Ok. below is what I have observed. When I run the above mentioned GRC file
(containing two flowgraphs), I get below error:
AttributeError: 'gr_top_block_sptr' object has no attribute
'my_custom_block_1_0'
When I open the corresponding top_block.py file, I can see that the definition
of function probe comes before the definition of 'my_custom_block_1. So, when I
put the definition/instantiation of 'my_custom_block_1 before the definition of
function probe, I don't get any error. Why GRC is generating the code in this
manner? It should rather instantiate the DSP blocks first and then the
variables/function probes etc.
Thanks,
Yu.
