I have been facing similar issues when starting developing on the E310 one
week ago. I have not resolved all of them yet. There are in fact more
questions once you start going deeper in the cross -compiling.


Ettus team, thanks for your great responses on the email list and for a
great product, however, IMHO I believe that it may be time to perform an
overall of the documentation which for the most part is disorganized and


Sorry for the harsh words

Subject: [USRP-users] Development for E-310.


Hi all,

I am building a library which I want to install in USRP E-310. The
instructions on the documentation page of USRP E-310 does not give much more


I am newbie for embedded linux development. 


I have certain questions which could be simpler as well. My questions are
based on the documentation page available on the link


In order to facilitate software development for the integrated ARM Cortex-A9
processor, a Yocto Project based SDK is provided in the download section of
our website.


Where is the download section? 


Does it refer to the one on http://www.ettus.com/product/details/E310-KIT
listed as Development frameworks ?


It refers to the Xilinx ISE. 


The following section will guide you through the installation of the
provided SDK on a Linux development machine.

Obtaining the correct SDK

It is necessary for the SDK version and the image version to match, to
ensure the versions of the software installed on the device and the version
of the software the SDK will build against match.

Although it is listed as SDK I have not able to find where it is at the
beginning later I got mine from this link




based on my understanding on this  command 




Is this correct step ?



Having installed the toolchain in the last step, in order to build software
for your device open a new shell and type:

$ .

This will modifiy the PATH, CC, CXX etc, environment variables and allow you
to compile software for your USRP E310 device. To verify all went well you
can try:

$ $CC -dumpmachine

which should return 'arm-oe-linux-gnueabi'.

I hope the above listed things are for setting up the environment variables
for libraries need for the development.


After that I didn't see any information on how I can build my own package
for this embedded platform. All I see is how to build UHD and GNURADIO for
this device ?


How or where should I refer to build my library for this embedded linux.


 There are tons and tons of documents available for other embedded devices
such as Beaglebone Black, Raspberry pi etc... which also runs on embedded
linux OS and I also see people using SDK to build applications for those


I am not sure about how I can do with this.


If anyone can help with this questions it may help me to understand further.
