Running out of FLASH memroy (X-NUCLEO-GFX01M2 + Nucleo-H503RB)

[AnanD55_kmwt]

Hi Everyone, Happy New Year.
I have started working on this project and till now i have added 5 screens in the touchgfx, from touchgfx side the project is running fine on the simulator but it is not getting builded on the cubeIDE. I am running out flash memory.
so please help me how to resolve this issue.

C:/ST/STM32CubeIDE_1.16.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.200.202406191623/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: STM32H503RB-NUCLEO-GFX01M2.elf section `.rodata' will not fit in region `FLASH'

collect2.exe: error: ld returned 1 exit status

make: *** [makefile:98: STM32H503RB-NUCLEO-GFX01M2.elf] Error 1

"make -j4 all" terminated with exit code 2. Build might be incomplete.

Also i am building this project in Release mode. so is there any way to flash this code into SPI_FlASH as i have only 128 kb internal flash but the display flash is 8 MB.

Optimize level config for C and C++ ???

Assets in external flash ?

[AnanD55_kmwt]

Thanks for your reply.

Assets are kept in ext Flash only and can you please elaborate this Optimize level config for C and C++ as i am not aware of it?

try use higher value as you have now...

[AnanD55_kmwt]

I have this configuration

Ahhh set -O3 in both G++ and GCC

[AnanD55_kmwt]

still getting the same issue

Are you sure SAME? I dont see previous error... And manage your app is your job, what you ask?

Open memory details in App analyzer on your screenshot and locate issue...

Not actually i dont know why this error is occurring. also in memory details i see that most of the space in flash is occupied by .text region (112.4kb/128kb). 
I am using handleKeyEvent function for navigating and selecting the ui elements. i am wondering if this causing an issue?

is there any way of storing the code in SPI flash and access that. for this i have made changes in .ld file but the bootloader doesnt know about it.
