Setting the Stack Size for a User-Space Application Print

 

This application note explains how to set up the stack size for a user-space application.

The stack size can be changed using the arm-uclinuxeabi-flthdr utility:

[psl@ocean app]$ arm-uclinuxeabi-flthdr -h
usage: arm-uclinuxeabi-flthdr [options] flat-file
Allows you to change an existing flat file


-p : print current settings
-z : compressed flat file
-d : compressed data-only flat file
-Z : un-compressed flat file
-r : ram load
-R : do not RAM load
-k : kernel traced load (for debug)
-K : normal non-kernel traced load
-s size : stack size
-o file : output-file
(default is to modify input file)
