re:Re: [ECOS] eCos Romable ? (on AT91EB55)

I'm kind of lost
Which part do I write in the flash ?
?
Loading section .rom_vectors, size 0x40 lma 0x2008000
Loading section .text, size 0x13370 lma 0x2008040
Loading section .rodata, size 0x1184 lma 0x201b3b0
Loading section .data, size 0x458 lma 0x201c534
Start address 0x2008040, load size 84364
?

What I'd like to do : keep Redboot on the second half of the flash write my image in the first part of the Flash is it possible ?
