i change the code like this: -------------------------------------- #define ADDR ((volatile unsigned *)&buf)
int start_kboot()
{
asm volatile("mov pc, %0\n"
: /* output */
:"r"(ADDR) /* input */
);
return 0;
--------------------------------------
and this .s file changed :
ldr r3, .L3
#APP
mov pc, r3
----------------------------------------
i think the assembly code is right.
but the led still not blink.
