*Hi*
*I made a script describing a multicore system based on ARM (cortex A9) it
works fine when u tested it with "hello world!" example but when i added
the checkerCPU like so:*
np = 4
system = System(cpu = [O3_ARM_A9_3(cpu_id=i) for i in xrange(np)],
mem_mode = 'timing',
mem_ranges = [AddrRange('512MB')],
cache_line_size = 64)
system.clk_domain = SrcClockDomain()
system.clk_domain.clock = '1GHz'
system.clk_domain.voltage_domain = VoltageDomain()
#-------------------------------
# Addeing !checkers to each CPU
#-------------------------------
for i in xrange(np):
system.cpu[i].addCheckerCpu()
#-------------------------------
# Defining I & D L1-caches and connecting them to the CPU side
#-------------------------------
for i in xrange(np):
system.cpu[i].icache = L1ICache(options)
system.cpu[i].dcache = L1DCache(options)
# Connect the instruction and data caches to the CPU
system.cpu[i].icache.connectCPU(system.cpu[i].icache_port)
system.cpu[i].dcache.connectCPU(system.cpu[i].dcache_port)
*But, when i simulate the script, I get a segmentation fault :*
command line: build/ARM/gem5.opt 'ARM _A9/ARM_A9_Config.py' --l1i_size=64kB
--l1d_size=32kB --l2_size=2MB

*Anyone have a good idea about that ?*
