View all threadsupdate image file
Dear all
I have problem as following to write image file in UHD. Is there anybody
help me to repair it?
I am interesting to know , where is my fault ?
Because I did all of process like routine method but I have not given
correct result to connect UHD to Matlab and USRP. first of all I should say
my Matlab version is 2012a and it is compatible with UHD_003_002_003
I reload Firmware and FPGA image file as following in command of terminal.

Hello Hossein
You just have to download and program the FPGA and Firmware that are
compatible to the version of the UHD you are using.
UHD_003.004.000-07c9d41 -> you will find it here :
http://files.ettus.com/binaries/master_images/archive/
To program the FPGA and Firmware, take a look at the UHD wiki: Go to
http://files.ettus.com/uhd_docs/manual/html/ and look for your device
manual. In my case for example, is USRP N210, so I go to UHD - USRP2 and
N2x0 Series Device Manual (
http://files.ettus.com/uhd_docs/manual/html/usrp2.html). There you will
find how to load images onto the board (in my case I load using the
network).
And for MATLAB, I see only warnings, not errors. Anyway, you will probably
have to load the FPGA/Firmware with the correct version as stated above.

Hi Hossein,
USRP Support Package for MATLAB and Simulink uses a version of UHD that may be different than a version of UHD that is already installed on your computer. From the command line outputs you sent, I can see that your computer has UHD version 003.004.000 already installed. Also, when you installed the USRP support package, UHD version 003.002.003 was installed and MATLAB uses that version. So, from an installation stand point, I do not see any problems.
The following messages are not errors:
Target sock buff size: 50000000 bytes.
Actual sock buff size: 1000000 bytes.
See the transport application notes on buffer resizing.
Please run: sudo sysctl -w net.core.rmem_max=50000000
They are suggestions from the UHD driver for better performance. I highly recommend you to follow this suggestion and run “sudo sysctl -w net.core.rmem_max=50000000” on your command line.
Hth,
Ethem
