After a code is built,how and where can i find out the amount of Flash memory occupied by Stack and Program code?

How to identify the amount of heap memory available?

At the end of a build, the size of code, data and bss is displayed.
Flash = code+data
RAM = data+ bss

There is no way to determine the amount of stack used. The stack used depends on:
- how many nested functions are called
- how much recursion you use
- how many nested interrupts can occur
- how any locals you use in each function
- etc

Sorry, but this is not something that we can tell you - you have to work it out yourself. Did you try the example provided by NXP? That will give you an *ESTIMATE* of your stack usage.

You may find the example

at ( http://ics.nxp.com/support/lpcxpresso/ ) useful in measuring Stack/Heap usage.
