Upgrade information

• Upgrading from EWA90
  It is not possible to load a project created with EWA90 in EWAVR. There is currently no automated tool available to convert an EWA90 project into an EWAVR project. See also the guide Migrating from EWA90 to EWAVR.

• Upgrading from version 2.27B
  An invisible command is sent to the IAR XLINK Linker when a specific derivative is chosen. For example, when the derivative ATmega128 is chosen, in General->Target->Processor configuration , the files cfgm128.xcl and cfg3s.xcl are sent to XLINK.
  In previous versions of EWAVR up to V2.27B, cfg3s.xcl or a corresponding file was still sent to XLINK even though the XLINK->Include->XCL file name->Override default option was selected.

  This has now been corrected. Now when the XLINK->Include->XCL file name->Override default option is selected, only the chosen *.xcl file is sent to XLINK. If you want the same behavior as in the older version, a simple way is to type this command line -f $TOOLKIT_DIR$\src\template\cfg3s.xcl into the XLINK->Extra Options box, another way is to add -f cfg3s.xcl in your *.xcl file.

New features

New devices
Support has been added for the following devices:
ATtiny840, and ATtiny102.

Known Problems

• EW25753: The first time a project is built with both multi-file compilation and parallel build enabled, no out file is generated.

• EW24321: If you edit and add lines after the visible line of a collapsed region in the editor, it looks as if the region expands but it does not. You must collapse and expand the region to see all of your text again.

• EW22885: If you install in another location than the default location, the installer always adds IAR Systems to the menu path.

• EW22592: In some cases the Find in Files window fails to display Japanese characters (e.g. in comments) properly.

• EW19935, EW19927: Paths to files specified in the Tools>Options>Linker>Extra options dialog box cannot contain spaces.

• EW19451: Sometimes Find in Files can fail to read a file because of a sharing violation.

• EW19023: IAR Embedded Workbench does not correctly handle paths containing dollar sign characters ($).

• EW18879: Control V and Control C does not work in the online help system.

• EW18256: If more than one IAR Embedded Workbench for AVR application is running at the same time, the Tools>Options dialog box is incorrectly displayed in the second application.

• EW18107: Replacing an existing shortcut with exactly the same one in the Tools>Options>Key Bindings dialog box will cause a Runtime Error.

• EW17201: An auto indent of the entire source line will occur if the character '#' is used in a comment at the end of the source line.

• EW17097: If the Auto indent feature is enabled, a ':' in a comment is interpreted as a label and indented accordingly.

• EW16800: The IAR Embedded Workbench IDE can become unstable when the argument variable $TARGET_xxx$ is used to define output directories on the Options>General Options>Output directories page. As a workaround, use $PROJ_DIR$\Debug\Exe or $PROJ_DIR$\Release\Exe instead of $TARGET_DIR$.

• EW11881, AVREW0041: The IAR Embedded Workbench IDE allows you to select two different fill patterns for unused memory; XLINK general fill and INTVEC RETI fill. However, with XLINK you can only define on fill pattern.

V2.26B - 2001-07-06

Program corrections

• AVREW0026: When configuring via dialog boxes, deselecting the option 'Initialize unused interrupt vectors with RETI instruction' had no effect, it was always on.

• AVREW0025: The Library configuration tab was disabled when using -v options to specify target processor.

• AVRW0002: Switching between the IAR CLIB library and the C/EC++ libraries did not change the include path of the assembler. This caused the assembler to always access the C/EC++ library includes, instead of the IAR CLIB includes. This was only an issue when using C include files in an assembler file (e.g. ctype.s90).

V2.25E - 2001-05-04

Program corrections

• AVRG0020: The utility postlink.exe was never installed.

• AVREW0000: It was not possible to start the C-SPY ROM-monitor from within the IAR Embedded Workbench. The dialog boxes to set the communication parameters were disabled, as it is not possible to select any other driver than Simulator.

V2.25B - 2000-10-31

Program corrections

• The initial state of the "Place string literals and constants in initialized RAM" option on the "Code Generation" page of the Compiler options category has been changed from default off to default on.

  This is the appropriate setting for all projects that do not have external ROM connected to the system using the external data bus.

V2.25A - 2000-09-01 [Pre-release]

First public release.

Program corrections

• The options available on the "Library Configuration" and "System Configuration" pages are in most cases all that need to be changed when setting up a new project. You no longer need to manually change the linker command files in order to set up these parameters.

  To use the system configuration tabs, make sure that you have selected a specific processor derivative under the "Processor Option" options. It is not possible to use the system configuration tabs when using the generic processor options (-v0 ... -v6 ).

  To disable the system configuration tabs, simply deselect the "Configure system using dialogs (not in .xcl file)" checkbox.

  The options under these two new tabs allow you to control the size of the stacks, as well as the size of the heap. The heap is used when dynamically allocating memory with malloc, realloc, calloc, and new . You do not need to set this value to zero if you do not use dynamic memory allocation, as the system will automatically detect this and remove the heap segment.

  The new configuration tabs also allow you to control where the stacks are placed, as well as which library to use. Please note that the IAR Systems CLIB Clibrary does not support Embedded C++. For those target microcontrollers that may have external memory, the "System Configuration" page gives an easy way to add segment definitions for a single area of external SRAM, ROM, or EEPROM.

• Selecting the check-box "Enable bit definitions in IO-Include files" on the "Library Configuration" page in the General category of the Project options dialog box will result in an extra parameter being passed to the compiler:

        -DENABLE_BIT_DEFINITIONS

  This preprocessor define will enable the section in the I/O include files that defines the bit names of many of the registers in the specified AVR microcontroller.

V2.21H - 2000-07-21 [Pre-release]

Program corrections

• New configuration dialog boxes added.

V2.20C - 1999-10-01 [Non-public release]

Program corrections

• None
