<div>Thanks Joel..<br>

It is working now but while I used clock driver with timer I
didn't get any compiler error..<br>

I am glad to know that worked.<br>
<br>
I have a patch in my tree so next time someone will get a compile
error.<br>
You can only specify one of need clock, need timer, or do not need
clock.<br>
There were checks for having 0 defined but not > 1. <br>

Hi,<br>
I am just running a small Init task in which I am
creating a "timer". But the status returned by the
"rtems_timer_create" function is "RTEMS_TOO_MANY ". I
think, this status is referring to a maximum numbers
of objects already allocated. But in my task I am just
creating one timer. Do I need to preconfigure before
using the timer? For now I am using following macros:<br>
<br>
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER<br>
#define CONFIGURE_INIT_TASK_ATTRIBUTES
RTEMS_FLOATING_POINT<br>
#define CONFIGURE_APPLICATION_NEEDS_TIMER_DRIVER<br>
<br>
Can someone tell me what I might be missing? I am
currently running my task on sparc sis simulator.<br>
<br>

You can't configure the timer and clock driver at the same
time.<br>
This should have resulted in a compile time error. On most
BSPs,<br>
these use the same hardware so it is considered a general
error.<br>
Besides, the timer driver is for a "benchmark timer" used by<br>
the RTEMS Timing Test Suites -- and they assume no clock
tick.<br>
<br>
I don't know why your initialization task needs floating
point but<br>
that is your application's requirement.<br>
<br>
If you are creating a Classic API timer via the
rtems_timer_create()<br>
method, then you need to configure the system to account for<br>
how many instances of Classic API Timers you need.
Something<br>
like this:
<div class="im"><br>
<br>
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER<br>
#define CONFIGURE_INIT_TASK_ATTRIBUTES
RTEMS_FLOATING_POINT<br>
</div>
#define CONFIGURE_MAXIMUM_TIMERS 1<br>
<br>
If you need more than one timer, then up that number.<br>
<br>
If you want standard in, out and error to work (e.g.
printf()), then<br>
you should also have:<br>
<br>
#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER<br>
<br>
I just posted a re-write of the Configuring a System chapter
in the<br>
Users Guide. Everything you should need to know is in it and<br>
hopefully better presented than the current version.<br>

The current version is terse where the new version includes<br>
more information in a more structured fashion. :)<br>
