linker cmd file: (HIGH) specifier

Mathieu Houde

In a cmd linker file, what is the purpose of the operator "(HIGH)" used for the allocation of the .stack to RAM?

Here is a copy-paste of my cmd file:

SECTIONS

{
.bss : {} > RAM /* GLOBAL & STATIC VARS */
.data : {} > RAM /* GLOBAL & STATIC VARS */
.sysmem : {} > RAM /* DYNAMIC MEMORY ALLOCATION AREA */

.stack : {} > RAM (HIGH) /* SOFTWARE SYSTEM STACK */

[...]

Thank you

The HIGH specifier can be applied to any section. It instructs the linker to place the section as close to the higest-valued address in that memory as possible. By default, the linker will place sections at the lowest-valued address of a memory first.
