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

[Gatien Gillon <ggillon@ulb.ac.be>]

I don't have a JTAG

When I compile I get a big image 835 kb wich is too big to send. what command emust I type to get a smaller image so I can send it to redboot : with load ymodem and then write it with fi wr to the ROM ?

Does anybody know the adresse of the EB55 board ?

(I'm really lost I'm quite a newby)
