[ECOS] Getting started with eCOS...

[ECOS] Getting started with eCOS...

[Sarvex Jatasra]

Hi group.
I am a new member if this group, and trying to learn eCOS. 

I started with downloading the eCOS source for CygWin on windows along
with the ecos-elf-i386 tools. I ran the "configtool.exe" and was able to
build the eCOS library. But I am not able to figure out how to generate
the final executable and run it on my Pentium 4 processor. 

This is a completely naïve question, but I am stuck with it. Please
provide me further directions on how to proceed with this. Any help is
highly appreciated.

What final executable?  eCos comes in two parts - the kernel (library)
and your application.  You need to build an application using the 
library you've configured and built.

Have you read the "Getting Started" section of the online documentation?
It goes through this using the sample applications (in the .../examples
directory of the eCos sources).

You could also look at:
  http://www.mlbassoc.com/examples/build_hello.html
but it uses the command line configuration tool (I seldom use the GUI).
The principles are the same though.

Don't forget that to run a program on your x86 processor, you'll 
need some way of loading it - from FLOPPY or via RedBoot or GRUB.
You'll also need to set the startup type appropriately.

I didn't realize the CLI tool as well was broken. OK i found the post from Bart:

http://www.cygwin.com/ml/ecos-patches/2006-07/msg00011.html

I think for eCos 3.0 we need to decouple the host tools from eCos itself. That would make it easier to provide new versions every time cygwin breaks something. 

I guess it is also not helped by the fact that most, if not all, of the maintainers don't use M$. I personally have no interest in supporting the M$ tools.

The CLI tool is broken as well (as mentioned in the original post).

What is being suggested is simply to change the web page install
instructions, which don’t work.

The work on eCos has not stopped. It just appears the maintainer of the GUI configuration tool is no longer active. 

All the power users of eCos don't use the GUI anyway. They prefer the CLI tools. So i would recommend using that.

[ECOS] Getting started with ecos

[Scott Moore]

Hi, I just went through the install process. Can I make
A small suggestion?

The install instructions at:

http://ecos.sourceware.org/getstart.html

Don't actually work. Getting the current cygwin install, then
Installing the ecos source, etc, in exactly the order specified,
Will result in a config tool (graphical and command line) that
Has a bug that has (apparently) existed since 2003. Its true
that after looking around the ecoscentric links provided, I was
able to correct this, but after some waste of time.

I realize that work on ECOS has stopped, and perhaps creating a
Version that works with the current cygwin distribution might not
Be in the cards. However, would it not make sense to make it clear
On the instruction page above that you have to go get a fixed
Version of config to make it work?

Thanks,

Scott Moore
