- Source: ERIKA Enterprise
ERIKA Enterprise is a real-time operating system (RTOS) kernel for embedded systems, which is OSEK/VDX certified. It is free and open source software released under a GNU General Public License (GPL). The RTOS also includes RT-Druid, an integrated development environment (IDE) based on Eclipse.
ERIKA Enterprise implements various conformance classes, including the standard OSEK/VDX conformance classes BCC1, BCC2, ECC1, ECC2, CCCA, and CCCB. Also, ERIKA provides other custom conformance classes named FP (fixed priority), EDF (earliest deadline first scheduling), and FRSH (an implementation of resource reservation protocols).
Due to the collaboration with the Tool & Methodologies team of Magneti Marelli Powertrain & Electronics, the automotive kernel (BCC1, BCC2, ECC1, ECC2, multicore, memory protection, and kernel fixed priority with Diab 5.5.1 compiler) is MISRA C 2004 compliant using FlexeLint 9.00h under the configuration suggested by Magneti Marelli.
In August 2012 ERIKA Enterprise officially received the OSEK/VDX certification; see below.
History
ERIKA Enterprise began in the year 2000 with the aim to support multicore devices for the automotive markets.
The main milestones are:
2000: support for STMicroelectronics ST10
2001: support for ARM7
2002: support for Janus, a prototype dual ARM7 system for the automotive market
2004: support for Hitachi H8
2005: support for Altera Nios II, with support for partitioning on multicore designs; availability of the RT-Druid code generator
2006: support for Microchip dsPIC
2007: support for Atmel AVR Micaz
2009: announced ERIKA website on TuxFamily
2010: support for TriCore, Freescale S12XS, Freescale PowerPC 5000 PPC MPC5674F Mamba, Microchip PIC24, Microchip PIC32, Lattice MICO32, eSi-RISC
2011: support for Texas Instruments MSP430, Renesas R2xx, Freescale S12G, Freescale PowerPC 5000 PPC MPC5668G Fado
2012: support for ARM Cortex-M, Atmel AVR (Arduino), TI Stellaris Cortex M4, Freescale PowerPC 5000 PPC MPC5643L Leopard, NXP LPCXpresso. ERIKA Enterprise received OSEK/VDX certification.
2013: ERIKA Enterprise is supported by E4Coder automatic code generation tool.
2014: OSEK/VDX certification for Tricore AURIX
2017: RTOS was rewritten from scratch; new version (3) has proper support for multicore platforms (i.e., one binary for multiple cores), better support for memory protection, and an easier build system. The source code is now maintained on a GitHub repository.
2017: ERIKA v2.8.0 is released in November 2017.
2018: Multicore and AUTOSAR Scalability Class 1 added to ERIKA3. Graphical editor now available for the OIL file.
2019: On May 24, Erika released version RH65. Since August 27, 2019, the official website of ERIKA has not been updated up to the present date of April 2, 2024.
Licensing
Version 2 of the RTOS was released under GPL linking exception. Version 3 of the RTOS (also called ERIKA3) is released under plain GNU General Public License (GPL), with the linking exception sold on request.
Industrial usage
In 2010, Cobra Automotive Technology announced support for ERIKA Enterprise
In 2010, EnSilica and Pebble Bay consultancy ported ERIKA Enterprise to a family of configurable soft processor cores for automotive systems
