制作 img 烧写镜像

注意：boot 内核与文件系统一起编译。

步骤一：首先需要修改 lichee\tools\pack\chips\sun8iw11p1\configs\OK40i\sys_config1024x600.fex文件，

步骤二：配置

# cd /root/workspace/allwinner/A40i/bsp/lichee/

#./build.sh config

Welcome to mkscript setup progress

9. 1024x600mipi_v1

10. 1280x800_v1

Choice: 3

步骤三：root@ubuntu:~/workspace/allwinner/A40i/bsp/lichee# vi .buildconfig

  1 export LICHEE_CHIP=sun8iw11p1
  2 export LICHEE_PLATFORM=linux
  3 export LICHEE_KERN_VER=linux-3.10
  4 export LICHEE_ARCH=arm
  5 export LICHEE_BOARD=OKA40i_C
  6 export LICHEE_BUILD_ROOT=buildroot-201611
  7 export LICHEE_GNUEABI=gnueabihf
  8 export LICHEE_QTVER=5.9.0
  9 export LICHEE_RESOLUTION=1080P
将其按如图所示进行修改。

步骤四：编译#./build.sh

步骤五：打包#./build.sh pack

这时pack目录下打包生成的镜像实际的分辨率就是1080P的。
