Hi Josh,
I've changed the .xml file. Also, I've checked the new top_block.py file
and it is generated as follows:
self.extras_uhd_amsg_source_0 =
gr_extras.uhd_amsg_source(uhd.device_addr="172.17.3.140"
However, it is still complaining when I run the flow graph:
File "/home/asrpuser/Desktop/Jose Torres Material /top_block.py", line 33
self.extras_uhd_amsg_source_0 =
gr_extras.uhd_amsg_source(uhd.device_addr="add=172.17.3.140")
SyntaxError: keyword can't be an expression
Thanks,
Jose.
