Re: [Discuss-gnuradio] UHD with libusrp ?

[Vanessa Quaranta]

I think that your solution is almost functional!

I installed like this : 
Ubuntu 10.10 (French version)
GNU Radio + UHD from git (GNU Radio 3.6.0)
libusrp-dev from apt-get install tool
openbts 2.6.0mamou

My USRP1 is patched to  52MHz. So I think it's the problem now.

If I run OpenBTS without using ../Transceiver52 in OpenBTS.config file, it start but crash after 2 seconds with these lines : 

1335942704.565352 3078735568: 
Welcome to OpenBTS.  Type "help" to see available commands.

1335942707.5675 ALARM 3069897584 TRXManager.cpp:85:clockHandler: TRX clock interface timed out, assuming TRX is dead.

Now, if I run OpenBTS with using ../Transceiver52, it crash before it started : 

1335942865.288961 3078358736:

So, I think the problem is the clock!
How can I patch GNURadio 3.6.0 or libusrp for that? 
With GNURadio 3.2.2 we need to patch files  from /usrp/host/lib/legacy/* files but with the newer version, I don't know how to patch these files..

Thanks a lot !

Looks like my accidentally missed the list in my last reply.

* I think installing the gnuradio whatever version you like -- for
gnuradio purposes is best.

* Install libusrp from source or from the software repository -- for the
purpose of compiling libusrp1 support in OpenBTS.

Here was my reply:
