[Discuss-gnuradio] Hierarchical Blocks

[abbasi9999]

Hi all,

According to the tutorial of Gnu radio / python applications, It is possible
to create Hierarchical blocks. However when i try to implement it i get some
errors. is it possible to trace the flow graph while its is running to check
where the error is ? how? / OR is my using of connect method is wrong?

This is my connecting code:
##########################################################################
At original class:
self._u is an object of my usrp (which initiated to have 2 channels)

    gr.hier_block2.__init__(self, "generic",
            gr.io_signature(0, 0, 0), # Input signature
            gr.io_signature(2, 2, gr.sizeof_gr_complex)) # Output signature
    .......................
    self.connect(self._u, self.di)
    self.connect((self.di,0),(self,0))
    self.connect((self.di,1),(self,1))

In my top_block class:

"self.sense_u" is an object of the previous "self"
    self.rxpath.connect((self.sense_u,0), self.rxpath.block0a)
    self.sense_tb.connect((self.sense_u,1), self.sense_tb.block1a,
self.sense_tb.block1b, self.sense_tb.block1c, self.sense_tb.block1d)

##########################################################################
The error: 
terminate called after throwing an instance of 'std::invalid_argument'
  what():  destination already in use by edge
usrp_source_c(32):0->deinterleave(33):0
Aborted

thanks
