Hi,

I created a blank project for STM32U5G9J-DK2 and in process of programming the board, GfxDesigner generates 400MB file intflash.elf. With GfxDesigner 4.24.1 it is 4MB.

Why 4.26.1 generates  intflash.elf so large ? A bug ?

Thanks

Thank you for that @Osman SOYKURT . So it is not some problem with my install/machine

I am actually not using GfxDesigner flash/build functionality - only tried it out of curiosity and thought I let you know about this file size issue.
