Re: [eCos] How to make a GDB awared Redboot floppy image on 386 platform
David,
There is no realtek like drvier there. and more, you did not talk about
what kinda ethernet controller
you used. I know there are about three kinda MAC what realtek has. If you do
not have eth driver, you can
do your work still. I think serial port is basic way to do anything with
redboot. via serial port, you can use gdb
to debug your program in .elf format. Under windows environment, the file
extension is .exe, but it is still elf formated.
you can dump the first several bytes and you will read what I mean. and
.bin and img formats, i think you do not
think of them.

Subject: [ECOS] [eCos] How to make a GDB awared Redboot floppy image on 386
platform
Dear eCos experts,
I am a newbie in eCos and I'm wondering if you could answer some of my silly
questions since you are also using GDB+Redboot on i386 platform. Let me
first explain what I want to do. It's very simple. I want to boot the target
PC with a floppy and use GDB to load application image via serial line
(what format of the image file should be? .img, .rom, .elf???) into the
target PC from the host PC (ethernet would be better, but unfortunately I
don't have Intel's NIC, only Realtek's ).
I don't know whether I need to rebuild a redboot image or Redhat's prebuilt
Redboot binary (redboot.bin and redboot.elf) is sufficient to cowork with
GDB debugging. If I need to rebuild Redboot, could you tell me what
options should I select in the configuration tool? I've tried to do this
many times but every redboot.bin I made doesn't boot. What I know at this
time is how to create a boot floppy with Redhat's prebuilt redboot.bin with
UNIX dd command.
I'd appreciate if you could help me or give me any hints on the web for
reference. Thank you very much.
Sincerely yours,
