--- Quote Start --- How many Jtag-Uarts are needed, if I use two cpus?[/b] --- Quote End --- None. You don't need a JTAG uart to get uClinux running on a CPU. I suppose you also can use one or two. The "NIOS2 -terminal" program supports an "instance" paramter that I think is used to distinguish between several JTAG UARTS on the same JTAG interface. <div class='quotetop'>QUOTE (babysnow @ Jul 28 2009, 03:59 AM) <{post_snapback}> (index.php?act=findpost&pid=23293)</div> --- Quote Start --- The purpose of my multiprocessor project is to do paralell working.A uclinux system with several piece of working programs.

A more sophisticated design with one Linux system and a simple system as coprocessor usually is much more viable. -Michael
