[ECOS] eCos on iPaq

[Cristiano Ligieri Pereira <cpereira at ics dot uci dot edu>]

Hi everybody,

I've been struggling to make the simple Hello World application to execute
on the iPaq but unfortunatelly without success.

First I'm compiling the application and generation the binary file "hello"

Then I'm executing RedBoot using the Win/CE OSLoader. The input/output of
RedBoot goes to my /dev/cua0 since the serial cradle is connect to COM1.
>From this point on I've tried some variations from which I'm describing
the one I think is more correct.

>From Redboot prompt I simply type '$' and as far as I understood the GDB
stubs take over and I'm supposed to connect to the ipaq using gdb. ThenFor
this I'm issuing 'arm-elf-gbd -nw hello'. After typing 'set remotebaud
38400' and 'target remote /dev/cua0' I'm issuing the command 'load'. Here
are the messages I'm getting:

[my machine prompt]# arm-elf-gdb -nw hello

(gdb) load

As you can see the file in not being downloaded. I honestly have no idea
why? Can someone please explain me how to execute an application other
than the 'demos' provided in the webpage.

thanks a lot in advance,
Cristiano.
