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.


ERIKA Enterprise began in the year 2000 with the aim to support multicore devices for the automotive markets. The main milestones are:


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.[8]

Industrial usage

Hardware support

The ERIKA Enterprise kernel directly supports:

Other evaluation boards are supported.[16]
