I am implementing the "Transmit and Receivea a Tone Using Xilinx RFSoC Device- Part I and II" from MATLAB/SIMULINK.

The model simulates perfectly. Infact, I reach the last stage of capturing the data. But, at the last stage of capturing the data at the ADC, I get the following error message:
"Unable to send message from 'Output Port 1' of block 'soc_rfsoc_datacapture_sw?IODataSource_Stream/Variant/SIM/Source_Variant/From_Constant/HWSW_Message_Send/Message_Send' because the output port is blocked. 2 messages were dropped during this simulation. To prevent messages from being dropped, increase the capacity of message storage connceted to this output port".
I am using the Xilinx ZCU111 evaluation board and MATLAB R2021b.
Any help and suggestions would be highly appreciated.
Thank you.

Hi Kefayet,
The error indicates that the output port of “soc_rfsoc_datacapture_sw?IODataSource_Stream” is blocked, causing messages to be dropped.
To fix this I would suggest you do the following:
  1. Ensure that the message storage capacity is sufficient for the output port and increase the message storage capacity for 'Output Port 1' if needed.
  2. Ensure proper configuration of the connected message storage block. This should prevent message loss during simulation with your Xilinx ZCU111 board and MATLAB R2021b.
  3. Check if the message storage block is connected to the correct input port.
This should fix data capture issue`.
