It definitely works on an Ubuntu 18.04 distro, it just seems to be a 
problem with your SoC.

Have you read this: 

And this: https://wiki.samba.org/index.php/File_System_Support

I can assure that it works on ARM,well it does on my Rpi4, problem is, 
you seem to be using a niche product.

Where is your github page, I couldn't find it with a google search.
