`Collect a prebuilt board-agnostic root filesystem tarball and a prebuilt PYNQ source distribution. Starting in PYNQ v3.0, by default the SD card build flow expects a prebuilt root filesystem and a PYNQ source distribution to speedup and simplify user rebuilds of SD card images. These binaries can be found at [the PYNQ boards page](http://www.pynq.io/board.html/) and copied into the sdbuild prebuilt folder` I could only find the rootfs’s in the pynq boards page ---

Hi there, You should be able to download the sdists from the boards page now. Also, you can always download the sdist tarballs for most recent PYNQ versions from the github repo itself [https://github.com/Xilinx/PYNQ/releases/download/v3.0.0/pynq-3.0.0.tar.gz](https://github.com/Xilinx/PYNQ/releases/download/v3.0.0/pynq-3.0.0.tar.gz) Thanks Shawn ---
