Hi, all
I need simulate big-endian ARM binary with gem5. So I used crosstool-ng to
build a arm big endian toolchain (armeb-unknown-linux-gnueabi). Then I compiled
a helloword with this toolchain. Compilation command is:
armeb-unknown-linux-gnueabi-gcc -mcpu=cortex-a8 -mfpu=vfpv3 -mfloat-abi=soft
--sysroot=/home/wm/x-tools/armeb-unknown-linux-gnueabi/armeb-unknown-linux-gnueabi/sysroot
-static hellobe.c -o hellobe
I run this big endian helloworld by SE mode, but I got:
command line: ./gem5.opt /home/wm/gem5_new/configs/example/se.py -c hellobe
Global frequency set at 1000000000000 ticks per second
0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000
**** REAL SIMULATION ****
info: Entering event queue @ 0. Starting simulation...
panic: Page table fault when accessing virtual address 0xffffffec
@ cycle 643068
[invoke:build/ARM/sim/faults.cc, line 70]
Memory Usage: 643068 KBytes
Program aborted at cycle 7500
Aborted
I built several other big endian binaries, but all of them aborted running in
the middle. Does gem5 support big-endian ARM? How can I configure it?
Thanks for your help.
Best,
Meng Wang
