Re: [Discuss-gnuradio] How can I build component usrp on E100?

[xi yang]

Hi, Marcus and Sean,

I'm a little bit confused by the relationship between UHD and gnuradio.
I thought we can use either UHD or gnuradio, just UHD provides some unique interfaces for the products from Ettus.
Do you mean that our old ofdm codes that work on USRP1 cannot be used anymore?
We are working on Non-Contiguous OFDM and our previous codes can disable some subcarriers on USRP1.
Because we want to do FFT on FPGA, we change to use USRP E100, but codes on the host are useless now?

I tried next branch, use
"git checkout next"
right?
However, usrp component is not available either.
SO basically we have to wait for the next release?


Thanks,
Yooxi

Hi, all,

I have updated the kernel modules to 3.0.0 for my USRP E100.
UHD is successfully built and benchmark_rx_rate in
uhd/host/build/examples works.
I further installed the gnuradio according to the usrpe1xx-FAQ
http://code.ettus.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ

$ git clone git://gnuradio.org/gnuradio.git
$ cd gnuradio
$ ./bootstrap
$ ./configure --disable-volk --disable-usrp2 --disable-usrp1
--disable-gr-video-sdl CFLAGS="-march=armv7-a -mtune=cortex-a8
-mfpu=neon -mfloat-abi=softfp -O3" CXXFLAGS="-march=armv7-a
-mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -O3"
-with-qwt-incdir=/usr/include
$ make
$ make check
$ su
# make install
# ldconfig

YOu'd only need the "usrp" component if you planned to plug a USRP1 into the E100, instead of using the on-board USRP platform.

The examples you quote haven't quite yet been converted to use the UHD interface, which is what is used on the E100 platform.  But Tom is very
  close to releasing the converted-to-UHD examples.
