How to redefine the internal SRAM regions in MCUXpresso IDE?

Hi, I’m building the project with LPC54608J512 on MCUXpresso IDE.

The internal RAM is divided into:

SRAM0, SRAM1, SRAM2 and SRAM3 : 160kB starting from 0x20000000

SRAMX (RAM2)  - 32kB starting from 0x04000000 and

USB_RAM (RAM3) - 8kB starting from 0x40100000

I want to use e.g. SRAMX (32kB) as the main RAM for data, stack and heap and SRAM_0_1_2_3 (160kb) only for frame buffer of GUI (130kB).

I can see in the Memory configuration editor of MCUXpresso IDE the possibility to add, split or delete RAM areas, but I cannot see how to redefine the regions for usage as a “main” RAM area - for SRAMX  or USB_RAM (if I do not want to use it for USB).



Is it possible in MCUXpresso IDE?
