Important information

• IAR FIT Module Importer Tool removed
  The graphical tool for importing FIT (Firmware Integration Technology) modules into an IAR Embedded Workbench project has been removed together with the IAR FIT modules. It is no longer needed as the FIT modules that comes with Renesas Smart Configurator V2.2.1 (and newer) are compatible with IAR Embedded Workbench.

New features

• RX72N and RX66N supported
  The RX72N and RX66N groups of microcontrollers are now supported.

Known Problems

• [EWRX-582], [IDE-4328] The built-in editor may have problems when there are multiple monitors where each has a different DPI setting. This is possible in Windows 10 where you can set different scales.

• IAR Embedded Workbench IDE - Known problems

Release history

4.13.1 2019-11-20

New features

• RX72M, RX13T and RX23W supported
  The RX13T and RX23W groups of microcontrollers as well as the RX72M group, including the new double-precision floating-point processing instructions, are now supported.

• Renesas Smart Configurator fully supported
  With Renesas Smart Configurator V2.3.0 (included), the FIT (Firmware Integration Technology) modules are now compatible with IAR Embedded Workbench. This means that the tool supports the following three functions related to embedding Renesas drivers in your systems: importing middleware, generating driver code, and generating code for making pin settings. The generated modules are incorporated via the IAR Project Connection mechanism.

• RX DSP Library Version 5.0
  An application example using Renesas RX DSP Library Version 5.0 has been added.

4.12.1 2019-06-18

4.11.1 2019-02-18

4.10.2 2018-11-28

Program corrections

• [EWRX-567, TPB-3059] When generating output in the Motorola-s-records output format, ielftool can produce a spurious record in the following circumstances:

  • the executable ELF-file contains two contiguous segments (this more or less requires the generation of filler bytes, the linker will normally merge contiguous content to a single segment)
  • the second segment was small enough to not break the current s-record row (an s-record row generated by ielftool can contain no more than 16 bytes)
  • the second segment was not contiguous with another, third, segment

  In these cases the address of the spurious record will be offset by the number of payload bytes in the record. If address was supposed to be 0x8040 and the record would contain 6 bytes the address will be 0x8046. The bytes will be correct but the address will not. The file will contain a gap where the bytes were supposed to go.

C-STAT features innovative static analysis that can detect defects, bugs, and security vulnerabilities as defined by CERT and the Common Weakness Enumeration, as well as help keeping code compliant to coding standards like MISRA C:2012/2004 or MISRA C++:2008. For more information, see the C-STAT Static Analysis Guide.

• Renesas AP4 for RX included
  Renesas AP4 (former Applilet) is a standalone tool for automatically generating control programs (device driver programs) for peripheral modules in accordance with settings. It fully supports code generation for IAR Embedded Workbench for RX and the generated modules are incorparated via the IAR Project Connection mechanism.
• Renesas Firmware Integration Technology (FIT)
  Firmware Integration Technology (FIT) is a Renesas concept that emphasizes the simplification of embedding of peripheral function module drivers and improvement of portability between RX microcontrollers. A selection of these FIT modules are now included in the Information Center under Example projects.

It is easier to administer and a new single CD concept enables all variants of IAR Embedded Workbench for a certain product to be included in one and the same installer.

2.30.5 2012-02-16

Program corrections

• [EW22829] In the RDKRX62N and RPBRX62N example code, the code construction #ifdef __LITTLE_ENDIAN__ was used. This does not work as __LITTLE_ENDIAN__ is defined either as 0 or 1. This has now been changed to #if __LITTLE_ENDIAN__.
