Bootloader Jumps Successfully But Firmware Doesnt Start

Question

Im trying to start the firmware located at address 0x08019000 inside my Flash, but even after making a successfully jump to the address, the firmware doesnt respond.

Im using the HSDatalog firmware from ST, which can be downloaded from github here. As microcontroller i use the STEVAL-STWINKT1B evaluation board with 2MB FLASH and 640KB RAM. My bootloader is successfully jumping to each flashed firmware that i use in my project, hence the it's code is not an issue. However, the firmware from ST seems "stuck" after i get to a task scheduler loop inside it and i can't understand why. Its main looks like this

int main(void) {
    HAL_Init();

    SystemClock_Config();

    /* Enable Power Clock*/
    __HAL_RCC_PWR_CLK_ENABLE();
    HAL_PWREx_EnableVddUSB();
    HAL_PWREx_EnableVddIO2();
    BSP_Enable_DCDC2();

    OTA_Verify_Current_Active_Bank();

    /* Configure the Battery Charger */
//  BattChrg_Init(); not needed

    /* Configure Power Voltage Detector(PVD) to detect if battery voltage is low */
//  PVD_Config(); not needed

    /* Configure DEBUG PIN and LED */
    BSP_DEBUG_PIN_Init_All();
    BSP_LED_Init(LED_GREEN);
    BSP_LED_Init(LED_ORANGE);
    __HAL_RCC_GPIOA_CLK_ENABLE();

    /* Initialize srand() using STM32 TRNG peripheral */
    RND_Init();

    HSD_JSON_set_allocation_functions(HSD_malloc, HSD_free);

    /* Start USB */
    MX_USB_DEVICE_Init();
    HAL_Delay(100);

    HSD_DeviceDescriptor_Init_t deviceDescriptorInit;

    /* Set default device description */
    strcpy(deviceDescriptorInit.alias, "STWIN_001");
    strcpy(deviceDescriptorInit.model, "STEVAL-STWINKT1B");
    strcpy(deviceDescriptorInit.partNumber, "FP-SNS-DATALOG1");
    strcpy(deviceDescriptorInit.URL, "www.st.com/stwin");
    strcpy(deviceDescriptorInit.fwName, "FP-SNS-DATALOG1_Datalog1");
    strcpy(deviceDescriptorInit.bleMacAddress, "00:00:00:00:00:00");
    char tmp1[6] = {
    HSD_VERSION_MAJOR, '.',
    HSD_VERSION_MINOR, '.',
    HSD_VERSION_PATCH, '\0' };
    strcpy(deviceDescriptorInit.fwVersion, tmp1);
    set_device_description(&deviceDescriptorInit);

    /* Populate the sensor database and enable all sensors */
    Create_Sensors();

    /* Initialize tags */
    HSD_TAGS_init(COM_GetDevice());

    /* USER Button initialization */
    BSP_PB_Init(BUTTON_USER, BUTTON_MODE_EXTI);
    BSP_PB_PWR_Init();

    /* Sensor Manager initialization */
    SM_Peripheral_Init();
    SM_OS_Init();
    Peripheral_MSP_Init_All();

    /* SD card Manager initialization */
    SDM_Peripheral_Init();

    /* Initialize sensors and SD card threads */
    Peripheral_OS_Init_All();
    SDM_OS_Init();

    /* Initialize and allocate AutoMode thread */
    g_pxAMtaskObj = AMTaskAlloc();
    AMTaskInit(g_pxAMtaskObj);

    /* initialize and allocate BLE thread */
#if (HSD_BLE_ENABLE == 1)
    BLE_CM_OS_Init();
#endif
    /* Start scheduler */
    **osKernelStart**();

    while (1)
        ;

}

• Bootloader program here(Credit to Akos Pasztor)
• Bootloader usage in main.c here

Im invoking the Enter_Bootloader function after i successfully mounted an FatFS formated SD card. That function flashed my .bin onto the FLASH beginning at a specified address. Afterwards im jumping to the application using the Bootloader_JumpToApplication function.

Has anyone ideas why the firmware may get stuck? And has anyone used this firmware together with a bootloader to share his experience?
