Change App start address in STM32F4 ( Bootloader USB + App)

[HHich.1]

Hello all,

I have a project using STM32F407 with 1MB of flash and it uses :

• USB Bootloader project ( start address 0x8000000)
• App project ( Start address  0x800C000)

I want to change the App start address to sector 4 ( 0x08010000)

From my understanding I have to change the following defines

 

In bootloader, tell the bootloader wher to find the app !

 

 

#define USBD_DFU_APP_DEFAULT_ADD 0x08010000U

 

In App, in its linker  (STM32F407VGTx_FLASH.ld)

 

FLASH (rx) : ORIGIN = 0x8010000, LENGTH = 720K

 

I tried the above settings but it didn't work ! App doesn't start

I read that I have to change vector table address aswell  system_stm32f4xx.c

So I added the offset of 16K 

 

 

#define VECT_TAB_OFFSET 0x4000

 

 

 

But this didn't work either,

 

Any solution for my basic issue ?

Why 16K if the address is 0x8010000 ? This is 64K.
