For example, to locate the stack at address 0x2000_6000:

PROVIDE(_vStackTop = 0x20006000);

Instead of editing the link scripts file, the stack offset change can be made inside the IDE:

1. Right-click on the project_name in the Project Explorer view.

2. Select Properties.

3. Click on C/C++ BuildSettingsTool Settings tabMCU LinkerTarget and input the desired stack

offset into the Stack offset field. This offset will occur from the top address of RAM, and the value must be

a multiple of 4. Figure 17 shows this dialog in the Precision32 IDE.

After changing either the custom linker script or IDE settings, clean and rebuild the project. View the map file for the

project to verify the stack location changed as desired.
