After some bad judgement on my part, my E100 is back up and running. Now with the USRP1 attached, I can transmit up to 4 Msps before I get underruns using tx_timed_samples. The scope output checks out as well. With gnuradio, however, I get underruns rather severely at any sample rate; I didn't do any digging to find out why. > 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 ???
