Roon Bridge on an Asus Tinkerboard

Hi again Steve. I am just about ready to buy a Tinkerboard S based on our discussions so that I can install Roon bridge on it. I do have a concern though in that a couple of people on my site have raised concerns about running the installation, i.e. Karl-Heinz Fink and Jerry_B. Have you heard of any problems in that area?

Also, do you have any instructions as to how I would go about installing the DietPi OS onto the permanently installed Tinkerboard S emmc card instead of the removable micro SD card. The emmc card is supposed to be faster.
Thanks Steve,
Bill
