Re: [Discuss-gnuradio] UHD Driver in E100/Beagleboard

[Ingmar Meins]

I have been using the E100 for about two weeks and have no problems. I have built various GNU Radio Companion projects (text mode no wxgui) and they run fine. Are you trying to be too ambitious with your transmitted bandwidth?

The benchmark tests on mine indicate a maximum of 2.4Msps or thereabouts.


I have the following UHD version:
address@hidden:~# uhd_find_devices
linux; GNU C++ version 4.5.2 20101204 (prerelease); Boost_104100; UHD_0001.20101214211912.1

Cheers,

Ingmar

I was wondering about people's experience with the UHD driver on the E100 or the Beagleboard.  I am able to use it to receive IQ data from the USRP but I can't seem to transmit anything from it ... if I take the same flowgraph to a laptop I'm able to transmit IQ using the same USRP/daughterboard and the UHD driver however when I try to run the same transmitter on the Beagleboard and I check my spectrum analyzer I don't see anything

I already did a signal capture before sending to the USRP and made sure that there is data getting pushed through ... is there a problem with UHD/USRP sinking on the E100 and the Beagleboard ???  I also made sure that I'm using the latest UHD firmware on the beagleboard.


The following is the version info printed when I run the flowgraph:
linux; GNU C++ version 4.5.3 20110214 (prerelease); Boost_104500; UHD_0001.20110224034946.1


thanks
