Hi again,
Got this working. Repositioned, ptr1, ptr2 assignment after the assembly usage:
#include <common.h> #include <exports.h>
int main (int argc, char *argv[]) { unsigned long *ptr1, *ptr2;
/* not here */
asm volatile ("ldr r0,= 0x30800000"); asm volatile ("ldr r3,= 0x30800004"); asm volatile ("ldr r1,= 0xff000000"); asm volatile ("movs r2, r1, lsl #1"); asm volatile ("mrs r1, cpsr"); asm volatile ("str r1, [r0, #0]"); asm volatile ("str r2, [r3, #0]");
/* placed here */
ptr1 = (unsigned long *) (0x30800000); ptr2 = (unsigned long *) (0x30800004);
printf ("*ptr1 = %8lx\n", *ptr1); printf ("*ptr2 = %8lx\n", *ptr2);
return (0); }
Regards,
SK
