完整函数如下：
/*---------------------------------------------------------------------------*/
void
reset_handler(void)
{
unsigned long *pul_src, *pul_dst;
REG(SYS_CTRL_EMUOVR) = 0xFF;
/* Copy the data segment initializers from flash to SRAM. */
pul_src = &_etext;
for(pul_dst = &_data; pul_dst < &_edata;) {
*pul_dst++ = *pul_src++;
}
/* Zero-fill the bss segment. */
__asm(" ldr r0, =_bss\n"
" ldr r1, =_ebss\n"
" mov r2, #0\n"
" .thumb_func\n"
"zero_loop:\n"
" cmp r0, r1\n"
" it lt\n"
" strlt r2, [r0], #4\n"
" blt zero_loop");
/* call the application's entry point. */
main();
/* End here if main () returns */
while(1);
}
/*---------------------------------------------------------------------------*/
