当试图执行一个使用 USRP 的 GNU Radio 程序时,我得到一个错误回溯,它(在 Python 中)通常以:
self.u = uhd.usrp_source(device_addr=args, stream_args=uhd.stream_args('fc32'))
File "/home/marcus/.usrlocal/lib64/python2.7/site-packages/gnuradio/uhd/__init__.py", line 122, in constructor_interceptor
return old_constructor(*args)
File "/home/marcus/.usrlocal/lib64/python2.7/site-packages/gnuradio/uhd/uhd_swig.py", line 2351, in make
return _uhd_swig.usrp_source_make(*args)
RuntimeError: LookupError: KeyError: No devices found for ----->
USRP 正在运行。
