Thank's.
It's really the answer of my problem.
Now, my first "Hello,eCos World!" under linux was born.
But  I still have some question.
What's the different between "pc" and "linux"  target?

The linux target creates a linux executable for running under the Linux
operating system. The pc target creates executables suitable for booting
from a floppy or straight from flash on a PC.

[ECOS] Have anyone made a full evaluation test for eCos?

[survey liu]

Hi,all

My question as title. If not, would any one do it? I think Redhat should do this job for RTOS employees.

BTW: Is eCos a soft real time OS?

Best regards,

Try using "continue" instead.

If your target is i386 PC, then you need to put RedBoot on a floppy, and
download your program from a separate PC via serial or ethernet.

Alternative, if you are wanting the Linux synthetic target (which allows
you to run native linux programs), then did you choose the linux target,
rather than the pc target? i.e. "ecosconfig new linux" rather than
"ecosconfig new pc" ?

After runing the following command ,"run",under the gdb command line,
I can't see "Hello,eCos world!".
Why Segmentation fault? 
How to solve it?
Does it matter to Makefile of hello.c??
(Getting Started with eCos ,P70)
(My target is i386 pc , platform is Linux)

The last line is in the gdb mode,but I don't know what is the next step that I should do.
Can anyone tell me?
Thanks.
