After several updates, an error message appears saying, “/boot/dpt-“ cannot be found. This is setting up ee-prom for the RPI3B+. Multiple updates and every one says error/failed update.
The folder, /boot/dpt-1, exists. “/boot/dpt-“ does not. This looks like a syntax error in an update script. Either the number after the hyphen is ignored, or, the script left a section out to determine the appropriate folder to copy data.
