Thread: Default first RAM address?

    Default first RAM address?

    Is there a standard "starting" point for RAM addressess? Eventually in class I will have to right a program to display the contents of ram, and I was wanting to get a jump on it. ???

    Re:Default first RAM address?

    Usually depends on the processor you're using, as well as whether or not you're loading any sort of boot ROM on to the board.

    I did some assembly on a Motorola Coldfire processor a few years back and my school had put a basic boot ROM on to the board...starting address was 0x10000. However last year my school performed massive upgrades to Coldfire2 processors and put a modified Janus boot ROM on the system so user addressable memory started at 0x101000.

    You mentioned that this is for a class? Your best resource would be the prof, or the lab guy who administers the boards.

    depending on how the chip selects are mapped will affect the RAM location, if it is for PC style hardware i thinks it is at 0x00100000
