启动流程
- 汇编文件 start.S 中定义了
bl602_start() 函数，相当于 ARM 核的 Reset_Handler()
- `bl602_start()` 最终调用 `bfl_main()` ，初始化一些列硬件和软件环境，最终创建 `aos_loop_proc()` 任务，并调用 `vTaskStartScheduler()` 启动 FreeRTOS 内核；
- 在 `aos_loop_proc()` 中初始化 easyflash 组件、VFS等模块，创建 `app_main_entry()` 最后删除自身这个任务；
- 在 `app_main_entry()` 最终调用用户空间的 `main()` 函数；
