Hi, Actually I managed to find a suitable block, Stream to Vec Decim under [Sream Operators]. Now it generates fine but I get the following runtime error:
Traceback (most recent call last): File "/home/nikos/Desktop/top_block.py", line 143, in <module> main() File "/home/nikos/Desktop/top_block.py", line 131, in main tb = top_block_cls() File "/home/nikos/Desktop/top_block.py", line 78, in __init__ self.device3, File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 92, in __getattr__ return getattr(self._impl, name) AttributeError: 'top_block_sptr' object has no attribute 'device3' Got bus address: "unix:abstract=/tmp/dbus-HUCB3jtUxk,guid=cee5aa19c0d99081aead7b3256e24e66" Connected to accessibility bus at: "unix:abstract=/tmp/dbus-HUCB3jtUxk,guid=cee5aa19c0d99081aead7b3256e24e66" Registered DEC: true >>> Done (return code -11) Seems device3 is needed by the RFNoC fosphor fft generator. How can I fix that? Attached are top_block.py, and fosphor.grc flow.
