Re: [ECOS] Question for eCos

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
