TouchGFX error when I put a bigger image

Hello,

i can manage TouchGFX Designer with very basic objects such as an analog clock and a color background, and it works very well.

When i decided to insert a real image as background (720x720) it returns the following error during compilation:

arm-none-eabi-g++ -o "arlix3.elf" @"objects.list"  -l:libtouchgfx-float-abi-hard.a -mcpu=cortex-m7 -T"C:\Users\nikte\STM32CubeIDE\workspace_1.3.0\arlix3\STM32F767IGTX_FLASH.ld" --specs=nosys.specs -Wl,-Map="arlix3.map" -Wl,--gc-sections -static -L"C:\Users\nikte\STM32CubeIDE\workspace_1.3.0\arlix3\Middlewares\ST\touchgfx\lib\core\cortex_m7\gcc" --specs=nano.specs -mfpu=fpv5-d16 -mfloat-abi=hard -mthumb -Wl,--start-group -lc -lm -lstdc++ -lsupc++ -Wl,--end-group

collect2.exe: error: ld returned 1 exit status
make: *** [makefile:74: arlix3.elf] Error 1
"make -j4 all" terminated with exit code 2. Build might be incomplete.

So I thought it was a problem of the small internal flash memory. I wrote my own Quad SPI driver for W25Q256 FLASH memory, and i created a custom external loader for my custom board, which works very well with ST-LINK Utility. I can access to FLASH memory without problems.

But nevertheless the problem is always the same.

Do you know what is the problem? Thank you, Alberto.

Ok i fixed it, but another problem appeared.

Error in final launch sequence:
 
Failed to execute MI command:

Error message from debugger back end:

It was uploading to the external flash, while this errore comes out. However i can erase and see my external FLASH from STM32CubeProgrammer. One strange thing is that (when it is just erased) it has all 99999999 until 0x90000400, while over there are only FFFFFFFF.

Looking at log file i think the error comes from

[41.220] spawnCubeProgrammer():  Encountered Error when opening C:\ST\STM32CubeIDE_1.3.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_1.3.0.202002181050\tools\bin\STM32_Programmer_CLI.exe

Can i upload my .elf file directly from CUBEProgrammer? I see something strange, that the .bin file is 2 GB heavy!

And the second problem it returns is

Error: failed to download Segment[1]

I don't know if the problem is my external loader (which it allows tìme to write bin files and read from QUADSPI, however i read 9999999 in the first lines), or the .ld file of my Touchgfx application.

The .ld file for the creation of the external load is
