SMP support for Cortex-A

Mbed OS
1

Hello,

I am looking for an information about mbed RTOS on SMP support and I can’t find any confirmation on what I am looking for.
I am working on some system level tests and I’am currently working with Zephyr. But it turned out it doesn’t support Symmetric multiprocessing for Cortex-A family.
Is it working in mbed RTOS? Would we be able to assign threads to specific cores using Cortex-A53? If so, does it also support MMU?

BR,
Michal

Hi Michal,

I have a similar query. You have mentioned that there is no confirmation about SMP support for Cortex-A family. I am not able to find confirmation about Cortex-M family also. Do you know whether there is an SMP support for Cortex-M?

Hello,

Sadly, I suppose there is no support. You can take a look at Zephyr. It has support for some Cortex cores. And there was ongoing development to extend list of supported items last time I checked. It might be also an option to port this support from similar core since it’s open source.
