HI,
Thank for quick reply.
I am using sccboot.sh to boot barrelfish on to cores
*bootscc.sh*
#!/bin/bash
#
# Starts Barrelfish on SCC
# Reset CRBs and everything else
sccReset -g
# Create an SCC memory image & LUT mapping
sccMerge -m 8 -n 12 -noimage -lut_default -force barrelfish02.mt
#sccMerge -m 8 -n 12 -noimage -lut_default -force barrelfish12.mt
#sccMerge -m 8 -n 12 -noimage -lut_default -force barrelfish48.mt
#sccMerge -m 8 -n 12 -noimage -lut_default -force barrelfish24.mt
# Preload memory with image
sccBoot -g obj
# Release reset of core #0
sccReset -r 0
# Watch the output of all cores as it goes...
./watchall.sh*
watchall.sh*
#!/bin/bash -i
#
# Shows output of all Barrelfish SCC cores simultaneously, as it arrives.
trap "pkill -P $$" SIGINT
for i in `seq 0 1`; do
# XXX: We use grep here to enforce line-buffered output, so concurrent
# input from UARTs isn't garbled.
# cat /dev/crbif0rb0c${i}ttyS0 | grep . --line-buffered &
cat /dev/crbif0rb0c${i}ttyS0 &> $HOME/core${i}.log
done
