Hi,<br>
<br>
this is harder to fix than I originally though. I will take some
time to fix (especially since I am a little busy right now).<br>
<br>
Maybe you want to use an earlier version of Barrelfish in the
meanwhile, e.g. revision release2011-09-02?! Since then, nothing
significantly changed for the SCC code anyway. That one works fine
on our SCC. In case you revert, make sure to do a clean rebuild!<br>

Hi,<br>
<br>
I'm trying to boot barrelfish on SCC. I've managed to
compile the source,<br>
get barrelfish0.obj and <a href="http://barrelfish48.mt" target="_blank">barrelfish48.mt</a>.<br>
Then I use the bootscc.sh to boot it. For test, I just want
to boot core 0<br>
and core 1, but a weird problem<br>
happens: core 1 is trying to boot core 0. Here is the output
after system<br>
start.<br>

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

Hi,<br>
<br>
can you try replacing<br>

with<br>
module /scc/sbin/spawnd boot bootscc=1<br>
and try it again?<br>
<br>
