[ECOS] i386 redboot and loading application

[ECOS] i386 redboot and loading application

[Agus Ariffianto]

Dear ALL,
I built a redboot disk and it works fine (I guess). After booting using
the disk, the RedBoot> prompt (is it a shell or what?) turn up.

The monitor displays:
RedBoot(tm) bootstrap and debug environment [FLOPPY]
Non-certified release, version UNKNOWN - built 10:40:03, Jul 11 2006

Platform: PC (I386)
Copyright (C) 2000, 2001, 2002, 2003, 2004 Red Hat, Inc

RAM: 0x00000000-0x000a0000, [0x0007d070-0x000a0000] available
RedBoot>
 
I want to load a program (let say a simple program: Hello world) to be
loaded into memory. What I did is (I don't know exactly wether what I'm
doing is correct or not) I remove the redboot disk and replace it with
second disk which contains the application program. The program is in
binary format. What I did to create this program is:

[agus]$ i386-elf-objcopy -O binary hello.ecos hello.ecos.bin
then copying the .bin file into the second disk.

(hello.ecos is an ecos based program)

To load the .bin program into memory, I enter command:
RedBoot> load.ecos.bin -v -b 0x00000000
No default protocol!

My questions are:
1. Why this "No default protocol! " message turn up?
2. Am I on the right track?
3. What is the command to load the application program

Your response is highly appreciated. Thank you.

Rgds,
Agus
