1052读写flash操作

经天纬地_659832

由于项目需要，我在RT1052上需要进行Flash的读写，如下是工程的link.lds文件，我把flexspi_norflash.、 fsl_flexspi.c和fsl_clock.c的相关函数操作放在了m_data 段，然后 调用FlexSPI_Init  进行初始化，但是板子还是一上电就重启，无法进入系统

如下是初始化代码
    int i = 0;
    int ret = 0;

    BOARD_ConfigMPU();
    BOARD_InitPins();
    BOARD_BootClockRUN();

    NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4);
    SysTick_Config(SystemCoreClock / TICK_PER_SECOND);

    InitBoardMemory((void *)HEAP_BEGIN, (void *)HEAP_END);

#ifdef BSP_USING_LPUART
    Imxrt1052HwUartInit();
#endif

    InstallConsole(KERNEL_CONSOLE_BUS_NAME, KERNEL_CONSOLE_DRV_NAME, KERNEL_CONSOLE_DEVICE_NAME);
    KPrintf("\nconsole init completed.\n");
    KPrintf("board initialization......\n");

    KPrintf("board init done.\n");
    KPrintf("start kernel...\n");

    FlexSPI_Init();




下面是上电后串口打印的内容
board initialization......
board init done.
onsole init completed.
board initialization......
board init done.
onsole init completed.
board initialization......
board init done.
onsole init completed.

有遇到过这种问题的朋友吗
