Pynq Z2 Petalinux boot and serial?

hi, I’m on your same boat, I am tasked to use the pynq z2 board to create a custom ip connected through the axi interface and use a device driver to access it. However I cannot find the bsp for the board. I built the base board .xsa and build a bsp from petalinux but it doesn’t work. I can’t seem to understand what other files need to be included in the petalinux bsp project to make it work.
