Hi,
I am working on developing a simulator on qemu. I am faced with a bug and I
have tried solving it for three days now with no success:
Here is my problem:
I trying to simulate LPC 1768 cortex m3 based processor on qemu. But I am
unable to get beyond the libc_init_array in the newlib.
My qemu cpu jumps to program counter 0 when on jump inside init function of
__libc_init_array of newlib.
Here is the disassembly code for init:
Called from libc_init_array
0000042c <_init>:
291 42c: b5f8 push {r3, r4, r5, r6, r7, lr}
292 42e: bf00 nop
293 430: bcf8 pop {r3, r4, r5, r6, r7}
294 432: bc08 pop {r3}
295 434: 469e mov lr, r3
296 436: 4770 bx lr
I stepped through the intermediate code generation in qemu which looks fine to
me.
Also, I am not able to figure one part in qemu that is how is the cpu
environment like registers for a processor updated.
Any help would be highly appreciated.
Thanks,
