New! How to port eCos to LPC2378

I'm a newbie to eCos and I want to port eCos 3.0 to LPC2378. But i don't know how to do it.

I have read "Embedded Software Development with eCos" and it guide me that I have load Redboot to LPC2378 first and then, use Redboot command to load eCos. But I cann't load Redboot to LPC2378.

I have built Redboot with "eCos Configuretion Tool" and later I have redboot.img. then, I use "arm-elf-objcopy -O ihex redboot.img redboot.hex" command to convert img file to .hex file and then I use Flash Magic to load redboot.hex into LPC2378 but redboot doesn't work (I don't see anything on Hyper Terminal when I connect Hyper Terminal to LPC2378 board)

Do you have any experience in porting any other RTOS?

Note that porting an RTOS is really not a beginner's task!

Are you sure you are using the correct cross-compiler?
Is the .hex file programmed starting at address 0x0, where the processor starts to fetch instructions after boot? Or maybe it expects a bootloader to be present...? Have you followed the porting instructions? Debugged the result...?

I've never used eCos, but a very quick search found this:

http://en.wikipedia.org/wiki/ECos

And, of course, the eCos home page:

http://ecos.sourceware.org/

"I have read 'Embedded Software Development with eCos'"

But, surely, that is just a user guide?

For porting, shouldn't you be reading the Porting Guide?

http://www.embedded.com/story/OEG20011220S0059

The eCos FAQ has sections titled "Got Problems?" and "Support"

http://ecos.sourceware.org/fom-serv/ecos/cache/1.html - that would be the place to start
