I understand that we can choose Ubuntu 16.04 or 18.04 to build the PYNQ image. However, aren’t we limited with what version PetaLinux 's supported OS. For an example, I used a Ubuntu 18.04, and installed PetaLinux 2018.3, but this version of PetaLinux is only supported by Ubuntu 16.04. The way I know this is by checking it’s documentation.
Does this mean, that I have to use Ubuntu 16.04 version if I want to use a Xilinx tools version of 2018.3?
