Hi, has anyone had success porting GNU Radio to Gumstix? I would like to
install it on the Overo Earth board (OMAP 3503 with ARM Cortex-A8) if
possible. I searched around but couldn’t find much written about this. It
would nice to connect Gumstix to the USRP at least.
Any help would be appreciated,
OK, I’ve updated oe.dev so that you can build gnuradio (r10302) with
NEON implementation of the fff dotprod. 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 #.
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:
generic: taps: 256 input: 4e+07 cpu: 1269.242 taps/sec:
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. This needs work
