Hi,

I do not fully understand your question.  
What flag and config is this?

Do you want to install the `pynq_composable` package when you are building the SD Card image?

When the SD Card Image is build there are several flags we can set AKA  
stage4\_package = xrt pynq …  
So as my original question proposed any flag we can set to include composable.  
if package pynq is not set in the stage4\_package what will happend just simply applied to my first question.

Thank you

No, there’s no `pynq_composable` package for stage4.

However, you can create your own package. For the composable, it will be something similar to this [PYNQ/qemu.sh at master · Xilinx/PYNQ · GitHub](https://github.com/Xilinx/PYNQ/blob/master/sdbuild/packages/pynq_peripherals/qemu.sh)

But, instead of `pip install` directly, you should use this instructions [GitHub - Xilinx/PYNQ\_Composable\_Pipeline: PYNQ Composabe Overlays](https://github.com/Xilinx/PYNQ_Composable_Pipeline#install-composable-pipeline-on-your-board)

@marioruiz

Understood, but just a small question why not including or even default installed on the latest PYNQ 3.0.1 as this is what PYNQ team trying to sell us Composable Overlay is powerful and flexible on most pipelined acceleration applications?
