UHD Announcement - August 31st 2010 - USRP1 support

Hello list,

USRP1 support is now part of the UHD. Fetch the latest host code and
images: http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki


Firmware and FPGA images:

You can get the most recent pre-compiled images here:

And the application notes for installing and or building them:

Completeness of the USRP1 support:

Using either daughterboard slot is supported, however only single
channel operation is possible for now. We are 90% of the way to
multi-channel operation, we probably need a new top level wrapper for
it.

8bit sample support is not in there yet. This will eventually manifest
into an API call to set the over-the-wire data type.

I believe that everything else is in there…

Dont forget to take a look at the USRP1 application notes:

USB Support:

The USB support in UHD relies on libusb 1.0 which has only been tested
and confirmed working on linux for now. If libusb is not found at
configure time, USRP1 support will not be built. Linux users will need
to install the libusb-1.0-dev package.

See the build guide:
http://www.ettus.com/uhd_docs/manual/html/build.html#libusb

Special thanks to Tom T. for the USB framework for UHD and the USRP1
support!


USRP1 timestamp support:

The current USRP1 FPGA + host code has no concept of timestamps. In
other words, the UHD rx and tx metadata is completely ignored.

For those that want to hack on USRP1 to add timestamps capability, I
recommend cloning the uhd on a github to collaborate. All of the FPGA
and firmware code is also in the uhd repository.


Feedback and testing is always welcome.

I take it then, that USRP1 under UHD doesn’t require new firmware on the
USRP1?

Images are automatically loaded at runtime after each power-cycle; so
its not an issue to worry about what images your device has as it is
with USRP2.

That said, the FPGA images are identical to the ones checked into the
gnuradio tree. However, the firmware was slightly modified to make the
spi interface more sane. So, no, the firmware image is different than
the gnuradio build. Should it affect you? no.
