Can't find my USRP2 in the program.

[Shreken]

Hi.

I'm having some problem with my USRP2.

when I do a uhd_find_devices I get:

type:usrp2

addr:192.168.10.2

But when I'm in a program (just the examples you get when you download usrp package) I get the error message:

Possible reason(s):
A runtime or configuration error occurred.
Code: 1299
Details: LookupError: KeyError: No devices found for ----->
Device Address:
    addr0: 192.168.10.2

If anyone has a clue, please help.

Hello Shreken -

Here are some suggestions:

1. Be sure your PC's IP address is set to the same subnet.

for example: 

your PC: 192.168.10.10 (subnet: 255.255.255.0)

your USRP: 192.168.10.2

2. Verify that the firmware has been updated on the USRP.

for USRP you'll need to remove the SD card to update the firmware.

The flashing process is outlined in greater detail on Page 18 of the user guide.

Please let us know how it goes!

Thanks for the fast reply.

my PC's IP address: 192.168.10.1 (subnet 255.255.255.0)

and my Firmware for the USRP is up to date aswell. Followed that example. But I can't ping the USRP either which it says I should be able to do in the manual.

btw.

I use:

Windows 7

Labview 2010

A few other thoughts:

1. Are you directly cabled to the device using the ethernet cable that came with the USRP?

(Cross-over cables and managed switches may pose a problem in communication)

2. Is the ethernet port on the computer 1Gig Ethernet?

(10/100 card and switches are not supported.  1 Gig E is required.)

Yes, I'm directly connected to the USRP2 with the cable I got from my teacher...assuming it's the same one. looks just like a regular ethernet cable.

But assume it's correct by the fact that I got it to kinda work with GNU-radio.

Yes I have a 1 gig ethernet.

Do you have UHD installed separate from the NI USRP driver?  While they can coexist, the firmware needed is specific to and ships with the NI USRP driver.

I have a USRP2 at my desk and just confirmed that it does respond to a ping command from the command prompt.

Secondly if the device does get into some type of odd state, there is an internal button that when held during start-up puts the device into safe mode.

I have the firmware included in the driver from here: http://joule.ni.com/nidu/cds/view/p/id/2679/lang/en

So it should be the correct one.

Where is this internal button? What does safe mode mean for URSP2?

[Shreken]

Today I tried to install the drivers and such on another computer just to see if there was something wrong with mine but i yield the same result.

I've tried both with the UHD drivers and with the drivers from NI

I've also tried to swith ethernet cable and this one seems to get a better response in the way that when I check my ethernet connection it only say "no internet access" instead of no network access as it did before.

[ErikL]

Sounds like it may have been the cable. "no Internet access" is the expected status. Maybe check Firewall settings too.
I'm starting to believe something is going on with the unit itself. Does the professor have another you could try?

Also, do you mind sharing your university and intended application?

[Shreken]

I've already disabled the firewall settings.

I'm a student at Chalmers University of technology, Gothenburg Sweden.

We are doing a BSc thesis project. The first application is to linearize a PA with digital predistortion.
