Nope, until 0x08009974 there are no gaps, no "FFFF" is written before the one you see in the picture. I checked

Yes, but as I said I looked in the flash memory with the STM32 Programmer, and as you can also see I have code until 0x08009974, which is page 19 of the Flash memory. So the actual occupied memory size is more than 38 kB (each page is 2 kB in dual b...

My problem is that the code I am actually flashing in the microcontroller is 38.37 kB, which I confirmed by also opening the flash memory with STM32CubeProgrammer. I don't understand why I am flashing a file that is double the size of my actual code...

Sure, here it is

Okey so I understood what the build analyzer is showing. BUt where do the other 20 kB of code come from? Is there anyway to reduce this amount?
