USRP + Matlab error in Simulink

Hello! I'm attempting to execute the FM receiver demo in Simulink using my USRP N210. I followed the directions for connecting the USRP and when I run findsdru it sees the device at IP address 192.168.10.2. The problem is, when I run the Simulink demo I get the following error:

Error reported by S-function 'usrp_uhd_sfunrx' in 'sdruFMStereo/SDRu Receiver/usrp_uhd_sfunrx': Could not execute UHD driver command in 'createDriver_c': Could not create a UHD driver using IP addr '192.168.10.2'. Attach a device at the specified address, correct the specified address to match an already attached device, or continue to work in off-line mode.

I know the USRP is being recognized in MATLAB and is connected correctly and the IP address is correct. Does anyone have any advice how to fix this error? Thanks!

Hey Wesley. I am having the same problem. I am getting the response from the address 192.168.10.2 when i give command "findsdru" but when i try to run the demo it gives out the same error which you got. Did you find out the solution to this? If yes please reply

Thanks, Madhura

It is possible that firmware (i.e. the FPGA image) is not compatible with the UHD software version used in the blocks and System objects. Please check your firmware version and make sure that it matched the following:

• For 11a, the firmware/FPGA image must be 003.000.001.
• For 11b, the firmware/FPGA image must be 003.002.003.

You can confirm that you have the right version of firmware/FPGA loaded by running an Ettus executable, uhd_usrp_probe. It can be obtained via a binary distribution at http://files.ettus.com/uhd_releases/<firmware_release_number/>, where firmware_release_number is either 003_000_001 or 003_002_003.

You can find the instructions to download the images at: http://files.ettus.com/uhd_releases/003_000_001/images-only/ or http://files.ettus.com/uhd_releases/003_002_003/images-only/
