Hi Customer,

You don't need to port it by yourself, because we already have the FreeRTOS code in the KSDK for MK22 chip.

Please download the SDK code from this link:

Welcome | MCUXpresso SDK Builder

Select the chip which you want, then note the following steps:

Select the FreeRTOS, then download the code.

You can find the freeRTOS code in folder:

SDK_2.3.1_FRDM-K22F\boards\frdmk22f\rtos_examples

Wish it helps you!

Have a great day,
Kerry

Hi Kerry

Thank very much, I have found and look at the code .

I would like to ask why there is no priority grouping. There was a grouping function that was previously used in ST is this function: NVIC_PriorityGroupConfig(NVIC_PriorityGroup_4);

Hi hg,

It's the chip's character, NXP chip is a little different with the ST chip.

So, please use our official code, if you still want to use the group, you can refer to the ARM cortex M4 core reference manual to call the according code.

If you meet some problems about, please kindly let me know!

Have a great day,
Kerry
