NIOS executes main() function repeatedly without use of any finite/ infinite loop

Thanks a lot sir Anand

Here I am attaching qsys filtering the clk and rst connections.

I cannot understand why the system is giving this problem. Actually it is not looping rather it is executing/ entering the main () repeatedly. Your point is worth understanding, NIOS may be is resetting and therefore re-executing the main function. But I cannot figure out where it is lacking.

Thanks
