Intercore task activation

Kernel
1

Hello,

Free RTOS v10 onwards provide stream buffers to pass data from one core of microcontroller to other core.
(Reference: https://www.freertos.org/RTOS-stream-message-buffers.html )

Can you tell, is it possible to activate a task(Suppose, running on core 0) from core one. i.e. inter core task activation is supported?

Regards,
Priyanka

Yes. One core raises an interrupt in the other core. There are then multiple scenarios for what you might want to do in that interrupt handler - probably the simplest of which is to use something like a queue or task notification to unblock a task. See here
for an example https://www.freertos.org/STM32H7_Dual_Core_AMP_RTOS_demo.html
