As far as I know no specific magic was used to turn on redboot at that 
time.  I do know that we only got gdb working reliably over the serial 
interface with it (not over net or multi-ice).  But I wasn't the 
person who played with redboot at that time so I can't say for sure 
the configuration wasn't altered.

Comes out of my head so don't shoot me if I forgot some steps.
You need to change CYG_HAL_STARTUP from RAM to ROMRAM (or ROM if you 
want to run from flash) in your ecos.ecc.  The executable you make 
has to be transformed in srec format using objcopy, and then you can 
load it with the ARM bootloader.

But if you are not sure about your application or ecos setup I wouldn't
recommend starting with this as you have no debugging support and you 
are thus responsible yourself for getting anything out of the system.
Do the diagnostic leds give any clue about where it stops working?

Joeri.
