hi!
I examined the MIPS platform ports for Ecos. I have some problems and i am a
little bit confused.
As far as i see, we cannot configure or compile ecos without selecting a
target platform. One of the Mips targets i examined was Atlas board. when i
configure ecos with configtool, it generates a buildtree with the atlas board
spesific headers.
Is there a possible way to configure ecos without using a target platform ? or
jusy empty macros or platform specific functions? I want to have a clean and
a MIPS ported code and then fill these functions according to my board. Is
there a way to do this ? I dont want to inspect atlas board specific codes
or compile atlas platform files.
please help me... i really need help!

The normal way of doing a port is to take an existing port which is
the most similar and modify it to work for your target. So if you
board is like the atlas, then use the atlas for a starting point. If
its more like a tx49 then use the tx49 as a starting point.
In the repository you need to copy the HAL files from you choosen
starting target to a directory for your target. You then need to start
making the modifications, and add the necassary entries in the
packages/ecos.db file.
There is a documentation about doing a port. See
http://ecos.sourceware.org/docs-latest/ref/hal-porting-guide.html

i dont understand why ecos restricts its users with a configtool and
templates. i want a clean makefile and module structure. not structuring with
a config tool or hardware environment. it is really diffucult to add or
remove a new file. also many files are coupled each other.
i have a board that implements mips core and different to atlas board. there
must be a clean version of ecos that includes pure mips dependencies. atlas
dependencies makes people to change their OS choice...
does anyone think that it is really configurable ? i dont think so...
OS must fit the environment, environment must not.

eCos is, compared to other embedded OS, a really highly configurable
OS, the configtool and templates are provided to support the user when
selecting an appropriate set of options that fulfill his needs. I
don't believe you want to manage the selction of the numerous features
on your own. In my opinion eCos is not really useable without the
configtool

well, eCos does (and you can find them in packages/hal/mips/arch I
think), the other directories you can see are containing
board-specific stuff). Well, and if eCos is not available for the
special board you use, you have to adopt an existing board package,
and that's the case with every embedded OS, because different boards
have different features and thus they need a (at least partly)
specific HAL.
Ciao, Fabian

Have you actually used it the way it was meant to be
used? You have to learn the _ecos_ way of doing
things, there is no shortcuts (unless you pay someone
[not me] to do the work) !.

What is so unclean about eCos? eCos is more than a
collection of .cxx files held together by makefiles.
It is a collection of reconfigurable reusable
components and this is where the cdl (component
definition language) comes in. Take a look at his link
http://www.embedded.com/story/OEG20011220S0059
its few years old but it is also nice and _short_.

You add and remove files by adding the filename to
the a cdl file. That is not harder than editing a
makefile.

There is no such thing as "pure" mips. Why don't you
just give us more details about your board. It is
much more productive than making negative inaccurate
comments about eCos. This is how it normally works
around here. You ask a question, give the relevant
details and hope that someone can help.

Hello! Its called configurable for a good reason!

People may have positive and negative comments about a SW product. Does this
group for only positive ones ? Or only positive questions ?
I have been writing SW for about 10 years. I have just examined eCOS and found
that it is configurable on some way and unconfigurable ( hard to reconfigure
) on some way. May be it is much more configurable than the existing ones but
not a super really configurable OS.
I am the user. This is a user point of view . Having a seperate HAL layer or a
structured file tree doesnt make an operating system really configurable.
Configurability means to change the operating system according to your needs
in a quick way : not being able to change it in a month...
configurable modern SW is done with SW patterns. Architectural and Design
patterns makes SW configurable, easy to change, etc... Embedded SW needs good
architectural design with really reusable architectural and design patterns.
What makes JAVA popular is these points. It is a programming framework that
fullfills these points.
eCOS is not a really framework. When you read the documentation, it seems to
be an OS framework but indeed it doesn't.
What i try to mean is we must make it better in order to make it usable in the
future.

Could you give some examples of what you would change?
