How to activate a program from non-default flash memory address

Working environment: Windows 11, uVision v5.39.0.0 Community Edition, NUCLEO-F429ZI evaluation board, STM32CubeIDE 1.14.0.

I need to have two programs in STM32 board flash memory. The first one (loader) starts from default flash address 0x8000000. The second program (application) is downloaded to another flash memory address 0x8060000 (sector 7), and can start from this place, when properly activated.

This functionality is already implemented using STM32CubeIDE. I have app_stm prototype, built with STM32CubeIDE, which just makes a LED animation, nothing else. By changing some code:

FLASH (rx)      : ORIGIN = 0x8060000, LENGTH = 2048K
SCB->VTOR = 0x08060000 | VECT_TAB_OFFSET;

I can build app_stm.bin file. Using CubeMXProgrammer, I can download this file to the board address 0x8060000. Another STM32CubeIDE program, loader_stm, runs from default address. Immediately upon start, it executes this function:


static void ActivateApplication()
    typedef  void (*pFunction)(void);
    pFunction JumpToApplication;
    uint32_t JumpAddress;

    SysTick->CTRL = 0x0; // Disables SysTick timer and its related interrupt

    JumpAddress = *(__IO uint32_t*) (FLASH_APPLICATION_ADDRESS + 4);
    JumpToApplication = (pFunction) JumpAddress;

    __set_MSP(*(__IO uint32_t*) FLASH_APPLICATION_ADDRESS);

ActivateApplication function is successful, app_stm program starts.

Now I need to implement loader functionality using Keil MDK. So, I make loader_keil application, which executes the same ActivateApplication function (app_stm program is still waiting for activation at 0x8060000). The result is: program stops, app_stm is not activated.

Debugging loader_keil, I see that after JumpToApplication() call it goes to HardFault_Handler.

So, the question is: how to activate another application from Keil MDK program, as it can be done from the program, built in STM32CubeIDE?
