Hi guys,
I am playing with the UHD and my TVRX rev 1 is not recognised.
Below is the output of uhd_usrp_probe. It looks as though my TVRX rev 1*
(*ID:
Unknown 0x0003) is not a recognised daughterboard in the current UHD
code:
$ uhd_usrp_probe
Mac OS; GNU C++ version 4.2.1 (Apple Inc. build 5666) (dot 3);
Boost_104601;
UHD_003.001.000-0aff497

I have tried altering the following function in “db_tvrx.cpp” located in
the
UHD code (uhd/host/lib/usrp/dboard) by changing the TVRX dbid to
“0x0003”:
UHD_STATIC_BLOCK(reg_tvrx_dboard){
//register the factory function for the rx dbid
dboard_manager::register_dboard(0x0040, &make_tvrx, "TVRX");
}
This change did allow the TVRX rev1 to be recognised by uhd_usrp_probe
but I
was still unable to tune it correctly.
Please could you point me in the right direction?
Thanks,
Mike
