The eCos reference material has great information on the topic of porting
in Section III, Chapter 11.

I have also written an article for Embedded Systems Programming Magazine
which might help you out in the January 2002 issue.

The book, Embedded Software Development with eCos (ISBN: 0130354732), also
has a chapter on porting that might help you out.

Hope this helps.

Anthony

I know well pSOS.
I am learning eCos now and trying out applications in i86.
Where can I get a few sample applications ?

Jonathan,

Setting the baud rate did the trick for me.
It worked.

Thank you very much.

Did you set the baudrate in GDB with:

set remotebaud 38400

You can also do this by invoking GDB with "-b 38400".

Yes.

Is there any special setting that I am missing ?

What GDB are you using? You are using i386-elf-gdb, right?

Jorg,

That is exactly what I got, before I gave up.

Sorry, I cannot help you because I never figured out what is happening. It 
would be nice if someone that got this target working at some point, verify 
if it is broken on this release.

As far I can tell, the PC target does not work on this release.
I hope I am wrong, and it is just a configuration problem.

Rosimildo.
