3.11 Firmware Update There are two ways to update the firmware of the AT85DVK-07 board.
• Using the automatic firmware update feature
• Using the explorer application
Note: The update feature is a safe procedure: in case of accidental power failure, the player will
resume the firmware update on the next power-up.
3.11.1 Automatic Firmware
Update
At each power-up, the system checks if an update file is present in the “C:\Update”
directory of the Nand Flash disk. If a file “Player_dvk.atm” is found, the firmware update
starts:
The update file is copied in its update location using the mass-storage operating mode.
Notes: 1. The update directory location (directory or disk) as well as update file name can be
easily modified at compile time by configuring the conf_update.h file.
2. The update file is deleted at the end of the update.
3.11.2 Manual Firmware
Update
Launch the Explorer application. Navigate to a .atm file into any disk but USB keys in
host mode and execute it by pressing the Select key. The firmware update starts.
