Looking through the header files this looks really useful, thanks for the hard work guys :)
I'm having some problems getting it to work though, I've downloaded the firmware/fpga builds from the link and with these running python/find_usrps isnt able to find the usrp2 - its fine with the latest non-vrt firmware. The leds flash and then the bottom right 2 leds come on. I've had a quick look and I think find_usrps/usrp2.source_32fc should still work. I haven't tried using firmware compiled from the git repository yet so I'll try that and try connecting with a TTL cable attached to the debug port tomorrow unless anyone else has a similar problem/ideas? (Unfortunately I've only got access to the latest Xilinx ISE which I understand (as ever) breaks compatability with fpga code written for previous versions. I havent had much luck synthesising with it so far anyway, although I've only really done a quick try so far -- so I cant try making my own fpga file as well) Cheers, Tim On Wed, Dec 23, 2009 at 4:12 PM, Josh Blum <j...@ettus.com> wrote: > i pushed the patch, thanks! > > -Josh > > > Doug Geiger wrote: > >> Josh Blum wrote: >> >>> Folks, >>> >>> There has been much work in the past few months to get the VITA Radio >>> Transport (VRT) protocol working with the USRP2.
