How to copy the font and image section to binary file?

I am trying using NAND flash to storage the setions, but don`t know how to dump these sections to a binary file, https://support.touchgfx.com/docs/development/scenarios/using-non-memory-mapped-flash shows command "arm-none-eabi-objcopy.exe --dump-section ExtFlashSection=images.bin TouchGFX/build/bin/target.elf" to generate it, so if I want to dump images alone with fonts, how to write the cmd and config on STM32CubeIDE?

So do you have the idea? The start address of my SDRAM after FMC configuration is 0xC0000000, so if I configure the "post build" as 

arm-none-eabi-objcopy.exe -O binary --only-section=ExtFlashSection "${BuildArtifactFileBaseName}.elf" images.bin;
arm-none-eabi-objcopy.exe -O binary --remove-section=ExtFlashSection "${BuildArtifactFileBaseName}.elf" ${BuildArtifactFileBaseName}.bin;

and then the "{project}.bin" would be over 1GB on my disk. Does anyone konw how to write the link script file to generate the binary file so that I can upgrade the nand flash via UART?
