硬件设备
- 主板： EASY EAI Nano（送的），主控IC：RV1126
- 屏幕： 晶尚显示10.1寸MIPI屏幕，显示IC：ILI9881C
- 触摸： 晶尚显示10.1寸MIPI屏幕，触摸IC：GT9271
电路设计
主板的40pin接口线序和屏幕接口线序不一样，需要自己画转接板，将二者线序对上即可。注意mipi走线规范和阻抗匹配。
屏幕移植
厂家资料会给出相应的规格书和相关初始化代码，但是mipi屏幕在安卓上用的比较多，初始化代码基本上都是安卓内核的。需要我们自己对照厂商代码自行修改RV1126设备树相应的初始化序列。

在kernel目录下执行此命令：./build-kernel.sh && adb push ./tmp/modules.tar.gz /userdata && adb shell "tar -xf /userdata/modules.tar.gz -C /usr"
待一切ok后，按住boot键+短按电源键重启到boot模式，执行以下命令：sudo ./upgrade_tool di -boot ./kernel/boot.img
烧录完成后需要手动按一下电源键复位开机。
如无问题，开机会正常显示开机logo.
