Re: [Discuss-gnuradio] Unable to open USRP-E100

[Praveen Vikram]

Update:

I tried recompiling after git pull <url> next.

Now, uhd_find_devices lists my E100 with a serial number but when I try to probe it gives me the following error:

address@hidden:~/Work/code/uhd/host/build# uhd_usrp_probe 

linux; GNU C++ version 4.5.2 20101204 (prerelease); Boost_104100; UHD_003.001.002-f312ceb

-- Opening device node /dev/usrp_e0...

Error: RuntimeError: Expected module compatibility number 0x1, but got 0xffffffff:

The module build is not compatible with the host code build.

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

-- 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
