Hi  Ralf, thanks for your reply. Sorry but probably there is something I can't 
understand. You say that in the simpad there is a "standard bootloader". But I 
can't complete the procedure you suggest. How I'm supposed to start the serial 
download?? What does it means "press the right of both available keys..." ?

All I can do is access the "unusefull" menu by pressing the ESC keys. And I 
haven't any chance to upload via serial interface. I could try to do it if I 
had a NE2000 PCMCIA Card, but unfortunately I missed it!

I think the only chance is go with JTAG cable at this point!

Thanks to all

Cheers

Massimo
