Umer, It looks like you are using the older libusrp2 code (usrp2_rx_cfile instead of uhd_rx_cfile). If that's the case, there are different images you need on the SD Card in the USRP2 to work with the WBX board. If possible, I suggest updating to the latest GNU Radio code ( http://gnuradio.org/redmine/news/5) and switch over the UHD. It will work for all daughterboards. Tom
