Dear All,
Can anyone help me in solving this problem in IAR compiler.
The stack 'Stack' is filled to 92% (74 bytes used out of 80). The
warning threshold is set to 90%
Have a nice day.

First, it is not necessary a problem, it's just a warning as it hasn't
overflowed yet. You need to know what the stack is and how it is used to
understand what the warning means and if you need to do something about it and
what that would be.
But to answer your question:
You have a bucket. You have someone watching it. He gives you a warning when it's 90 percent full.
The watcher is sending you a warning because it is 92% full. What do you do if you don't want him to give you a warning?
Either increase the stack size (override the default 80 bytes), increment the treshold (or shut him up) or decrease the stack usage. You can do the latter by moving local variables to global ones, using smaller variables like chars instead of ints where allowed, or reduce function call nesting. Each time you call a function, local variables from the CALLING function are pushed into the stack. IAR has a very useful option where you can see which functions are presently on the stack (you can see the stack 'tree'). Don't remember where it is. Maybe View -> Stack?
Anyway, you first need to learn what the stack is.

Michael K.

Please don't set any limit the stack. Set it to auto.

Is there a way to set it to auto? Mine just says choose a number between 0 and
65535.
