Dear all,
In linkcmds, I find out that there is a block of memory called NOCACHE, with
the length of 1MB. What is this memory for in RTEMS?

I tried it, and it worked.
But, there is another problem that I need to free this array (or buffer) by my
self. This bunch of buffer can not be freed by calling pthread_attr_destroy.
Maybe this is a little inconvenient.
Any suggestion on this?

You mean, I allocate an array of some size in another thread, and set the
