If your target is i386 PC, then you need to put RedBoot on a floppy, and
download your program from a separate PC via serial or ethernet.

Alternative, if you are wanting the Linux synthetic target (which allows
you to run native linux programs), then did you choose the linux target,
rather than the pc target? i.e. "ecosconfig new linux" rather than
"ecosconfig new pc" ?
