Re: [Discuss-gnuradio] UHD USRP2 Board Syncronisation on Firmware

[Matt Ettus]

Marc,

This mailing list is only for discussing GNU Radio related topics.  We 
have another list for users of USRPs with other software like Simulink 
and Matlab, which would be a better place to ask your question.  You can 
find it here:

Thanks,
Matt
