Hello Kirsten,
I remember getting the same error message while developing a custom
RFNoC block. I found the problem to be caused by the corresponding xml
file which is located in the grc folder. I am not sure what part of the
file exactly caused the error message (maybe the ordering of the
parameters or tags within the parameters) but I eventually solved it by
replacing the file with the xml file from a working block and modifying
that one.
Best regards,
Lars

Hello,
I am using a USRP X310 and am using gnuradio companion to test a
custom block. The current diagram flows as follows: File Source->RFNoC
FIFO->custom block->complex to image->frequency sink. However, when I
try to execute, I get the error ‘timeout on chan 0’. My testbench
passes all 5 cases; I can read signals on the inputs and outputs of
the noc block and the flow graph works once I remove my custom block.
Where else should I be looking?
Thanks,
Kirsten
