Hi Dario,
Interesting. I would expect 2 UBX-160 with 2 radio blocks into the 2 input
ports to work. My best guess is that there is some issue with either the
detected upstream nodes or the propagation of the stream command. It would
be interesting to debug the
Hi Mike,
Unfortunately it must be more widespread as I am using 2 ubx160 and connecting
2 rfnoc radio blocks to the two inputs of my single block.
If you look in the history of the last few weeks you will see that I asked for
help without really getting a final answer and after some debugging I
Hi Dario,
OK. I dug in a bit more and I can now tell you are most likely using the 2
streams from a single TwinRX daughterboard by the nature of the issue. The
root cause is that Twin RX uses ports 0 and 1 on the radio block (all other
daughterboards only use port 0) and only port 0 is
Hi Mike,
Unfortunately what you write is not what I see. Split stream has 1 input and 2
outputs and that works. What I am saying is that the opposite doesn't. This
seems to be due to the fact that for some reason blocks feeding second input
are not started if block does not have a second port.
Hi Dario,
A block can have any number of inputs and outputs, so 2 inputs and 1 output
is fine. The Split Stream block is an example of an asymmetric block.
The UHD XML description of the Split Stream block can be found here:
Hi,
I am still struggling with a block which should have 2 inputs and 1 output.
Apparently everything is fine with both FPGA and software but the second input
is not fed with data.
I could not find any example of an asymmetric block with different number of
inputs/outputs so I am starting to
