Unable to find matching request

[mazhulin]

when I followed SST_Tutorial_overview and learned the example(Miranda CPU<->L1 Cache<->Memory), I wrote a configuration file according to the tutor. However, when i used command (sst -v configFile.py) to run the file, there are some errors as following:

FATAL: (core interface) Unable to find matching request. Event: ID: (48,0), Cmd: FetchInv Src: L1 Dst: core Rqstr: L1 Flags:[] MemFlags: 0x0 Addr:0x0 Baseaddr: 0x0 (Global) VA: 0X0 IP:0X0 size:64 prefetch: false.

what should i do to resolve this problems?

@mazhulin will you post the python script that you're using (configFile.py)?

My configFile.py is as following:

Automatically generated SST Python input

import sst

Define SST core options

sst.setProgramOption("timebase", "1 ps")
sst.setProgramOption("stopAtCycle", "100ms")

core=sst.Component("core","miranda.BaseCPU")
cache=sst.Component("L1","memHierarchy.Cache")
memory=sst.Component("memory","memHierarchy.MemController")

core.addParams({
"clock":"2.4GHz",
"generator":"miranda.STREAMBenchGenerator",
"generator.n":"1000",
})
cache.addParams({
"cache_frequency":"2.4GHz",
"cache_size":"2KB",
"associativity":4,
"access_latency_cycles":2,
"mshr_latency_cycles":2,
})
memory.addParams({
"backend.mem_size":"20MB",
"clock":"2.4GHz",
})

core_cache=sst.Link("core_to_cache")
cache_mem=sst.Link("cache_to_memory")

core_cache.connect(
(core,"cache_link","100ps"),
(cache,"high_network_0","100ps")
)

cache_mem.connect(
(cache,"low_network_0","100ps"),
(memory,"direct_link","100ps")
)

When i run this config file with "sst configFile.py", it will prompt me with the following error message:
