Hi,

Im using threadx, in that i have defined a task in which i initialize my external flash memory regions 
i have a 116 byte structure which contains memory information

when i use this structure locally i get a never execute hardfault error where as when i move that variable to global i dont get hardfault
please note that the stack size of task is 6200 bytes

So have you tried increasing that - by at least 116 bytes ... ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

as you can see my stack is barely full only 2kb is used and yes i did try increasing it

What specifically is the nature of the Hard Fault, see registers, stack and instructions. 

If not a stack overflow, perhaps corruption or modifying out of bounds.

Failure at return?

Use for a DMA or IT routine and losing scope?
