And have used it to successfully build the project, including with modificatons described to create a SD based system with full development system based on a Ubuntu userland.
There is only one mystery I have so far never solved - the file package includes a bitstream in images/linux/system_wrapper.bit which is included in all the example "petalinux-package" commands, but I have no idea where this bitstream came from or what functionality it might define. I assume that the '--fpga' argument can be omitted if no bitstream is required, so I have assumed this must be being included for a reason. When booting the Petalinux image from SD, I don't see any of the LED activity that is visible when running Q-SPI based demo.
Can anyone elaborate on what the story is behind this bitstream? Can I safely replace it with something else? Or just omit it completely?

I have gone through the Digilent Zybo Z7-20 Petalinux BSP Project here:
