1,启动流程：
bootload->main(8710SDK)->aosmaintask->application->application_start
创建项目出现如下错误：
aos create project -b esp8266 -t blink_demo -d tmp blinkapp
[AliOS-Things] ERROR: "python" returned error code 1.
[AliOS-Things] ERROR: Command "python /home/xy/AliOS-Things/build/scripts/gen_newproject.py

2，开发板点灯程序编写
一款方便阅读代码的工具 —source insight，使用方法如下：
https://www.cnblogs.com/andy-songwei/p/9965714.html
按mk3080开发板LED灯IO口进行配置
编写blink_demo.c如下：

#include "aos/kernel.h"
#include "ulog/ulog.h"

gpio_dev_t led_red;
gpio_dev_t led_green;
gpio_dev_t led_blue;

{

led_blue.config = OUTPUT_PUSH_PULL;
/* configure GPIO with the given settings */
// hal_gpio_init(&led_nucleo);
hal_gpio_init(&led_red);
hal_gpio_init(&led_green);
hal_gpio_init(&led_blue);
sys_itag_off();//关闭掉PA14,PA15的jtag功能
while (1)
{
/* Insert delay 1000 ms */
aos_msleep(1000);
printf(" toggle led \n");
// hal_gpio_output_toggle(&led_nucleo);
hal_gpio_output_toggle(&led_red);
hal_gpio_output_toggle(&led_green);
hal_gpio_output_toggle(&led_blue);
}
return 0;
}
aos make 编译完成：

root@tianmao-virtual-machine:/tmp/blinkappc/out/blinkappc@esp8266/binary# 路径下生成
blinkappc@esp8266.bin
使用image tool烧录工具进行烧写：
将 blinkappc@esp8266.bin 拷贝到共享文件夹下
用跳线将PA30(TX2)和GND短接起来。
download–>复位键–>拔掉跳线 ，烧写完后复位一下，看开发板灯的闪烁情况。
