   > @xiaoxiang781216 - This precludes a statically defined system. It should not brought in.
   
   Here is my thought:
   
   1. All public API task_create/kthread_create/posix_spawn doesn't accept stack pointer as argument
   2. nxtask_init still do the dynamical allocation internally(e.g. task_group...)
   
   If the statical allocation is the target, the public API should accept the stack pointer at least. Do you think it's better to add stackaddr field in posix_a like this:
   ```
   struct posix_spawnattr_s
   {
     FAR void *stackaddr;           
     size_t        stacksize;
   };
   ```
