Creating SD image for Ettus N310

Dear all,

I recently bought a new Ettus USRP N310. It is booting approprietely with its original SD card and I can get a response on ping requests at 192.168.10.2 within few seconds from startup.

My issue is when I tried to communicate with the board with matlab 2021a, the USRP was not discoverable.

I found later that the UHD version is different (3.15 on my laptop, and 3.11 on USRP or lower I forgot).

I kept the original SD card aside and tried to create a new one using USRP support packagges for communication toolbox. The image was downloaded "n3xx_common_sdimg_default-v3.15.0.0.zip"

I extracted it and used "usrp_n3xx_fs.sdimg" to validate the image and the process suceeded.

I inserted a 16GB SD card and started the writing process, but it failed after a while without seeing any data transfer between my laptop and the SD card via the system monitor.

I inserted a 32GB SD card and started the writing process, I was seeing data transfer between my laptop and the SD card via the system monitor, but a timeout error was rised when the writing process was very close to the end.

I retried this process with both SD cards but always getting the same error.

Does anyone have an idea how to solve this issue?

The USRP N310 is not working on matlab until this moment.

Thanks,

Hello Fedi! I have experienced the same problem (with a N310).

I personally solved it by doing the following: First, format the micro sim card (I did it with

win32diskimager), delete the possible partitions and at that moment write the .sdimg

In my case, at the moment I still have problems with the ethernet connection, matlab does not recognize the usrp N310 (when doing findsrdu). If you have any possible solution or suggestion write me. As well as if you have any other questions.
