stm32 and jump to function

Hi. Iì'm trying to implement the jump to function.
So my stm32 microcontroller has got 2 firmwares.
The first is located at address 0x08000000 and the second is located at address 0x08008800.
Using the st flash utility I have verified that the address 0x08000000 contains the first firmware and the address 0x08008800 contains the second firmware.


The jump to function is this


typedef void (*pFunction)(void);
void cmd_Jump_To_Application(uint32_t start_Address) {
    uint32_t addressToJump = *(__IO uint32_t*) (start_Address + 4);
    pFunction Jump_To_Application = (pFunction) addressToJump;
    __set_MSP(*(__IO uint32_t*) start_Address);





but the second firmware never run.
That it is wrong?
