Hi Sol,

   Thanks for your Input!!!

   In MCUXpresso SDK i could find support of Amazon FreeRTOS not FreeRTOS. Does this mean MCUXpresso only supports Amazon FreeRTOS?.Is Amazon RTOS free?. Also how is the support for it?

Thanks and best regards,

Prasanna

Hi, 

Yes, you are right,  these devices support Amazon FreeRTOS, it is free please check the following link for more information:

Hi Sol,

   Thanks for your support. I have few more queries as follows:

1) Why NXP doesn't provide direct support to FreeRTOS and only Amazon FreeRTOS?

2) My application needs only premptive scheduler. Is there any premetive scheduler supported by NXP for MKE14F512VLL16R and LPC54605J256BD100?

3) Amazon FreeRTOS has additional connectivity and security features for IOT based devices that might increase the footprint of this RTOS compared to FreeRTOS kernel. Is there any way to minimize or exclude these libraries in order to optimize the footprint or it is inherent in Amazon FreeRTOS?

4) FreeRTOS doesn't show compatibility for MKE14F512VLL16R and LPC54605J256BD100 microcontrollers. Are they really supported by FreeRTOS. If yes please provide any working example for reference.vipinkumarmishra gauravmore

Hi, 

1) Why NXP doesn't provide direct support to FreeRTOS and only Amazon FreeRTOS?

Amazon Web Services provide more than 100 cloud hosted services that are used by millions of customers, and in all industry sectors. A growing number of AWS services are designed for Internet of Things (IoT) applications, that is, the connection and management of internet connected devices.

Device manufacturers connect their MCU based devices to the cloud to innovate both their products and their business models. However, it takes time to build the security and connectivity components necessary for this connectivity into the device's software before that innovation can start. A significant proportion of connected MCU devices already run the FreeRTOS kernel, so Amazon chose to provide the FreeRTOS project with the resources necessary to extend their offering into fully integrated security and connectivity libraries, and ensure those libraries can be developed and supported long into the future. That enables FreeRTOS developers to spend less time on library integration, and more time on innovation.

To ensure longevity, Amazon also ensures the wider FreeRTOS ecosystem is strong, so all FreeRTOS kernel users benefit, not just those who connect their devices to the internet.

2) My application needs only premptive scheduler. Is there any premetive scheduler supported by NXP for MKE14F512VLL16R and LPC54605J256BD100?

We only support Amazon FreeRTOS for these devices.

3) Amazon FreeRTOS has additional connectivity and security features for IOT based devices that might increase the footprint of this RTOS compared to FreeRTOS kernel. Is there any way to minimize or exclude these libraries in order to optimize the footprint or it is inherent in Amazon FreeRTOS?

We only support Amazon FreeRTOS for these devices.

4) FreeRTOS doesn't show compatibility for MKE14F512VLL16R and LPC54605J256BD100 microcontrollers

Are they really supported by FreeRTOS. If yes please provide any working example for reference

For MKE14F512VLL16R and LPC54605J256BD100 only Amazon FreeRTOS.

For the devices mentioned in the link, you need to download LPCOpen,

https://www.nxp.com/support/developer-resources/software-development-tools/lpc-developer-resources-/...

LPCOpen libraries are RTOS agnostic and can be used with a simple control loop. Examples are also included in each software download package for use with FreeRTOS.

Have a nice day!

Sol

Hi, 

1) Market Launch date

MKE14F512VLL16R: Sep 2016

LPC54605J256BD100: Dec 2016

2) Errata

MKE14F512VLL16R: https://www.nxp.com/docs/en/errata/Kinetis_E_0N79P.pdf

LPC54605J256BD100: https://www.nxp.com/docs/en/errata/ES_LPC546XX.pdf

3) Market segments in which this controller is being used

Kinetis KE1xF MCUs are the high end series MCUs in Kinetis E family, providing robust 5V solution with the high performance Arm® Cortex®-M4 core running at up to 168 MHz. The Kinetis KE1xF MCU family also integrates CAN 2.0B compliant FlexCAN provides high reliable serial communication interface for industry applications, and rich suite of communication interfaces including LPUARTs, LPI2Cs, LPSPIs, and FlexIO.

The LPC546xx MCU family combines the power efficiency of the 220 MHz Arm® Cortex®-M4 core with multiple high-speed connectivity options, advanced timers, and analog features. DSP capabilities enable LPC546xx MCU devices to support complex algorithms in data-intensive application. Providing flexibility with up to 512 KB Flash and external memory interfaces, this family provides the ability to adapt as requirements change. Flash options support large, flexible internal and external memory configurations. Compatibility within the LPC54000 series enables the LPC546xx MCU family to provide a seamless migration path for increasing processing power and adding the flexibility of additionally advanced peripherals.

4) RTOS supported in each of these controller. Also RAM and ROM footprint of each RTOS

FreeRTOS for both devices, unfortunately I don’t have the RAM and ROM footprint information.

Have a nice day!

Sol
