I'm told the files should flow into the overo build system soon also. To build, (short form for people who can build their own sw), Edit the gnuradio_svn.bb and boost_1.36.bb files and comment out the DEFAULT_PREFERENCE="-1" lines with a #. bitbake gnuradio-image wait a long time. After you get it loaded, start testing :) dial_tone.py should work and the benchmark for the fff dotproduct should give you something like this: balis...@beagleboard:~/oe/tmp/work/armv7a-angstrom-linux-gnueabi/gnuradio-3.1.3+svnr10302-r6/trunk/gnuradio-core/src/tests$ ./benchmark_dotprod_fff generic: taps: 256 input: 4e+07 cpu: 1269.242 taps/sec: 8.068e+06 cortex_a8: taps: 256 input: 4e+07 cpu: 49.156 taps/sec: 2.083e+08 Note, I NFS mounted my home dir on teh beagle and ran the benchmark command on the build machine first.

Hopefully, there is a Gumstix board with DSP at some point. I did take a quick look at this over the weekend. We can build gnuradio 3.1.2 with OE, but not the version in subversion, which I use for adding the NEON code. I need to debug a problem finding python headers or something.

Okay, thanks for the help, we'll start looking into it and maybe purchase a beagle board for evaluation. By the way, there doesn't seem to be a link to the patch in 1) (unless I am slow and this is some dark humor ;) Dan On Thu, Jan 15, 2009 at 10:37 PM, Philip Balister wrote: > On Thu, Jan 15, 2009 at 12:51 PM, Dan wrote: > > Hi, has anyone had success porting GNU Radio to Gumstix?

It > would nice to connect Gumstix to the USRP at least. At this years SDR Forum I did a demo of Gnu Radio running on the Beagle Board (http://www.beagleboard.org). The Beagle Board is fairly close to the gumstix overo product line. You should be able to build gnuradio radio for the overo via OpenEmbedded. I haven't had time to try this, but I plan to in February, if I can get some free time (as in no other paying work). The list of issues at the moment: 1) GNU Radio is obsessed with floating point :) For my demo, I converted one of the FIR filters to use the NEON co-processor. GCC is not real good at genereating good code for NEON, so I used GCC inline assembly. The patch is here : 2) The USRP code depends on knowing internal structures of libusb-0.12. Angstrom is using the libusb-1.0 code which breaks the USRP. I can build Angstrom with libusb-01.12, but it is a "nuisance". We need to work though this issue anyway for GNU Radio to run as distros convert to libusb-1.0 anyway. 3) The Overos have an EHCI host, which is the best place to attach the USRP, but you will need a hardware mod to make this interface work. Expect an email from Gumstix about this. In the past, I've had some success on the MUSB port also. This needs work. 4) We need to add support in GNU Radio based on the patch in 1. 5) I can run bits of "make check" by mounting the OE build dir via NFS, but there are some libtool issues to resolve. 6) Convert more floating point to use NEON. 7) Add better support to GNU Radio for suing data types other than float. (Maybe not as critical for the OMAP3, but there are some interesting platforms that would benefit from this) 8) Future Gumstix products may use the OMAP3 with the DSP. (The Beagle already has the DSP) Moving algorithms to the DSP should be interesting. This DSP is not floating point, see 7. Hopefully, this gives people an idea of how to migrate GNU Radio off "big iron" onto smaller, lower power, hardware. I'm glad to answer specific questions and do plan to work on OMAP3 support as I have time.

If you have OE running for the Overo, running "bitbake gnuradio" should work :) There's more to it than that, but I need to set aside some time to properly answer the question :) Hopefully tonight.
