Hi @DaveCuroe ...... I had the same issue, followed the directions as per this Forum and ended up with a high pitched trilling beep.....
To FIX it, first I made sure there were NO other BIN files in the root directory of the MicroSD card, then I reloaded the file =
Ender-5 Pro- Marlin2.0.1 - V1.0.1 - Endstop.bin

After rebooting the machine fired up.... TMC error disappeared and the beeping vanished.

Now to find out how to invoke this Silent Upgrade they promised.

That said, if this is what they call SILENT running, I am not sure I would agree..... this is like sitting in a server room.
