[Discuss-gnuradio] Unable to open USRP-E100

[Praveen Vikram]

Hi,

I recently got the USRP E100. Read the wiki page at http://ettus-apps.sourcerepo.com/redmine/ettus/projects/usrpe1xx/wiki/FAQ.
I decided to compile the latest version of UHD. 
But after following the steps listed in the wiki page I'am able to find the USRP using uhd_find_devices but when I try to run uhd_usrp_probe I get error saying there is an IOError.

Here is the screen dump:

address@hidden:~# uhd_find_devices
linux; GNU C++ version 4.5.2 20101204 (prerelease); Boost_104100; UHD_003.001.002-b9280e8

--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
   type: usrp-e
   node: /dev/usrp_e0
   name:
   serial:


address@hidden:~# uhd_usrp_probe
linux; GNU C++ version 4.5.2 20101204 (prerelease); Boost_104100; UHD_003.001.002-b9280e8

-- Opening USRP-E on /dev/usrp_e0
Error: EnvironmentError: IOError: Failed to open /dev/usrp_e0

Also when I tried running ldconfig after compiling and installing UHD from git it gave me the following error:

address@hidden:~# ldconfig

ldconfig: /usr/lib/libstdc++.so.6.0.14-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

I also updated to the latest firmware.

Any help will be appreciated. Do I have to use opkg and revert to the uhd packages?

Thanks,

Praveen
