[Barrelfish-users] barrelfish on scc, how to ping the cores

[Zhuwangbin]

Hi all,

I'm trying to run barrelfish(release2012-01-30) on scc(sccKit 1.4.2 with emac enabled, the port is emac a), but I can't ping the cores, and in the SCC performance meter widget, I can't see any alive cores.

The menu.lst.scc is as follows:

timeout 0

# 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/echoserver core=1 cardname=eMAC0_1

# RCK memory map
# Everything up til VGA is private RAM (maybe we want to throw it away)
mmap    map     0x0             0xa000          2
# Everything after VGA is private RAM (we also live in this area)
mmap    map     0xe800          0x26ff1800      1
# Shared RAM (over all MCs) in the middle of address space
#mmap   map     0x80000000      0x4000000       1
mmap    map     0x80000000      0x40000000      1
# At the very end we have some platform memory (bootup EEPROM)
mmap    map     0xfffc0000      0x40000         2


and the output is as follows(cat /dev/crbif0rb0c0ttyS0):

Whether the barrelfish is successfully booted? I can't ping the cores(core0, core1). How can I access the cores?

Many thanks for your help,

Best regards,
