IAR Embedded Workbench for Renesas RL78 version 4.21.4

IAR Systems, the future-proof supplier of software tools and services for embedded development, is pleased to announce the availability of IAR Embedded Workbench for Renesas RL78 version 4.21.4 is the complete development toolchain to create smaller, faster, smarter code for all RL78 devices.
Release notes for IAR Embedded Workbench for Renesas RL78 version 4.21.4
Known problems
[EWRL78-794] In some cases the installer for an IAR Embedded Workbench Service Pack (SP) displays an error message stating that there is no previous version of the product installed, even when a previous version actually is installed. This misleading message is displayed when the existing version is too old to be updated by the Service Pack installer, for example, when EWXX v1.10 is installed and you try to apply EWXX SP v1.30.2.
Program corrections
[EWRL78-894] The reserved area 0xE6 to 0x131 is incorrect in the RL78/F24 linker configuration files (.icf) and the start address of the ROM memory should be 0x132.
[EWRL78-903] The E1 and E20 emulators are not able to update their firmware due to missing files in the product installation. This leads to a crash in the debugger driv
User guide corrections
[EWRL78-856] All data _init sections have incorrect placement descriptions in the IAR C/C++ Development Guide (repeating the placement descriptions for the corresponding data section). The correct placement for data _init sections is: "This section can be placed anywhere in ROM memory."
RAM Start Setting Register handling (RAMSAR)
The system startup code (cstartup.s) allows setting up the RAM Start Setting Register (RAMSAR) available for some microcontroller groups, dynamically via a linker defined symbol. By default, this symbol (_RAMSAR_ADDR) defined in the linker configuration file (.icf), is set to enable the whole RAM area.

IAR Embedded Workbenchdelivers a complete development toolchain for building and debugging embedded applications for your selected target microcontroller. The included IAR C/C++ Compiler generates highly optimized code for your application, and the C-SPY Debugger is a fully integrated debugger for source and disassembly level debugging with support for complex code and data breakpoints.
With more than 4,000 supported Renesas devices, IAR Embedded Workbench supplies exceptional design flexibility for embedded developers working with the extensive Renesas product portfolio. The tools deliver outstanding performance and let our customers migrate easily between different architectures, and choose the one best suited for a specific application while using the same development tools. It also simplifies reuse of code.
Renesas RL788/16-bit microcontrollers (MCUs) greatly improve power efficiency with industry-leading low power consumption at 41μA/MHz consumption during normal operation and 0.355μA during clock operation. Built-in features such as a high-precision (±1%) high-speed on-chip oscillator, background operation data flash capable of 1 million rewrites, temperature sensor, and interface ports for multiple power supplies help reduce system costs and size.
