This board support package has not been tested with multiprocessor

or the timing support.  The uniprocessor IDP package was tested though

with a fairly large application (although bugs may exist).  The

$RTEMS_ROOT/src/tests/Makefile should therefore have the samples and

the tests directories compiled first with the tmtests (timing) and

multiprocessor directories optional.

Let me know if you have any problems or bug fixes.  Bug fixes are greatly

appreciated.  I do not work for RTEMS or am a member of the RTEMS support

group in any way, however.  I am just one of many that appreciate

"free" software and enjoy contributing when possible :).  You can do it too!

==============================================================

Notes: Make sure that -msoft-float is defined when compiling in the

newlib-beta-rtems/newlib/msoft-float directory subtree.  You also probably

want to add the following line to line 413 of

newlib-beta-rtems/newlib/msoft-float/libc/stdio/vfprintf.c:

#define INTEGER_ONLY

That allows you to pass most of the paranoia test in the samples

directory of RTEMS although you can't see the floating point values actually

printed (software floating point tends to make that difficult anyway).

In order to pass the whole paranoia test (with one flaw), however, I had to

comment out the following line in milestone 140 (why?):

/*  printf ("Testing X^((X + 1) / (X - 1)) vs. exp(2) = %.17e as X -> 1.\n",

    Exp2); */
