Re: [Discuss-gnuradio] Filter output float to complex

[Sakthivel Velumani]

Hi,

Please find the code here https://github.com/saki92/oqpsk-sync-block . I am trying to build a clock sync block for oqpsk with pfb_clock_sync as reference.

It does not show any error message from Python or C++. The flowgraph runs for less than a second and stops. Some times I get a return code -11.

Best regards,

Sakthivel

Hi Sakthivel,

this will be impossible to answer without you sharing your code,
instead of just this pseudocode, alongside with the actual meaning of
"it crashes". Does it segfault without a message? does it give a python
error? A C++ exception?

Best regards,
Marcus
