Is it possible to alloc dynamic stack memory for zephyr threads?

[bon.chen]

Hi,

     I want to alloc dynamic stack memory for zephyr threads, such as k_aligned_alloc(stack_size, ARCH_STACK_PTR_ALIGN) instead of K_THREAD_STACK_DEFINE. I'm sure k_aligned_alloc has returned the memory address. But it doesn't seem to work. Is there any way to dynamically allocate stack memory for threads?

I can see that there's been some discussion about this here you may find useful: https://github.com/zephyrproject-rtos/zephyr/issues/26999. 

If you go to the bottom of the issue you'll find some commits:

kernel: add a stack allocation api

tests/kernel/thread_stack: add tests for dynamic stack allocation

Best regards,

Simon
