Hi Eric
I just tried flashing the SD ram as instructed on the web. It didn't change much. Now when I run the two scripts I randomly get either "segment fault" or some lines of traceback print with a runtimeerror "Unable to retrieve daughterboard info. I also tried  another USRP2 with newest FW. It responded the same way. This however had the DBSRX mounted (unfortunately not modified for USRP2 since we didn't know until yesterday). I
Maybe you could help me if I write exactly what I do
with RFX1200 mounted
If I write: sudo ./usrp2_fft.py -f1300e6
I get this response:
Traceback (most recemt call last);
