bootloader and rtx problem

I wrote a simple bootloader program (doesn't do anything but jump to the application code in flash once a timer expires) and I am having trouble getting rtx to work in the application code. It gets to a point in os_sys_init()'s assembly code where it will stick. If my application without rtx,it do work ok.

I am using the stm32f429zi m4 chip.

This is bootloader code.

static void JumpToApp(void)
{
    if (((*(__IO uint32_t*)ApplicationAddress) & 0x2FFD0000) == 0x20000000)
    {
        /* Jump to user application */
        m_JumpAddress = *(__IO uint32_t*) (ApplicationAddress + 4);
        JumpToApplication = (FunVoidType) m_JumpAddress;
        /* Initialize user application's Stack Pointer */
        __set_MSP(*(__IO uint32_t*) ApplicationAddress);
        __set_PRIMASK(1);
        JumpToApplication();
    }
    Uart1SendSyc("JumpToApp Failed!\r\n");
}

This is appliction code.

int main(void)
{
    NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x10000);
    LED_Init();
    while(1)
    {
        STM_EVAL_LEDToggle(LED4);
    }
}

this is .s file.
; Vector Table Mapped to Address 0 at Reset AREA RESET, DATA, READONLY EXPORT __Vectors EXPORT __Vectors_End EXPORT __Vectors_Size

What can i do for Vector ?
I am sorry for my english level..
I hope you can understand.
