Hello,

while dealing with custom bootloader we have to switch application to certain offset address.

Thus we have to move the address of the vector table.

While HSE values are supported to be customized vector table offset is not.

please add following lines to the system_stm32xxxx.c files:

/* &sharpdefine VECT_TAB_SRAM */

---> &sharpif !defined(VECT_TAB_OFFSET)

&sharpdefine VECT_TAB_OFFSET  0x00 /*!< Vector Table base offset field.

                                   This value must be a multiple of 0x200. */

---> &sharpendif

Thanks, Regards,

Adib.

They should just stop using the define, and get the linker to do this using a symbol for the Vector Table, it's what sane people do...

And it's not even a 

#ifndef VECT_TAB_OFFSET
#define VECT_TAB_OFFSET 0
#endif

:crying_face: And as it's not part of the template engine I can't even use that to fix this... -> Running patch as part of the make process it is....

It's stupid by design, people with any conception of how compilers/linkers work would have used a symbol from the outset. Defining things in multiple places is a recipe for failure. The linker in this situation determines the "built-at" address.
