| Description | FreeRTOS (www.freertos.org) implementation as component. Support for all S08 and all S12(X), ColdFire V1 (CN, JM, QE, JE, and MM families), ColdFire V2 (5225x) and all Kinetis (tested with K40, K60(F), K70/M4F, KL20Z Freedom Board). |
| Component | FreeRTOS.PEupd |
| Dependencies | Utility, FreeRTOSTrace, PercepioTrace |
Starting January 1st 2013, the latest and greatest versions of components and examples are hosted on GitHub.
A tutorial how to use the FreeRTOS Embedded Processor Expert component is used can be found here: Tutorial: FreeRTOS on DEMOJM
The component has been tested with CodeWarrior for S12(X) V5.1, which is not Eclipse based. The eclipse based CodeWarrior (MCU10.x) is using the concept of an RTOS adapter. The FreeRTOS component has now a setting to disable this. You need to set the setting 'Classic CodeWarrior' to 'yes' in order to have it working in a non-eclipse CodeWarrior environment. Otherwise you will see internal errors during code generation.
Additionally at least the PE 3.09 Service pack needs to be installed. The update is available on http://www.freescale.com/webapp/sps/site/overview.jsp?code=CW_UPDATES_MCU_63, direct link: CodeWarrior for MCU V6.3 Processor Expert V3.09 Update

| Date | Version | Description |
| 31-Jan-2013 | 1.203 | Updated for IAR. See this post. |
| 18-Dec-2012 | 1.202 | Fix: using a tick timer other than SysTick for ARM/Kinetis was not supported, now the component gives an error message for this. LDD calls to the TickTimer on Kinetis uses now properly the device handle. Implemented M4F (M4 with floating point unit) for gcc compiler. |
| 23-Nov-2012 | 1.201 | Fixed possible hard fault with gcc and higher optimization levels (above -O0) for ARM gcc and Cortex-M0+. New properties to deal with interrupt levels. See http://mcuoneclipse.com/2012/11/25/arm-cortex-m0-interrupts-and-freertos/ |
| 26-Sep-2012 | 1.200 | Updated to support different optimization levels (beyond -O0) for ARM gcc and Cortex-M0+. |
| 18-Aug-2012 | 1.199 | Update for FreeRTOS V7.2.0. This new RTOS version supports a new memory scheme 4. It is not possible any more to call vPortFree(). To help with this, the Processor Expert component defines FRTOS_MEMORY_SCHEME to identify the memory scheme used. This is used in the FSShell, so make sure you update it too. |
| 07-Aug-2012 | 1.198 | Fix for Freescale Kinetis K-Family compiler: with optimization level greater than 0 the stack was wrong for vOnCounterRestart() inside portasm.s, causing a hard fault interrtupt. |
| 18-Jul-2012 | 1.197 | Support for ARM gcc compiler (Kinetis-L and Kinetis-K family). |
| 09-Jul-2012 | 1.196 | Fix in uxGetTickCounterValue(): was using wrong type for GetCounterValue(). |
| 06-Jun-2012 | 1.195 | Supports gcc compiler and Percepio Trace for Kinetis. Make sure you update as well FreeRTOSTrace. |
| 27-May-2012 | 1.194 | Updated to FreeRTOS V7.1.1. See this post for details. |
| 14-Apr-2012 | 1.193 | Fix for Kinetis: after adding Percepio trace in 1.191/192, the Kinetis port produced code generation errors. Note that the Kinetis port has not been tested with the Percepio Trace yet. |
| 27-Mar-2012 | 1.192 | Fixed a stack problem for ColdFire V2 caused by the change from using a free running counter for the tick counter. |
| 25-Mar-2012 | 1.191 | Changed the tick counter from a periodic timer interrupt to a free running counter for the non-LDD architectures. This is required to use it with the PercepioTrace component. Note that if you have an existing FreeRTOS component in your project, you must assign a new tick counter. You have to assign a timer which modulo up/down counter, with reset on compare. |
| 11-Feb-2012 | 1.190 | Added support for Freescale S12/S12X family of processors, for Banked and Small memory model, for more details see here. Component has a setting to work as well in classic (see note for non-eclipse users). Added for Kinetis a setting to specify the optimization level of the compiler. |
| 03-Jan-2012 | 1.189 | Supporting FreeRTOS 7.1.0 and Cortex-M4F (with floating point support). Extended support for RTOS Adapter API. |
| 23-Nov-2011 | 1.188 | Fixed problem of missing include for Drivers\Sw\RTOSAdaptor\Common_RTOSAdaptor.prg. |
| 15-Nov-2011 | 1.187 | Integrated FreeRTOS 6.0.5, and using safe (no overlow) routines for vTaskGetRuntimeStats(). |
| 13-Nov-2011 | 1.186 | First version including support for Kinetis. |
| 02-Nov-2011 | 1.185 | Fixed vTaskEndScheduler() for HCS08, added xTaskResumeFromISR() wrapper. |
| 04-Sep-2011 | 1.184 | Initial release. |
