Hi Simon,
Thanks for ther reply! I am still not clear about booting barrelfish on
more than one core. The document
mentioned above only talks about reseting core 0 to boot barrelfish but
doesn't mention anything about
bootscc.sh. The section for booting on subsequent cores (section 2.5) only
talks about telling the CPU driver
to boot other cores but doesn't say how to do that.

Thanks
