Also, there is a timeout clock running somewhere (can't recall off the top of my head) that will throw that message when it gets tripped. That is fine though if you are INTENDING to do something that might cause there to be a gap in samples and trigger a timeout. I had an RFNoC block that was taking chunks of data and throwing away samples until a condition was met. That message was printed because it didn't see samples moving though the stream, but that was by design. I am almost positive that when having this discussion on the mailing-list in the past, someone pointed out where they commented out the line in UHD since they were doing something similar and didn't want to see it.

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.

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?
