ERIKA Enterprise is an open-source and royalty-free OSEK/VDX Kernel. This RTOS includes also RT-Druid, which is a development environment distributed as a set of Eclipse plugins.
ERIKA Enterprise implements various conformance classes, including the standard OSEK/VDXconformance classes BCC1, BCC2, ECC1, ECC2, CCCA, CCCB. Moreover, ERIKA provides other custom conformance classes named FP (Fixed priority), EDF (Earliest deadline first scheduling), and FRSH (an implementation of resource reservation protocols).
Thanks 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 received officially the OSEK/VDX Certification (see below).
ERIKA Enterprise started in 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 ARM 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 Nios II 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, Ensilica 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.
