silRTOS Port on ARM9

I am working on wireless MAC with ARM-9 based SOC. I wanted to port
silRTOS on this ARM-9 based SOC.
As i =91m newbie to ARM architecture, can someone provide me source for
ARM port of silRTOS or help me out in porting?

Any help will be appreciated !!

Why?  What makes you think that silRTOS is suitable for your project?

What needs to be done to port this OS?

What are you paying?

We evaluated many available RTOS and found silRTOS most suitable for
our system from couple of points like
#.  silRTOS has small foot print for low overhead RAM/ROM & CPU
cycles, yet clean embedded software.
#.  silRTOS supports basic services of task/ISR/sem/Q & simple Memory
Management.
#.  silRTOS supports GNU Tool chain support with development host as
WINDOWS/LINUX.
#.  silRTOS source available freely.
#.  silRTOS provide free support available for RTOS.
#.  silRTOS provides simple priority scheduling.
#.  silRTOS provides commercial usage FREE (NO one time change, NO
productline charges, NO Royalty)
#.  silRTOS is widely used and ported to different architecture and
even used in safe-critical applications.

We couldn't find any other RTOS which is small & free. Other RTOS have
some or other constraints for usage. (Google)

silRTOS Port on ARM requires few functions to be implemented, which
are processor specific like Context switch for ARM (Processor Register
save/restore). I believe it should be fairly easy task for one who
worked on ARM.

I believe here you refer silRTOS cost, as mention above that silRTOS
is absolutly FREE for commercial usage.

Wow - there are a lot of people recently who seem to know a lot about SIL 
RTOS and want to list out all its features, 'like' they swallowed the 
marketing manual...hmmm.

>We couldn't find any other RTOS which is small & free.

No, I've never heard of any either.  Actually, hang on a minute, now I've 
thought of a several.

Yes, it looks as it is marketing manual as we evaluated around 30
different RTOS datasheets and found most of them mentioning good about
their RTOS and bad about others. All claim to be best & numero uno's :-
(  but that i don't believe to be true. We selected silRTOS looking
more for cost from our requirement.

Is FreeRTOS & SafeRTOS are free for commercial usage like silRTOS ?
Also let us know for any other free RTOS?

>Is FreeRTOS & SafeRTOS are free for commercial usage like silRTOS ?

FreeRTOS.org can be used for free in commercial applications.  Overview of 
T's and C's are here: http://www.freertos.org/a00114.html.

SafeRTOS is a fully safety qualified product and not free (although very 
reasonable).  Of course if it is purchased with the qualification evidence 
and/or consultancy then all things are negotionable :o)

How are you calculating cost to your project?  Cost to purchase, cost to get 
the system up and running, or cost over the lifetime of your product?  Here 
I'm talking about 'cost of ownership', not purchase or license costs. 
FreeRTOS is free to download and use, it also benefits from the verification 
and validation provided by the SafeRTOS developments (although the two 
products are different), but there is commercial support and development 
available should you need it (saving you time and therefore money).

You say it is free and then put T's and C's to follow else PAY :-(.
Also one surely needs
support / assistance for initial development on RTOS and here again
PAY. Also why should
one reveal that his product uses xyz RTOS in competitive world?  For
curiosity, does anyone
use FreeRTOS for Wireless LAN client bases SoC?

Understand your point, but if you can get 'cost of ownership'
absolutely free
with support & assistance, why should one PAY.  It is more like
Windows versus
Linux, but still there are people who prefer to use LINUX including
me.


By the way got the ARM port for silRTOS and its running for me.
Thanks for help & assistance from google group. Encourage people to
use
<Newsgroups: comp.arch.embedded> google group :) for any queries.

>You say it is free

It is.

>and then put T's and C's to follow else PAY :-(.

What do you expect?  The T's and C's are VERY liberal, designed to make it 
as easy for you as possible, but exist to protect me.

>Also one surely needs

>PAY.

Are you expecting free support for a free product, for life?  As it happens 
there is a very active support forum for FreeRTOS.org that is FREE FREE 
FREE!!!


Here are some questions for you -

1) What are you making?
2a) Can I have it for free?
2b) If not why should I pay for it?
3a) Will you give up your time to teach me how to use it for free?
3b) If not, why not?

...From my side the answers are:
1) A high quality mini real time kernel.
2a) Yes.
2b) Not applicable.
3a) Sometimes, you can use the free support forum and get lots of good 
advice (often from me).
3b) Not applicable.


>Also why should
>one reveal that his product uses xyz RTOS in competitive world?

That is the nature of open source software.  Many open source products 
require that you also give >your< source code away.

The only thing I could find about "silRTOS" was a web page that 
indicated it could be downloaded for free, yet it was just a hyperlink 
to a mailto: address.
