+ * @defgroup group_SystemInit System Initialization
+ *
+ * @brief System initialization procedure.
+ *
+ * When RT-Thread operating system starts up, the basic operating system facility
+ * initialization routines must be invoked.
+ *
+ * The suggested initialization sequence is:
+ *
+ * - initialize device hardware
+ * rt_hw_board_init();
+ *
+ * User can put the low level hardware initialization in this function, such as
+ * DDR memory setting, pinmux setting, console device setting etc.
+ *
+ * - show version
+ * rt_show_version();
+ *
+ * - initialize timer system
+ * rt_system_timer_init();
+ *
+ * - initialize system heap memory
+ * rt_system_heap_init(__bss_end, __end_of_memory);
+ *
+ * - initialize module system
+ * rt_system_module_init();
+ *
+ * - initialize scheduler system
+ * rt_system_scheduler_init();
+ *
+ * - initialize application
+ * rt_application_init();
+ *
+ * - initialize system timer thread
+ * rt_system_timer_thread_init();
+ *
+ * - initialize idle thread
+ * rt_thread_idle_init();
+ *
+ * - start scheduler
+ * rt_system_scheduler_start();
