Any FreeRTOS demo on MM9Z1J638?

[yuehedeng]

Currently, I'm trying to port FreeRTOS into my platform.

My device is MM9Z1J638(S12Z core) + CodeWarrior 10.6.

But I'm not familiar with s12z register and asm instruction writing. So is there any FreeRTOS demo based on s12z from NXP?

Hi Yuehe,

Unfortunately, I am afraid there isn’t any official MM9Z1J638 FreeRTOS port from Freescale/NXP side.

If I remember correctly, there was a plan for some OS implementation on S12ZVMC256 and S12ZVC192 (S12Z derivatives with enough memory sizes), but I am not sure whether it is FreeRTOS and status of this activity.

Anyway, there is a note at FreeRTOS Community about successful porting:

The Freescale folder at FreeRTOS Community also contains various S12/S12X ports. The S12Z port should be simpler since we do not need to care about paging mechanism…

I would like to recommend Erich’s page as the great source of useful information related to RTOS:

I hope it helps you.

Have a great day,
Radek
