[Discuss-gnuradio] need help on loading my own FPGA bitstream

[Yan Nie]

Dear all,

I'm trying to load my own FPGA bitstream. The .rbf file, however, cannot be loaded due to the errors as below. I've already copied the .rbf file under the directories /usr/local/share/usrp/rev2 and rev4 as well. 

Could you please guide me what the problem or the solution to solve the problem? Thank you so much in advance for the help.


Can't find fpga bitstream: ionosonde_tx_test0106.rbf
Traceback (most recent call last):
  File "./usrp_ionosonde.py", line 115, in <module>
    main()
  File "./usrp_ionosonde.py", line 91, in main
    debug=options.debug)
  File "/home/john/gnuradio/ionosonde/src/python/ionosonde.py", line 179, in __init__
    verbose=self._verbose)
  File "/home/john/gnuradio/ionosonde/src/python/ionosonde.py", line 56, in __init__
    self._u = usrp.sink_s(fpga_filename="ionosonde_tx_test0106.rbf")
  File "/usr/local/lib/python2.5/site-packages/gnuradio/usrp/usrp_swig.py", line 2736, in sink_s
    return _usrp_swig.sink_s(*args, **kwargs)
RuntimeError: can't open usrp
