v821板子来源见贴:https://whycan.com/t_12383.html
1、硬件调试：
      收到板子，焊上flash之后，兴奋地将板子usb连上电脑，结果pc愣是半天没响应。第一反应就是板子莫非被静电打坏了?量了板子电压只有5v，其他引脚都没电压，看了原理图之后发现电源前还接了个没焊的充电管理芯片，直接飞线短接，再次插上usb，发现板子usb还是没识别到，这次真饶头了。最后看原理图量下其他引脚电压发现没有，再仔细对照板子，发现3个2.2uh电感没焊。缺啥补啥，到时还是不行，就打算把板子退回去了：)。焊上三个电感，重新插入usb，电脑终于识别到了。附上板子照片:
2、SDK编译及烧写
1)、设置编译环境:
root@glxu:/home/glxu/v821/tina-v821-release# source build/envsetup.sh
NOTE: The SDK(/home/glxu/v821/tina-v821-release) was successfully loaded
load openwrt... ok
Please run lunch next for openwrt.
load bsp...ok
root@glxu:/home/glxu/v821/tina-v821-release#
2)、选择板配(选择v821-avaota_f1-tina):
root@glxu:/home/glxu/v821/tina-v821-release# lunch
You're building on Linux
Lunch menu... pick a combo:
     1  v821-aiglass-tina
     2  v821-avaota_f1-tina
     3  v821-ipc-tina
     4  v821-perf2b_fastboot-tina
     5  v821-perf2b-tina
     6  v821-perf2_fastboot-tina
     7  v821-perf2-tina
     8  v821-sc1745v-tina
     9  v821-ver1-tina
Which would you like? [Default v821-avaota_f1]: 2

3)、直接编译并打包固件
root@glxu:/home/glxu/v821/tina-v821-release# mp

...

4)、烧写固件
打开PhoenixSuit,短接FEL,插上usb升级。静待板子烧写完成。烧写完重新上电完，进入板子如下:

至此板子第一阶段调测完成！
