got it working !!!
it seemd that 3.3v suply from the FTDI cable wasnt working corectly...
as soon as i figured the mega 1284 pins corectly (for cs and cse) and powered from 5v works ok

with a minor glitch sometimes bouth modules initialize ok but if i switch one to transmit role all i get is timeout, if i go on the other module and switch it to transmit works ok, swap again and the other module works too on transmit... kinda weired got to look into this anyway
later edit : its like this, all connected ok
module 1 (on mega1280) on transmit module 2 (on mega 1284) on recieve works fine for minutes now
if i reset module 2 i will get timeouts even afther its restarted
i switch module 2 on transmit and back on recieve (withouth doing anithing to module 1) they begin to work again:

if i reset module 1 and switch it back to transmit all works corectly so its something with the module on atmega 1284 or my wiring or something i dont know if you can sugest something i would greatly apreciate it.
