How status of boot0 pin to jump application from bootloader

[samir oulahrir]

Hi everybody,

I'm trying to implement IAP to jump from bootloader to my application on stm32h743 target.

I m trying to use example code STM32H743-EVAL from ST without success.

I think, i set correctly both linker file, remmaping of VECT_TAB_OFFSET etc.

My question is, what should be the status of boot0 pin ? In my case, it is connected to ground.

Do you have any idea or suggest ?

Thank you

Samir

Hi,

I am back and despite the change of linker script, there is no effect.

I dont understand why when i change end of RAM @0x2001FFFC, my APPLICATION_ADDRESS value is still stored @0x20020000 !
