10.1 What's New in Major Version 3
Firmware version 3 adds SAM support
When installing Atmel Studio 6.1 SP2, the JTAGICE3 will receive a major firmware increment from version 2 to version 3. While version 2 firmware enumerates as a Jungo USB tool in the device manager, version 3 appears as a HID device (with a new USB PID), much like the EDBG included in Xplained Pro series of evaluation kits.
The new JTAGICE3 firmware brings support for all Atmel SAM ARM Cortex-M based microcontrollers to the JTAGICE3, while preserving all of the AVR functionality.
As of version 3.11, the JTAGICE3 also supports serial ITM trace capture.
After upgrading to firmware version 3, the JTAGICE3 will NOT be recognized by previous versions of Atmel Studio. In order to use the JTAGICE3 with an older version of Atmel Studio, it must first be downgraded back to version 2 firmware.
The atfw.exe command-line firmware upgrade utility
must be used with the -a archive-name switch to give the utility the
path to the version 2 firmware zip file. After the downgrade, older versions of Atmel
Studio will work as expected.
The atfw.exe command-line upgrade utility can be downloaded from the Atmel website or from the Atmel Gallery. The Atmel Gallery download contains atfw.exe and the needed firmware version.
