Functions are not getting called even if they are called in Nios II S/W Design/Code

Hi all,

I am new to NIOS but I am trying to learn it. I have written a code, which is having multiple functions, some of the functions are calling other functions. Now here the problem starts, as I am calling other functions from inside of another function, many times the called functions are not getting called or executed. This I have completely verified by observation in the Signal Tap(I am Using PIOs).

For Example: There is a Write Function, One Read Function and a Delay Function. Whenever I am calling Delay Function inside a Write/Read Function, it is not getting called. I don't know the reasons of it but I am attributing it to Stack Overflow or Usage of 100MHz clock in NIOS.

Please help me in finding the reasons for it and a possible solution.

Regards,
