    Hello,

    I also tried ceating software using NIOS SBT for Eclipse using GUI.

    When I import the .sopcinfo file and process further, it says "Failed to execute: ./create-this-bsp --cpu-name core_top --no-make".

    Need Help. Please suggest.

    Hello I have solved the issue and issue was with the addressing of peripherals in Qsys.

    Now, I have been hardly trying to run the 3 cores simultaneously but I am not able to do so.

    I have 3 cores and i just programmed the three cores to continuously print "Hello World" with some delay. When I download code in 1st core, it starts printing successfully. But when I do it for 2nd core, the 1st core stops printing. Why is it so.

    Ideally, 1st core should print as soon 2nd core is done printing once.

    I have managed the timing to print so that they don't overlap while printing the same time.

    Help is really appreciated
