Hi Ric2,


Probably I will need some time to consult the team again to have a better understanding referring to your latest questions.


Anyway, from the current information which I have. Referring to the this document which touch on the Avalon Steaming Sideband Signals:

"https://www.intel.com/content/www/us/en/docs/oneapi-fpga-add-on/developer-guide/2024-0/host-pipes-rtl-interfaces.html"


There is a statement which says "You must set use_empty for all packet interfaces that carry more than one symbol of data that have a variable length packet format." following with some example of StreamingBeatstruct to be set for your reference.


Thanks.

Regards,
