The order of power up
execution allows the
MP3 Audio Machine to
use the removable drive
to update itself, either
temporarily or
permanently.
When power is first applied to the MP3 Audio Machine, it flashes the front panel
LED green while performing a self test. It then checks to see if a track or Play List
should be played, according to the following priority:
•
If the test button is depressed, check for FIRMWARE.BIN on Compact Flash
card. If it is found, update firmware and automatically reboot.
•
If the test button is depressed, process command file COMMAND0.BAT on the
removable media. Currently no functionality is associated in the unit with
command files. This functionality is reserved for future development.
•
Play any track or Play List that is hardwired at the Control Connector.
•
Play track or Play List 0 from the media
The first condition detected will be processed. Successive conditions are ignored. If
more than one file has the same number, the first file found will be used.
