[ECOS] Question for eCos

[ECOS] Question for eCos

[박세준]

Hello. 
My name is se-joon, Park. 
I am working at Trigem Company, in Seoul, KOREA.
We have a project about developing embedded system using embedded linux.
Thesedays, we studying the EDK tool and eCos.
And we have some question. If you know, answer us please...

Now we installed the eCos v1_3_1 and cygnus program with windows 2000
professional version.
We will trying setting the target system(x86) and boot with ram or flash
memory and connected by LAN with host.
(no hard-disk, 16M under size ram)

1. In eCos, how can we create the kernel image?
2. In eCos, how can we create boot loader image?
3. With eCos, how can we setting the connection between host and target
system?
4. In eCos, is that possible adding new package which is not exist in
package administrator tool.
    We want modify and optimize the eCos kernel and add this by new
package. Is this possible?
5. Where can we get or download the eCos v1_4_x? We cannot find in redhat
homepage.
6. How can we test the example application between host and target system?

We downloaded the manual from redhat homepage by .pdf file, but cannot
understand well...
If you know the partial of above question, please send us the detail
answer...
Best regards.

Sincerly, se-joon, Park.

There is a good guide for configuring your first x86 ecos applications
on the eCos web site.

 < http://sources.redhat.com/ecos/docs-latest/tutorials/i386pc/ecos-tutorial.2.html >

Once you've mastered the floppy-based stub loader, you can use a patch
I've written to boot from either flash or from a hard-drive.

Firstly, don't send mail to ecos-announce - you didn't have an
announcement! Secondly, don't send mail to the cygwin list - your problems
are specific to eCos.

I hope you realise that eCos is _not_ Linux.

The x86 target only supports floppy booting at this time. You start by
writing a "gdb stub image" to that floppy, which in turn allows you do
download applications over serial, to start off with. To build the image
and write the floppy, refer to the i386 getting started guide at
http://sources.redhat.com/ecos/docs-latest/

Serial is all that's possible in eCos 1.3.1. There are some patches
available to support ethernet debugging with RedBoot.

Yes. I won't go into details now as I suspect it will be some time before
you get to the stage of creating your own packages.

It has not been publically released. The next public release will be 1.5.
You can get sources roughly equivalent to the 1.4 series releases from
anonymous CVS - http://sources.redhat.com/ecos/anoncvs.html
