Symmetric Multi processing in Cortex-A53 processor not working

[vivek_jorige]

Hello People,
I’m working with Xilinx Ultrascale+ Mpsoc Processor. which has cortex-A53 Processor which is quad core and Cortex-R5 processor which is Dual-core. When I’m trying to do Symmetric Multiprocessing It doesn’y show any options in config.h file like

configNUMBER_OF_CORES
configRUN_MULTIPLE_PRIORITIES
configUSE_CORE_AFFINITY
configUSE_TASK_PREEMPTION_DISABLE
configUSE_PASSIVE_IDLE_HOOK
configTIMER_SERVICE_TASK_CORE_AFFINITY
When I tried at a time only one core is working. Remaing cores are not working. And when i tried to run another application in another core then the previous core stops working.

Which FreeRTOS version and port are you using? SMP support was introduced in FreeRTOS version 11.0.0. For Cortex-A53, you should be able to use this SMP port - FreeRTOS-Kernel-Partner-Supported-Ports/TI/CORTEX_A53_64-BIT_TI_AM64_SMP at main · FreeRTOS/FreeRTOS-Kernel-Partner-Supported-Ports · GitHub.

I use Vitis class Ide . So i didn’t use any porting process as it by default supports free rtos option.

Even then you are using a FreeRTOS version and a port:

• You can check the FreeRTOS version at the top of any source file like this - FreeRTOS-Kernel/tasks.c at V11.1.0 · FreeRTOS/FreeRTOS-Kernel · GitHub.
• You can find the FreeRTOS port by checking which file in this folder you are using - FreeRTOS-Kernel/portable at V11.1.0 · FreeRTOS/FreeRTOS-Kernel · GitHub.
