You mean the eCos-lib is 1.3 MB big, but you have to keep in mind that
not everything in the lib also is included in the elf-image you burn
into the flash. The file 'dprd' is your srec-image ready to burn it
into the flash memory - am I right? It already contains everything you
need, also all the eCos-stuff.

yes, as I already mentioned before, you can use the JTAG to programm the flash
