ANYONE USING STM32F105 BOOTLOADER SUCESSFULLY?

EZagr.1

Hello. i try to write simple bootloader that run simple program (blink with 1 led)

This works fine on stm32f103 but the same code not working on f105 :(

bootloader start from 0x08000000 and main app from 0x08008000

both program made in cube ide ()

code of bootloader

uint32_t appJumpAddress;

void (*GoToApp)(void);

appJumpAddress = *((volatile uint32_t*)(FLASH_USER_START_ADDR + 4));

GoToApp = (void (*)(void))appJumpAddress;

__set_MSP(*((volatile uint32_t*) FLASH_USER_START_ADDR));

GoToApp();

code of main app

while (1)

 {

 HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_12);

 HAL_Delay(1000);

 }

in system_stm32f1xx.c of main app i uncomment #define USER_VECT_TAB_ADDRESS and change #define VECT_TAB_OFFSET to 0x00008000U

then i build both projects and write with CubeProgrammer (booloader with in 8000000 and app in 8008000)

what the difference between 103 and 105 for bootloader?

P.S. i spend 3 days with this problem and tryed many examples of disabling,clearing, masking different registers and etc. Maybe some one have working example for f105?
