[Barrelfish-users] Barrelfish Hello world on SCC

[Nil Karavadara]

HI,

I have made changes (only menu.lst needed changes) but the out put is still
the same.

*Output log:*

# spawnd is used to control which cpus are booted
#
# "spawnd boot" will use the skb and pci to figure out and
#  boot all cores in the machine
#
# "spawnd boot bootscc=1-6" will not use the skb and
# boot the list of cores passed as argument.
# The hardware id of the cores to boot should be specified.
# This list may not include the bsp core id.

module /scc/sbin/examples/xmpl-hello core=0
module /scc/sbin/examples/xmpl-hello core=1

Is there anything ma i missing?

Thank you,
