[Discuss-gnuradio] UHD with TVRX Rev 1

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
