LPC1768 copy function code for flash to RAM

I use the LPC1768 board and I want to copy a function from flash to RAM in runtime. I use the following code

void f()
{ int x=0; printf("%d\n",x);
} void g()
{ int x=5; printf("Hello: g"); printf("%d\n",x);
} int main(void)
{ char c; static void (*fnRAM_code)(void) = &f; int offset= (int)((long)g-(long)f); int i=0; int z=0; int *x; extern void uart0_init(void); unsigned char *pCodeStart = (unsigned char *)f;

uart0_init();

//(*fnRAM_code)();

//thump2 addresss /* Thumb 2 address */ pCodeStart = (unsigned char *)(((unsigned int)pCodeStart) & ~0x1); while (i < PROG_SIZE) { ProgRamSpace[i] = pCodeStart[i]; i++;

} (*fnRAM_code)(); fnRAM_code = (void(*)(void))(ProgRamSpace); (*fnRAM_code)();
}

But when I access the new address of the function I get the following error access violation at 0x100000018: no execute /read permision. Can anyone provide a solution for this issue
Best regards,
George
