Problem with inband USRP

Hi,

When running test_usrp_inband_rx, it gets stuck because it does not
receive any data. Is there a problem with the code in the trunk?
(revision #10191). The USRP is working fine with the legacy code
(e.g. usrp_rx_cfile). Here’s the output of the program (with the
verbose flag set in usrp_server):

[USRP_SERVER] Initializing…

Thanks for your help.

The problem seems to be in usrp_rx.cc, line 123:

d_urx =
boost::any_cast<usrp_standard_rx *>(pmt_any_ref(pmt_nth(1, data)));

This code throws the following exception:

exception: boost::bad_any_cast: failed conversion using boost::any_cast

I tried with boost 1.35 and 1.37, with the same result.

Can somebody help?

Thanks.
