Turns out that was left-over test code in rtems_init.c. I commented them out and all is now well. I believe the latest version has them removed.</div>

<div class="PlainText">Hello Pete,<br>
<br>
not entirely sure how EPICS initializes dhcpcd. But I would expect that <br>
your application creates a /dev/dhcpcd.conf somewhere. You can add the <br>
"quiet" option to that file:<br>
<br>
<a href="https://urldefense.com/v3/__https://www.freebsd.org/cgi/man.cgi?query=dhcpcd.conf&apropos=0&sektion=0&manpath=FreeBSD*13.0-RELEASE*and*Ports&arch=default&format=html__;Kysr!!P4SdNyxKAPE!XPuMFkMEYBezuIigrxyh13AlgkwIGuLGASXR88ZX4xai51nloC0B_Qsw5x2dgZw$">https://urldefense.com/v3/__https://www.freebsd.org/cgi/man.cgi?query=dhcpcd.conf&apropos=0&sektion=0&manpath=FreeBSD*13.0-RELEASE*and*Ports&arch=default&format=html__;Kysr!!P4SdNyxKAPE!XPuMFkMEYBezuIigrxyh13AlgkwIGuLGASXR88ZX4xai51nloC0B_Qsw5x2dgZw$</a>
<br>
<br>
(Note: The man page is a bit newer than our dhcpcd. But the quiet should <br>
be the same.)<br>
<br>
Alternatively there should be a call to rtems_dhcpcd_start() somewhere <br>
(maybe hidden in another call). That function allows an <br>
rtems_dhcpcd_config structure pointer as an argument. That structure has <br>
an argc and argv. Without testing: I think you could pass a "-q" or a <br>
"--quiet" in these to silence dhcpcd. Note that the first field in argv <br>
has to be the program name. So you would have to use something like<br>
<br>
const char *argv[] = {"dhcpcd", "-q", NULL};<br>
int argc = RTEMS_BSD_ARGC(argv);<br>
<br>
Best regards<br>
<br>
Christian<br>
