[Discuss-gnuradio] UHD with XCVR?

[Marius]

Hi!

Today I patched a USRP2, Rev 4.0 with the UHD_003.002.000-e03f7c7
images in order to use it with MatLab AND GNU Radio's GRC.
- This is the log taken from a Linux 10.4 LTS system, attached USRP2.
Previously this setup worked very well. Now that I updated... it's
broken.
The IP setup had been tested with both static IP, and without.

The LEDs D and F work. So the firmware and the fpga are loaded.

I used the latest available revision
(http://www.ettus.com/downloads/uhd_releases/master_images/) from the
master branch.
Since the update I cannot probe successfully with either usrp_probe or
with uhd_usrp_probe. Even if I change the kernel parameter according
to the UHD suggestion I don't get a working setup.

I'm using GNU Radio v3.4.0-101-g7e2b45b8 from the Git repo - built a
week ago or so. Since there's just one Firmware image for my USRP2,
and one FPGA image, and I tried n times... I guess there's something
else that's wrong.
I'd like to ask for a compatibility matrix: which UHD revisions work
with GNU Radio? For now it's try and error.

Best,
Marius
