How to change memory mapping on LPC11C14

Hi,

I am using my custome board based on LCP11C14.

I used LCP expresso and LPC open libraries.

In my application I have large data to display on GLCD.

Due to that I am getting below error.

How can I change memory mapping so that I can utilize MFlash32 to store initialize data?

From below logs 8KB is allocated for RamLoC8 and 32KB is for MFlash.

Can I increase size of RamLOC8? How?

 

Building target: lcd_test.axf

Invoking: MCU Linker

arm-none-eabi-gcc -nostdlib -L"C:\nxp\workspace\ws_lpc11C14\nxp_lpcxpresso_11c24_board_lib\Debug" -L"C:\nxp\workspace\ws_lpc11C14\lpc_chip_11cxx_lib\Debug" -Xlinker -Map="lcd_test.map" -Xlinker --gc-sections -Xlinker -print-memory-usage -mcpu=cortex-m0 -mthumb -T "lcd_test_Debug.ld" -o "lcd_test.axf"  ./src/cr_startup_lpc11xx.o ./src/crp.o ./src/lcd_test.o ./src/sysinit.o  ./liblcd/src/lcd.o   -lnxp_lpcxpresso_11c24_board_lib -llpc_chip_11cxx_lib
