I am using TouchGfx on STM32H747I-DISCO board. My final binay size is 2.13 GB

[shiv50084]

Default Image Configuation setting is :

Framework Features:

Size of .bin file 

Touch Gfx setting in IOC file:

 

I also followed the link:

https://community.st.com/t5/stm32-mcus-products/generated-binary-file-size-is-too-large-2-3gb/td-p/300719

 

But still size is 2.13 GB.

 

Can you please help me to reduce the size of binary?

Don't use a .BIN to describe two regions with large separation within the ARM's 4GB address space.

Use a .HEX, or divide into two or more .BINs describing the 0x08000000 and 0x90000000 regions separately.

I am using this command 

arm-none-eabi-objcopy.exe -O binary --only-section=ExtFlashSection "${BuildArtifactFileBaseName}.elf" ExtFlash.bin;arm-none-eabi-objcopy.exe -O binary --remove-section=ExtFlashSection "${BuildArtifactFileBaseName}.elf" STM32F746.bin

 

From mentioned link in query.

 

I need bin file for FPU. How can I create different  file from hex?

[Tesla DeLorean]

I don't expect the functionality of objcopy has changed. Review the command documentation and man page.

Check you're using the same/correct naming for the sections in the .ELF file. Check the .LD and what's described in the .MAP file

In project settings uncheck bin file create.... you have hex ok.

Hello @shiv50084 ,

 

We made a video about reducing flash size : How to TouchGFX: Save flash memory 

You could also check your compiler setting to reduce size (-Os for size optimization in GCC).

 

I hope this helps. :smiling_face_with_smiling_eyes:
