--- Quote Start --- 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.[/b] --- Quote End --- But, in the SOPCBuilder, if a JTAG-UART module is added, then it can only be connected to ONE cpu. And I have made a test that if use only one jtag module in the SOPCBuilder, then the cpu without connection with jtag cannot worked. <div class='quotetop'>QUOTE </div> --- Quote Start --- I don't suppose it makes much sense to have two CPUs run two separate Linux OSes on the same Avalon bus, as the bus arbitration and queuing memory accesses will slow down both a lot. A more sophisticated design with one Linux system and a simple system as coprocessor usually is much more viable.[/b] --- Quote End --- I mean several programs without system, and a uclinux system. Is there any method to make the programs running paralelly?
