thank you for your answer. In the RTEMS Manual you can read<br>
that the initialization task should run at Maximum Priority (Classic API).<br>
(which sounds reasonable)<br>
<br>
If then the POSIX_Init should also be startet at that level -> POSIX prio 254?<br>
<br>
Instead of the low prio “2” ?<br>

I am not sure if this is a bug or feature, but changing this would alter the behaviour of all existing applications using POSIX initialization threads.<br></blockquote><div><br></div><div>I don't remember the rationale for this selection either.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

You can change the priority in your initialization thread or we may add a new configuration option, e.g.<br>
<br>
CONFIGURE_POSIX_INIT_THREAD_PR<wbr>IORITY<span class=""><br>
