FreeRTOS or MQX? - Problems while importing RTOS using Processor Expert

[vishalgirisagar]

Hello,

1.  I want to use RTOS for my application. I am using Kinetis series K22FN512 MCU. Which RTOS is better? 

2. Is Processor Expert free of cost. ? If yes, I got following error today -

Jun 9, 2015 4:38:49 PM Starting Processor Expert service

System directory = C:\Freescale\KDS_3.0.0\eclipse\ProcessorExpert

Internal cache directory = C:\ProgramData\Processor Expert\PECache\6e5874fa

Processor Expert license file = not used (no license file)

3. Also I am using Kinetis Design Studio IDE for compiling. I am facing some weird problems. Not able to see "Kinetis SDK", "Free RTOS" and "MQX" in component library. I am following the tutorial in below link. Please help me.

Hi,

please select your RTOS within fsl_os_abstraction component (OSA). Details below:

RTOS preference is up to you, I would select FreeRTOS.

There exists now two FreeRTOS components. One is delivered by default with PEx for KSDK 1.2.0 second is developed within MCU online page. Components from this page must be installed extra.

best regards

Hi Vojtech,

  Thanks for your reply. I understand how to select the RTOS now. Can you please tell me why would you  choose FreeRTOS? Any specific reason? I mean the pros can influence me to choose it. But I want to know reason.
