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_<u></u>CLOCK_DRIVER<br>
#define CONFIGURE_INIT_TASK_ATTRIBUTES RTEMS_FLOATING_POINT<br>
#define CONFIGURE_APPLICATION_NEEDS_<u></u>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_<u></u>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_<u></u>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>

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