TMS320F280049C: [280049c] Out Of Memory(ram) Issue

Part Number: TMS320F280049C

Hello experts, I am seeking your assistance. I am currently working on embedded programming using the TI DSP 280049C MCU. The problem I am facing is a possible lack of RAM space. The .ebss section requires a size of 0x4A47. However, even if I use the entire currently configured RAMLS address, it seems like the capacity would be exceeded with only 0x001800 available. I am wondering if it is possible to combine and use the RAMGS area as well? I am not using DMA or CLA.

PAGE 1 :

BOOT_RSVD : origin = 0x000002, length = 0x0000F3 /* Part of M0, BOOT rom will use this for stack */
RAMM1 : origin = 0x000400, length = 0x000400 /* on-chip RAM block M1 */

RAMLS5 : origin = 0x00A800, length = 0x000800
RAMLS6 : origin = 0x00B000, length = 0x000800
RAMLS7 : origin = 0x00B800, length = 0x000800

RAMGS0 : origin = 0x00C000, length = 0x002000
RAMGS1 : origin = 0x00E000, length = 0x002000
RAMGS2 : origin = 0x010000, length = 0x002000
RAMGS3 : origin = 0x012000, length = 0x002000
