stm32 m0 and firmware relocation

Posted on May 24, 2018 at 22:03

According with the example these lines of code

    #define APPLICATION_ADDRESS     (uint32_t)0x08004000

    volatile uint32_t *VectorTable = (volatile uint32_t *)0x20000000;

    uint32_t ui32_VectorIndex = 0;

    for(ui32_VectorIndex = 0; ui32_VectorIndex < 48; ui32_VectorIndex++) {

        VectorTable[ui32_VectorIndex] = *(__IO uint32_t*)((uint32_t)APPLICATION_ADDRESS + (ui32_VectorIndex << 2));

    }

    __HAL_RCC_AHB_FORCE_RESET();

    __HAL_RCC_SYSCFG_CLK_ENABLE();

    __HAL_RCC_AHB_RELEASE_RESET();

    __HAL_SYSCFG_REMAPMEMORY_SRAM();

work in my SMT32F091RCTx demo board but only with

CubeMX -> SYS -> TimeBase Source -> SysTick

If I chane it in CubeMX -> SYS -> TimeBase Source -> TIM1

the relocated firmware doesn't start.

What have I to do in order to have my relocated firmware working?
