no /dev/xlnk in prebuilt linux image

Hey y'all,

For my current project, I'm using the zcu102 board.

I downloaded the prebuilt ubuntu image from this link:

I've tried to interact with the FPGA, but when I try to, I find that my syscall trace reveals an issue: 

openat(AT_FDCWD, "/dev/xlnk", O_RDWR)   = -1 ENOENT (No such file or directory)

As you would imagine, /dev/xlnk does not exist



This image fits my needs in many ways, as I can use a package manager for downloading the tools I need (namely keras). However, I have run across the issue that the xlnk driver for this image doesn't appear to exist. I understand that I could create my own petalinux image, although I'd like to avoid that.

I see that there is a directory that exists: 


I can't really figure out if interacting with this directory can create the xlnk device driver

Does anyone had similar troubles? I figure I could build xlnk.ko and insmod it, but it seems like an awful lot of work, given the limited support for this on the zcu102 board.
