hi, i want to set an offset value to vector table of my application for writing a custom bootloader.

i set it with VECT_TAB_OFFSET definition in thesystem_stm32f4xx.c file like following:

#define VECT_TAB_OFFSET 0x00004000

but i cant confirm it from map file. it still remaining like following:

__vector_table 0x08000000 Data Gb startup_stm32f4xx.o [1]

i think, it must be like this, right?

__vector_table 0x08004000 Data Gb startup_stm32f4xx.o [1]

where did i wrong? #vectortabl #stm32f4 #bootloader #rtfm #know-your-tools

You would need to also tell the linker where to place the firmware, via the scatter file, linker script, or target GUI

but i use IAR as IDE. so i have no scatter file.

And I'd know this from your original question how? Like I said with the 'OR', it can be in a number of places, the ''linker script/scatter file'' in IAR is the .ICF, there should also be options for the project via the GUI to set this, I'd presume.
