<p class="MsoNormal">I am having problems using the “select” call with an RTEMS + LibBSD network socket.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is what I am using:<o:p></o:p></p>
<p class="MsoNormal">RTEMS 5.1 RSB, RTEMS source, and RTEMS LibBSD release files.<o:p></o:p></p>
<p class="MsoNormal">ARM/Beagleboneblack + LibBSD<o:p></o:p></p>
<p class="MsoNormal">I have verified that the network is initialized (ethernet device on the beaglebone) and I can receive UDP packets from the network.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to use “select” to check the socket (using a timeout of zero), but when I call select I get a -1 return code with EBADF errno.<o:p></o:p></p>
<p class="MsoNormal">The fd in this instance is 77 and I have RTEMS setup for 200 file descriptors. Are there any other LibBSD configuration parameters I should be aware of?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I build a SPARC/LEON3 BSP with the RTEMS legacy network stack, the select call seems to work. Admittedly I am just doing this on the loopback interface on QEMU since I do not have a real or simulated ethernet device to use. But the
select call seems to work as I would expect in this instance.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there any setup I need to do, or perhaps the select call operates differently with LibBSD? Does it work on a UDP socket?<o:p></o:p></p>
<p class="MsoNormal">If I wanted to continue debugging, is the select call in the libbsd source tree?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<br>
