Hi all,

I want to make eCos application (ex: hello world) run on x86 target pc without stubs.
I wish the eCos boot from floppy or HDD without any assistance from host.
How should I do?
Thanks in advance.

Thanks for your help : )
I followed your advice to build a kernel with stub template.
But when I compile the sample hello.c, I get an error that it can't find stdio.h.
What components should I add to the stub template package?
I am new to eCos, so my question may be kind of stupid ones :-P
Thanks again.

Select stub as the template.
Set pc platform startup type as "floppy",
and disable all the configurations with gdb stubs and debugging support concerned.
When the build completes,a new eCos kernel is produced.
Compile user applications on this kernel,and get a execute file.
Using objcopy utility,convert it to a binary image file as follows.
i386-elf-objcopy -O binary hello hello.bin
Copy this image to floppy disk and then this disk can be used to boot the system.
Good luck.

Due to my poor English, Here list the translation of my mother tongue,also yours :)

No, you use the stubs template to build a boot loader image which you find
in install/bin.

If you want to build an application you must create a completely new
configuration in a separate directory - don't use the stubs template.
