This is related to my earlier post, but I ll post this as a separate
thread to state my problem clearly. I have been trying to do this in
several ways but to no avail. Here's what I tried.
1. VExpress_ELT DOES have an ethernet interface inside it. When I run fs.py ie:
gem5/build/ARM/gem5.opt gem5/configs/example/fs.py --machine-type=VExpress_ELT
I get the error :
warn: Device system.membus.badaddr_responder accessed by read to
address 0x10009018 size=4
gem5.opt: build/ARM/cpu/simple/atomic.cc:289: Fault
AtomicSimpleCPU::readMem(Addr, uint8_t*, unsigned int, unsigned int):
Assertion `!pkt.isError()' failed.
2. RealViewPBX does NOT have an ethernet interface and runs correctly
when I run fs.py ie
gem5/build/ARM/gem5.opt gem5/configs/example/fs.py --machine-type=RealView_PBX
3. Now, I add an ethernet interface to RealViewPBX by copying the
relevant portions (which refer to the variable ethernet) of
VExpress_ELT inside src/dev/arm/RealView.py. The lines are :
In attachIO():
-----------------------------------------------------------------------
self.ethernet.pio = bus.master
self.ethernet.config = bus.master
self.ethernet.dma = bus.slave
In class RealViewPBX():
-----------------------------------------------------------------------
ethernet = IGbE_e1000(pci_bus=0, pci_dev=0, pci_func=0,
InterruptLine=1, InterruptPin=1)
This doesn't work, and I get the error :
fatal: system.iobus has two ports with same range:
system.realview.ethernet-pciconf
system.iobridge-slave
@ cycle 0
I tried VExpress_EMM as well, but that has a similar "Invalid access
size" error. I am not sure how to go about fixing this.
