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
