I have tried to do the port myself, but there is no way to test it unless I move to a newer toolchain which supports armv7 instruction set, which brings me back to my original question...Thanks for your prompt reply though and the heads up regarding EABI

The patches are for eCos itself -- also, there's no specific Cortex support.
I wrote the EABI patches and contributed them to eCosCentric.  You could
contact eCosCentric regarding eCosPro support.

I was not aware of that, my target has a cortex core , where can I get the
patches for EABI ?...I am assuming here that the patches is for the target
and not ecos

You are aware that without patches, EABI will not work, right?

Hello;
I am using a prebuilt gnu toolchain for arm , based on gcc4.2.3, I downloaded
it from codesourcery.com ( for general arm-eabi target, and the tools are
running on a windows host). This toolchain is not dependent on cygwin, I set
the path in the configtool as C:\armtools\bin. Codesourcery  suggested using
cygpath for conversion, even though I set the correct variables, the .deps
file that gets generated during build calls the std library routines as
'C:\armtools\bin../lib/gcc/4.2.3/include/stddef.h' instead of 
'/ecos-c/armtools/bin../lib/gcc/4.2.3/include/stddef.h', as a result I get an
error saying 'Multiple target pattern error' which indicates to the former
line. Please let me know of any way to convert the windows path to the posix
path, is there any setting that I am missing?
Thanks
Sangeeta
