hi,evryone i am troubled with running usrp demo. i believe i have configured my ursp correctly because there is data displayed while running usrp_spectrumsense.py. however, when i tried benchmark_rx and benchmark_tx on two computers, i got nothing to indicate that the device was recieving
on the rx side : [r...@localhost digital]# ./benchmark_rx.py -f 5G -r 500k db_xcvr2450_rx: __init__ Creating new xcvr2450 instance xcvr2450: __init__ with 48b9d10f: 0 >>> gr_fir_fff: using SSE the program stoped here and waited without an end. on the tx side we can see: [r...@localhost digital]# ./benchmark_rx.py -f 5G -r 500k db_xcvr2450_rx: __init__ Creating new xcvr2450 instance xcvr2450: __init__ with 48b9d10f: 0 >>> gr_fir_fff: using >>> SSE............................................................ ..................................................................................... ..................................................................................... ..................................................................................... ..................................................................................... ....................xcvr2450__del__ this question has already been asked and discussed by others for some time. unfortunately, their advices did not settle my problem. i wonder where benchmark_rx stops and what it is waiting for.so i tracked the codes. my_top_block.wait() in benchmark_rx.py which is defined in the class top_block calls top_block_wait_unlocked() gnuradio_swig_py_runtime.py. the definition of the function is followed: def top_block_wait_unlocked(*args): """top_block_wait_unlocked(gr_top_block_sptr r)""" return _gnuradio_swig_py_runtime.top_block_wait_unlocked(*args) in the head of the file gnuradio_swig_py_runtime.py is import _gnuradio_swig_py_runtime. when i want to learn more about the function _gnuradio_swig_py_runtime.top_block_wait_unlocked(*args), i can just find nothing other than two files, _gnuradio_swig_py_runtime.la and _gnuradio_swig_py_runtime.so, which seem to solve nothing. i have no idea where the definition of _gnuradio_swig_py_runtime.top_block_wait_unlocked(*args) is. and i would also appreciate it if anyone can share anything about using benchmark_rx/tx. thanks in advance! philips.c.c _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
