Programming EPROM

I'm using the MCB251 board with the Intel 80C251SB CPU.

I'm trying to program an EPROM using the hex file that uvision creates. My project tests fine using the Monitor Eprom with debug but I can't get it to do anything with a user eprom that I programmed.

Any help would be greatly appreciated.

1. Do I have to include the Start251.a51
to my project?

  • I finally got he config bytes in but my program still doesn't work.

    I'm trying to get the blinky program that came with the software to work from an eprom.

    I have the DIP switches set as:
    uart-int-off
    uart-ext-off
    src/d2 -off
    page -off
    monitor -off
    51/151 -off
    Map1 -off
    Map0 -off
    A17 -off

    I tried the configuration bytes you sent but it did not work.

    Any help on this will be appreciated.
