Multicore MPC5748G FreeRTOS Example

Im trying to put together a FreeRTOS example using all 3 MPC5748G cores.  Im having a tough time.  I am starting with the single core FreeRTOs example and duplicating it.  Trying to mimic the multicore interrupt example

All Id like to do is have one task scheduled to run in each core blinking an LED and be able to debug each core individually.

Ive added many things to the Project Properties Preprocessor defines like this:

-std=c99 -DSTART_FROM_FLASH -DCPU_MPC5748G -DTURN_ON_CPU0 -DTURN_ON_CPU1 -DTURN_ON_CPU2 -DDEBUG_SECONDARY_CORES USING_OS_FREERTOS

I get one of those "uncensored errors"

Has anyone an example of FreeRTOS running on each core?

Hi Daniel,

Freertos is not a multi-core OS. Each core can host own freertos instance but it will require more effort to implement it due to shared resources. I'm not aware of such example.

Regards,

Lukas

Thanks Lukas. I understand it’s not a multi core OS. Was hoping to load three instances. One free RTOS for each core. Each instance also to load from an separate 256k flash partition
