[USRP-users] E100 uhd.git build

Hi all,

I'm experiencing some weird behaviour as far as UHD building from
source is concerned on an E100 platform.

I've done the following:

$ git clone git://ettus.sourcerepo.com/ettus/uhd.git
$ cd uhd/host
$ mkdir build
$ cd build
$ cmake
-DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/arm_cortex_a8_native.cmake
-DENABLE_E100=ON -DENABLE_USRP_E_UTILS=TRUE ../ && make && make install
&& ldconfig

(Actually this step is made through a cross-compiler setup on
a distcc server, but it's done with no complains).

Everything goes fine. Then:

$ cd utils && python uhd_images_downloader.py
Downloading images from:
http://files.ettus.com/binaries/master_images/archive/uhd-images_003.004.003-205-g4896bf78.zip
 6.95 MB/6.95 MB (100.00%)
Images successfully installed to: /usr/local/share/uhd/images

Then, I guess, I should be ready for a reboot to let the E100 load
the new firmware and fpga images.

When it's online again:

$uhd_find_devices
linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500;
UHD_003.004.003-227-g0ccf3453

No UHD Devices Found

$ uhd_usrp_probe
linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500;
UHD_003.004.003-227-g0ccf3453

Error: LookupError: KeyError: No devices found for ----->
Empty Device Address


-----------------

What am I missing here?

Any help would be really appreciated!

Thanks!
Antonio
