ARM Cortex MX support
ERIKA Enterprise supports ARM Cortex MX microcontrollers.
The support for RT-Druid is now available.
The Cortex M0 support includes:
- support for IAR compiler;
- support for single and multi stack configurations;
- ISR interrupt supported;
- support for IAR J-Link Debugger.
The Cortex M4 support includes:
- support for TI TMS470 and Keil ARM compiler;
- support for single and multi stack configurations;
- ISR interrupt supported;
- support for TI STELLARIS ICDI and Keil ULINK2 USB JTAG Debugger.
- Supported compiler:
- IAR Embedded Workbench compiler and debugger tool suite.
- TI Code Composer Studio compiler and debugger tool suite.
- KEIL uVision compiler and debugger tool suite.
- Mode of operation:
- Mono-stack: The Monostack configuration of the ERIKA Kernel models the fact that all tasks and ISRs in the system share the same stack.
- Multistack HAL: Every thread can have its private stack, or it can share it with other threads.
MCUs
- The MCUs currently supported are the following:
- NXP LPC12xx.
- TI Stellari LM4F232xxxx.
Libraries
- The software libraries currently supported are:
- Cortex Microcontroller Software Interface Standard (CMSIS) Version 2.1.
Boards
- The boards currently supported are the following:
- NXP LPCXpresso LPC1227 demo board.
- TI Stellaris LM4F232H5QD evaluation board.
- List of functions:
- Currently the NXP LPCXpresso demo board is supported through the CMSIS library.
- Currently the TI Stellaris LM4F232H5QD evaluation board through the AUTOSAR Drivers.
Examples
- The examples and tests are available in the new release (see below...).
Choosing compiler
It is possible to choose the path of the compiler in three different ways:
- environment var:
- IAR compiler: the IAR_CCDIR variable is able to override the path compiler set in RT-Druid during the build progress.
- TI TMS40 compiler: CCS_INSTALL_ROOT variable is able to override the path compiler set in RT-Druid during the build progress.
- Keil ARM compiler: ARM_ROOT variable is able to override the path compiler set in RT-Druid during the build progress.
- configuration file:
- command line versions of RT-Druid accept a configuration file, usually located at configuration/common_oil.pref.
- This file is in the java properties format (i.e. each line is composed by keyword=value). The keyword preference_cortex_m0__path_for_cc_compiler can be used to set the compiler path for Cortex MX.
- command line versions of RT-Druid accept a configuration file, usually located at configuration/common_oil.pref.
- gui:
- inside eclipse preferences, it is possible to set the path of Cortex MX complier
Download and install
- The Cortex MX plug-in for Eclipse is part of the official distribution of RT-Druid.
The procedure to install (or update) Erika and RT-Druid plugins is described at Tutorial: Update ERIKA and RT-Druid.
