Arduino uno with sparkfun mp3 player shield.
Everything fine but after 18hours the system stops functionning. Unable to play MP3 files.
Error coded 4 during SFEMP3Shield::begin().
Error code 4 = Other than default values were found in the SCI_MODE register.
SFEMP3Shield::end() does no resolve the problem. Even reset does not.
Only power down allows sytem to run again.
Any help appreciated...
