPATH" to my python path
in order for it to see the OOT modules.
So, now I'm on to my next problem. When I execute the python script on
the E310 I now get another error:
[INFO] [0/Radio_0] Performing CODEC loopback test...
[INFO] [0/Radio_0] CODEC loopback test passed
Traceback (most recent call last):
File "e310_rx_spectrum.py", line 214, in <module>
main()
File "e310_rx_spectrum.py", line 203, in main
tb = top_block_cls(freq=options.freq,
rfnoc_gain=options.rfnoc_gain, rx_gain=options.rx_gain)
File "e310_rx_spectrum.py", line 101, in __init__
self.tutorial_gain_0 = tutorial.gain(
AttributeError: 'module' object has no attribute 'gain'
I've seen on other posts that this has something to do with an error
when importing the tutorial module. Or that maybe, something needs to
be added to a header file. I've verified my xml files by comparing them
with the project files downloaded from the ettus web-site as described
by the application note AN-823 (Getting Started with RFNoC Development).
Sorry for the questions on basic operation. If I can get a
configuration that goes from start to finish I can expand from there to
more complex operations. I think the embedded E310 environment is
making it more complicated than other environments that don't require
cross-compilation.
Thanks,
Mike

Hi Mike,
The might be due to the PYTHONPATH env variable not including the
directory where your OOT module is installed. Try looking for a
directory like /usr/lib/python2/dist-packages or similar and adding
that to PYTHONPATH.

I got an error when running a gnuradio python script on the E310.
The
python script was created on the host machine in GRC and then copied
(scp) over to E310. I've done this successfully with built-in
modules/blocks. Now that I've created a custom FPGA, I've
successfully
updated the XML files in the OOT RFNoC module so that the new block
shows up named correctly when I run "uhd_usrp_probe".
The gnuradio error happens when I try to import the new module (in
this
case "import tutorial").
root@ni-e31x:~# python e310_rx_spectrum.py
Traceback (most recent call last):
File "e310_rx_spectrum.py", line 19, in <module>
import tutorial
ImportError: No module named tutorial
root@ni-e31x:~#
On the host side I am able to see the new OOT module and choose
the new
block (in this case, "gain") and create the new grc block diagram. I
compile the GRC diagram and then copy the python script over to
the E310.
I created a new "build-arm" directory in the rfnoc OOT directory (in
this case, "rfnoc-tutorial"). I performed a cmake, make, and install
similar to the other cross-compile steps with the result that I
see the
files being installed into the /e300 directory (i.e. the directory
that
is sshfs shared with the E310). But, I still feel that something is
missing since the embedded version of gnuradio is unable to locate
the
new tutorial module.
Any suggestions? I feel like I'm real close...
Thanks,
Mike
