Re: [ECOS] ECOS - MIPS

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.
