Manipulate Ram in an LPC4078

Hey Stephen,

I just saw that I am in the wrong forum. No I don't use the Arm Developement studio.

I want to alter what is written in the ram or move it from one point to another. Basically I am searching for the pointer which one I can do that. Or is that not possible?

Thanks in advance.

Pointers are just numbers.

uint32_t *src = (uint32_t) 0x20000000;
uint32_t *dst = (uint32_t) 0x20010000;
uint32_t temp = dest[100];  // save original dest word 100
memcpy(dst, src, 32768); // copy 32k bytes from start of RAM to later in RAM.
dest[100] = temp;  // restore that one word to old value

I believe that all Cortex-M processors have their internal RAM at 0x20000000.

You must of course be careful not to overwrite RAM that is already in use by other code.
