Thread: Program to write to memory map addresses

To answer your question:

Code:

short *memory = (short *)ADDRESSOFMEMORY;

*memory = 0x1111;

That should work, I think. You'll almost certainly get a segmentation fault if you try it with most modern compilers, however.

Thanks for the info. I am in a situation where I have to run a program like this.

Also what if I have to write at 4 consequetive memory locations (say e000h,e0002h, e0004h, e0008h) with the data 0x1111.

For example I have this pseudo code:

Code:

for(memoffset=0x0;memoffset<0x8;memoffset+=2)  
    {
	memory[memoffset]=data;   
    }

how can I build up a simple program using all the above.
