Debug sessions on debugWIRE target devices are clocked by the target device itself, and thus no
frequency setting is required. The Atmel-ICE will automatically select the correct baud rate for
communicating at the start of a debug session. However, if you are experiencing reliability problems
related to a noisy debug environment, some tools offer the possibility to force the debugWIRE speed to a
fraction of its "recommended" setting.
Debug sessions on AVR XMEGA target devices can be clocked at up to the maximum speed of the
device itself (usually 32MHz).
Debug sessions on AVR UC3 target devices over the JTAG interface can be clocked at up to the
maximum speed of the device itself (limited to 33MHz). However, the optimal frequency will be slightly
below the current SAB clock on the target device.
Debug sessions on UC3 target devices over the aWire interface will be automatically tuned to the optimal
baud rate by the Atmel-ICE itself. However, if you are experiencing reliability problems related to a noisy
debug environment, some tools offer the possibility to force the aWire speed below a configurable limit.
Debug sessions on SAM target devices over the SWD interface can be clocked at up to ten times the
CPU clock (but limited to 2MHz max.)
Preserve EEPROM
Select this option to avoid erasing the EEPROM during reprogramming of the target before a debug
session.
Use external reset
If your target application disables the JTAG interface, the external reset must be pulled low during
programming. Selecting this option avoids repeatedly being asked whether to use the external reset.
6.2. Command Line Utility
Atmel Studio comes with a command line utility called atprogram that can be used to program targets
using the Atmel-ICE. During the Atmel Studio installation a shortcut called "Atmel Studio 7.0. Command
Prompt" were created in the Atmel folder on the Start menu. By double clicking this shortcut a command
prompt will be opened and programming commands can be entered. The command line utility is installed
in the Atmel Studio installation path in the folder Atmel/Atmel Studio 7.0/atbackend/.
To get more help on the command line utility type the command:
atprogram --help
