This board support package has not been tested with multiprocessor
|
6 |
|
|
or the timing support. The uniprocessor IDP package was tested though
|
7 |
|
|
with a fairly large application (although bugs may exist). The
|
8 |
|
|
$RTEMS_ROOT/src/tests/Makefile should therefore have the samples and
|
9 |
|
|
the tests directories compiled first with the tmtests (timing) and
|
10 |
|
|
multiprocessor directories optional.
|

|
Let me know if you have any problems or bug fixes. Bug fixes are greatly
|
13 |
|
|
appreciated. I do not work for RTEMS or am a member of the RTEMS support
|
14 |
|
|
group in any way, however. I am just one of many that appreciate
|
15 |
|
|
"free" software and enjoy contributing when possible :). You can do it too!

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

|
|
Notes: Make sure that -msoft-float is defined when compiling in the
|
22 |
|
|
newlib-beta-rtems/newlib/msoft-float directory subtree. You also probably
|
23 |
|
|
want to add the following line to line 413 of
|
24 |
|
|
newlib-beta-rtems/newlib/msoft-float/libc/stdio/vfprintf.c:
|
25 |
|
|
|
26 |
|
|
#define INTEGER_ONLY
|
27 |
|
|
|
28 |
|
|
That allows you to pass most of the paranoia test in the samples
|
29 |
|
|
directory of RTEMS although you can't see the floating point values actually
|
30 |
|
|
printed (software floating point tends to make that difficult anyway).
|
31 |
|
|
In order to pass the whole paranoia test (with one flaw), however, I had to
|
32 |
|
|
comment out the following line in milestone 140 (why?):
|
33 |
|
|
|
34 |
|
|
/* printf ("Testing X^((X + 1) / (X - 1)) vs. exp(2) = %.17e as X -> 1.\n",
|
35 |
|
|
Exp2); */
