    Did you add the jtag uart component to your SOPC builder project? It isn't in the list.

    The standard C functions like printf() and scanf() can be used to interact with the console.

    if in your software you add printf() calls, it will display something in the nios console. For the other way round, what you have to type in the console really depends on your software.

    may be the simulation takes more time than 800 us to enter to my main and do the printf "hello word"
