But the question list is still missing 1 part can or cannot the current version API support overlay is going to reload wo AXI-Stream interface or even non-AXI related interface (custom interface only)?
If so I guess this is just a DFX wrapper on python which just helping out Xilinx a bit to improve the user control level.
reload wo AXI-Stream interface
Does “wo” mean without?
If I understand the question, the AXI stream switch is a key component of the current composable overlay. Static IP and DFX regions are connected to the switch and the rest of the design via AXI interfaces. The API is built to support this.
It would be possible to build your own design with custom interfaces, but if you want to connect them yourself you would need to build your own interconnect. If you want to reconfigure the design like the Composable overlay, you would need to extend the API to support the same level of functionality.
