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

$ 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"
$ make
$ make check
$ su
# make install
# ldconfig

Because the component usrp is skipped, when I try to run
the usrp module cannot be found.
ImportError: cannot import name usrp

The results of configure are as follows. How can I build usrp on E100?
Is that because the sdcc version is not high enough?
I see this in configuration.
"checking sdcc_version "2.8.0"... 2.8.0
Not building component usrp."

Thanks, Yooxi ********************************************************************* The following GNU Radio components have been successfully configured: config gruel gnuradio-core gr-msdd6000 gr-audio gr-atsc gr-cvsd-vocoder gr-gsm-fr-vocoder gr-noaa gr-pager gr-radio-astronomy gr-trellis gnuradio-examples gr-uhd docs You my now run the make command to build these components. ********************************************************************* The following components were skipped either because you asked not to build them or they didn't pass configuration checks: volk gcell usrp usrp2 gr-usrp gr-usrp2 gr-gcell gr-comedi gr-gpio gr-radar-mono gr-video-sdl gr-wxgui gr-qtgui gr-sounder gr-utils grc gr-shd These components will not be built.
