Hi All,
I am trying to run a basic program of memcpy for which I am seeing the
following error.
"build/ARM/sim/faults.cc:104: panic: panic condition !handled &&
!tc->getSystemPtr()->trapToGdb(SIGSEGV, tc->contextId()) occurred: Page
table fault when accessing virtual address 0x7ffffffe00"
Below is the program that was cross compiled (I used -static flag when
compiling):
*void memCpy(void *d, void *s, size_t n){ char *csrc = (char *)s;
char *cdest = (char *)d; for(int i=0; i<n; i++) { cdest[i] =
csrc[i]; }}*
*main()*
*{*
* char address[] = "s"; unsigned long warmup_size = 65536;
memCpy((address + warmup_size), address, warmup_size);*
*}*
Below is the command that caused the fault:
*./build/ARM/gem5.opt configs/example/se.py -cmd=memCpy*
Please let me know how I can resolve this. Does gem5 have a protected
region that should not be accessed.

Thanks and regards
Siva
