I am following the instructions
(http://ecos.sourceware.org/docs-latest/redboot/at91.html) to the word
with no sucess. Here are my steps:

Here I start minicom so I can load redboot.srec (I even desperately
tried redboot.img/bin)
~/work/atmel/020606-ARM/install/bin$ minicom -o

After this step I set SW1 (on the EB40 board) to UPPER MEM then press
restart and nothing happens, meaning no output.
