It seems the second core (id=1) is not started. Did you configure
the SCC properly? <br>
What arguments did you give to sccMerge? [1]<br>
<br>
Hope this helps<br>

<br>
I assume you modified your menu.lst to start the hello
program. The menu.lst [1] for the SCC provided in the tip
version of the Barrelfish tree should not start the hello
world program automatically.<br>
<br>
Adding the following entry to the menu.lst would start the
hello program on core 0 (assuming you compiled it).<br>
<tt>module /scc/sbin/examples/xmpl-hello core=0</tt><br>
<br>
If you wanted it to start on more cores, you could add
several lines, such as:<br>
<tt>module /scc/sbin/examples/xmpl-hello core=0<br>
module /scc/sbin/examples/xmpl-hello core=1<br>
module /scc/sbin/examples/xmpl-hello core=2</tt><br>
<br>
If you omit the paramter <tt>core=</tt>, the program is
started on the core 0.<br>
<br>
Hope this helps,<br>

<div> Hi,<br>
<br>
I have manged to boot barrelfish on SCC. My question
is i have booted barrelfish on two cores of SCC and i
can see "Hello world" printed once is this correct? (i
think that core0 and core1 both will output "Hello
world" and i should see it twice on screen)<br clear="all">
<br>
Thank you.<br>
