# This script is inteneded to be run from inside gdb, with gdb already
# attached to the target - probably this is done in .gdbinit.
#
# You should be running gdb like this:
#
# arm-none-eabi-gdb -q -x tools/verification/tc/my_tc.py
#
#
# The useful output from this script appears on stderror, sorry about
# that. Hence you should supress stdout if you don't want loads of
# info from gdb.
#
# Something like this should work:
# > /dev/null arm-none-eabi-gdb -q -x tools/verfication/tc/my_tc.py
#
