Release history

4.21.3 - Service Pack 2 - 2014-09-01

Program corrections

• EW24605
  The Overwrite old data option isn't available in the Trace settings dialog box.

4.21.2 - Service Pack 1 - 2014-07-09

Program corrections

• An issue with parsing device configuration data can cause the debugger to use incorrect flash controller addresses on some devices. This results in failed downloads and incorrect fuse handling.

• EW24003
  Trace buffer overrun protection together with data trace write might lock the target in a non-OCD mode when using NanoTrace. Deselect one of the options Transmit queue>Enable overrun protection or Trace data>Enable data trace (write) in the Trace Settings dialog box if you experience this problem.

4.21.1 - 2014-05-28

New features

• Attach to running target
  It is possible to attach the JTAGICE3 debug probe to a running target without resetting the target. The JTAGICE3 Setup page now contains the additional option Attach to running target. This option must be disabled when you download the application for the first time. You can then end the debug session, select the option, and attach to your running target. This feature is not applicable on all devices.
  

• Atmel-ICE support
  The AVR JTAGICE3 driver now supports the Atmel-ICE debug probe and the Atmel Embedded Debugger (EDBG) interface.
  

4.20.2 - 2013-08-28

Program corrections

• EW24130
  Live watch and live memory may trigger unaligned read operations which in turn will cause the communication with the emulator to become unsynchronized.

4.20.1 - 2013-07-05

Program corrections

• EW23942
  Using a JTAG daisy chain now works.

• EW23267
  The JTAGICE3 driver no longer times out when using aWire to connect to some UC3 devices.

• EW23248
  Download speed when using aWire can now be improved through the use of a "Device Support Module". Please see the on-line documentation for more information concerning this feature.

• EW23103
  A threading issue has been corrected. C-SPY no longer crashes if several watch (variable) windows are open at the same time.

• EW22376
  The device ID value for UC3B1128 has been corrected.

• EW21383
  The diagnostic message issued when Verify Download fails is unclear and can be misleading.

4.10.12 - 2012-06-04

Program corrections

• EW23241
  The emulator driver certifies that the Vdd voltage is above a given threshold level before allowing a debug session to start. The threshold level was previously set to 1.8 V, but as many AVR32 device specifications allow for a Vdd level as low as 1.62 V, the threshold level has been adjusted downwards to 1.55 V.

4.10.10 - 2012-03-06

Program corrections

• EW22947
  The C-SPY emulator driver no longer corrupts status register flags when you debug with interrupts enabled (with the GM bit in the Status Register set to zero).

4.10.9 - 2012-02-29

Program corrections

• EW23017
  C-SPY drivers and the processor module no longer fails to correctly parse the --cpu_info command line option when the path is given as a separate option.

4.10.7 - 2012-02-08

• None

4.10.1 - 2011-06-28

New features

• JTAGICE3 support
  Support for the JTAGICE3 In-System debug probe has been added to the product. Both debugging over JTAG and aWire is supported when using JTAGICE3.
