I added some width to rx_format_is_valid, but I receive a "floating
point exception", as this:
address@hidden:/home/rocker/Tesi/My Works/GNU Radio
Experiment/rx_cfile# ./usrp_rx_cfile.py -m -f 1.575G -w 1 -R A -d 16 -N
1000 -g 90 -s output.samples.1
Upload new firmware!
Using 1 bit sampling
format = 0x21f
set_format = True
Using RX d'board A: DBS Rx
USB sample rate 4M
Floating point exception
(same script attached in the mail above)

I can do it. Please give me the right way...
