Hi all, Please see below a rough checklist for porting to SMP freertos. Let me know if i am missing something or something is wrong. Regards Srinivas Porting Checklist for FreeRTOS SMP Change: Definition in freertosconfig configNUM_CORES: The number of cores available to run tasks. May be set…

Of course I will contribute my port. Currently however I have an issue with the recursive spinlock implementation. After my own implementation was not working I tried the existing implementation of a Partner Supported Port for a TI Cortex A53 CPU (found here: Source/portable/ThirdParty/Partner-Suppo…

Also I encountered this: [BUG] vTaskDelay raises configASSERT when SMP is on · Issue #1068 · FreeRTOS/FreeRTOS-Kernel · GitHub

[image] jen: I narrowed to problem down to the tick Hook (vFullDemoTickHook). Whenever I comment out the function calls within, the System runs fine. Any idea why I experience such behavior? Can you try pining all the tasks to one core? You can probably use configTASK_DEFAULT_CORE_AFFINITY fo…

I’ve finished porting FreeRTOS SMP to ZynqMPSOC, and I’m currently testing it, and I haven’t found any problems at the moment

Whenever you feel you are ready, feel free to raise a PR to the following repo - GitHub - FreeRTOS/FreeRTOS-Kernel-Community-Supported-Ports .

[assert] Running main_full with all four A53 cores on will probabilistically result in the above assert Running main_full with only two cores on for 24h does not result in the above problem. But when I debugged it with the debugger, I realized that it’s not the interrupts that are missing, but t…

[rtosbug] Is it because of the interrupt latency on ARM cortex-A processors

When you ran main_full, the value of configRUN_MULTIPLE_PRIORITIES was 0 or 1?

configRUN_MULTIPLE_PRIORITIES was 0

I opened an discussion about an error that keeps happening with my spinlocks even though their implementation is verified independently. You can find it here
