FreeRTOS Integration Support for S32K344 (RTD / S32DS)

ganavi1 · ‎04-09-2026

I would like to implement FreeRTOS on this platform and need guidance on the correct approach using NXP-supported components.

Specifically, I am looking for:

Any official documentation or application notes for integrating FreeRTOS with S32K344
Example projects demonstrating FreeRTOS usage (preferably with RTD drivers)
Guidance on SysTick or timer configuration for FreeRTOS
Recommended method to integrate FreeRTOS with peripherals like FlexCAN

I have already created a basic S32DS project, but I could not find clear documentation on enabling or configuring FreeRTOS for S32K3 devices.

Could you please share:

Reference examples
Relevant documentation links
Best practices for this implementation

Hi @ganavi1,

You mention you've already created a simple project with FreeRTOS. Could you share which SW version you are using? The latest package is SW32K3 FreeRTOS 11.1.0 version 7.0.0 Code Drop. This is installed on top of the RTD package.

1. From the list of items, you can also download User Manual for S32K3 FreeRTOS. It shows how to integrate and build the product, along with the source code directory structure, how to create an application, linker file, interrupt table, etc.

2. The FreeRTOS 11.1.0 v7.0.0 includes some examples for various derivatives.

There are also some community examples you can use as reference:

3. You can configure clock and ticks from the 'freertos' component:

4. I suggest firstly importing and testing the baremetal (AUTOSAR or non-AUTOSAR) FlexCAN examples we provide. Then, you can use a basic FreeRTOS project as base and integrate the FlexCAN driver.

Best regards,
Julián
