XCVR2450 draughterboard recoginition error (USRP2)

Hi everybody,

It seems that my USRP2 cannot recognize the XCVR2450 draughtboard

I got the firmware and fpga code from
http://code.ettus.com/redmine/ettus/projects/public/wiki/U2binaries, and
version of firmware is txrx_xcvr_raw_eth_20100608.bin, the version of
is u2_rev3_20100603.bin. And I use gnuradio 3.3.0. I tested it on two
computers, one has fedora13 OS, the other one has ubuntu10.4.

There is only draughtboard ID is shown when I run the usrp2_fft.py. I
this problem on the Internet, and did not find the solution. Other
who shown his/ her waveform (using the usrp_fft.py), it would show
Rx”. But in my case, it only show “0x0061”. The different between our
equipments is: I use USRP2 & XCVR2450, and he/she use USRP & XCVR2450.
am suspicious the program does not investigate the draughtboard
correctly. I
really want to know what’s happen and how to fix it. Welcome any review.
