Thanks for advice. I discovered that the PC has value 0x0C and SPSR of ABT mode 
is same
as CPSR so I think that is prefetch abort. But I don't understand why it 
happens? Invalid memory
access? I'm using simple linker script:

...
OUTPUT_ARCH(arm)
ENTRY(_start)
SECTIONS
{
  _start = 0x80008000;

  . = _start;

  .text : {
    *(.start);
    *(.text);
  }
...
 
Thanks in advance.
