Hi,<br>
<br>
can you try replacing <br>
<tt>module /scc/sbin/spawnd boot bootscc=0-1</tt><br>
with<br>
<tt>module /scc/sbin/spawnd boot bootscc=1</tt><br>
and try it again?<br>
<br>
The boot-up of core 0 is implicit - we do not specify it as a spwand
argument.<br>
<br>
Cheers, <br>
Stefan<br>

Hi,
<div><br>
</div>
<div>I'm trying to boot barrelfish on SCC. I've managed to compile
the source, get barrelfish0.obj and <a moz-do-not-send="true"
href="http://barrelfish48.mt">barrelfish48.mt</a>.</div>
<div>Then I use the bootscc.sh to boot it. For test, I just want
to boot core 0 and core 1, but a weird problem</div>
<div>happens: core 1 is trying to boot core 0. Here is the output
after system start.</div>

<div>As I see it, core 1 seems thought that it's the bsp core
(while it's not) so it's responsible to boot other cores. But I
fail to see why core 1 would think like that.</div>
<div><br>
</div>
<div>Any ideas on this? Thanks in advance.</div>
