Dear,

I am new for ecos project, and I want to port it on Samsung KS32C41000
ARM7TDMI CPU.
Do you have some suggestion?  Which process supported by ecos is similar
with this process ?

Regards,
Steve

I can't find any information about your processor on the Samsung website
(http://www.samsung.com/Products/Semiconductor/). However, it sounds like it
might be similar to the S3C4510/S3C4530 used in ARM's E7T or Samsung's
SNDS100, so the 'e7t' or 'snds' targets would probably be your best starting
point for a port.

oops sorry,
i have miss read the cpu name ...
so  S3C4510 and  KS32C50100 are the same (e7t)
and KS32C41000 should not be the same...
apologies,

hi,

I confirm that they are they are really the same cpu  just the name who is
different (probably comercial purpose ...)

I had to work for university ( ufrima-imag UJF Grenoble) on evt7 board
and some have a S3C4510 some others have KS32C50100 (olders ones) whith
wery little difents PCB  versions but exectely the same behaviour and
compiler (that was ARM tools ) and the docs from samsung are the sames.

best regards, 
Aurelien Francillon

I have found data sheet on S3C44B0X which is a similar part to the one you
mention and, yes, you're right, it's quite different.

In this case, you would still be wise to start from an ARM7TDMI core based
port, so 'e7t' or 'snds' would still be appropriate. However, you will need
to consider all aspects of the port - the cache control, UART, system
configuration, memory map, clock configuration etc. when doing the port. I
would suggest buying Anthony Massa's book 'Embedded Software Development
with eCos' (ISBN 0-13-035473-2) - this has a whole chapter on porting.
