USRP2 not Found with UHD on SD Card

GNU Radio
1

Hi
I have installed UHD on SD Card. When I turn on USRP2, LED “D & F” on (
SD card is working properly).
Ubuntu 10.04 with GNUradio 3.2.2 has been installed on PC.
When I run the command " sudo find_usrps", I got " NO USRP2 Found".
The command “sudo find_usrps” worked fine with my previous SD card.
I also have tried the command “sudo uhd_find_devices”, and got " command
not found".

Please guide me…wether I have to install something on my PC to work
with UHD (SDcard).

Waiting for Response

That command “find_usrps” for the old gnuradio driver and not for uhd.
You will want to use “uhd_find_devices”.

I also have tried the command “sudo uhd_find_devices”, and got " command not
found".

Hi

  1. I have installed both the firmware and FPGA images on the SD card but
    when i use python program for test for usrp2 i.e “usrp2_probe.py” its
    shows message that no USRP2 found.

  2. when i use command sudo uhd_find_devices it doesn’t find any device
    in fact its give error that there is no shared file libuhd.so. No such
    directory available.

I have used the UHD API.

why this is happening?

I have covered all the steps. Am i missing something???

Thanking you.

Does UHD work with 3.2.2? Can you ping the USRP2? It will probably be on
your second ethernet port at address 192.168.10.2 ? What does ifconfig
say?
