极客社区对于开发环境搭建,源代码下载、编译、xflash下载、运行都给出了详细的说明,我这里只是照着做一遍。
一)ubuntu系统安装,本着一切一样的原则,这次自己安装了开发板要求的ubuntu版本ubuntu14.04 64位。

然后是install一些必须的库文件。
 
二)源代码下载方法:可以任选一种,注意编译前安装要求将kernel和sla中的代码正确拷贝。

  1. 1. AOSP
  2. repo init -u   https://android.googlesource.com/platform/manifest   -b android-6.0.0_r1
  3. Repo sync –j16
  4. 2. Linux
  5. https://github.com/helio-x20/linux/tree/helio-x20
  6. 3. SLA
  7. https://builds.96boards.org/releases/helio-x20/mediatek/aosp/latest/
  8. 目录下的mediatek-x20-aosp-16.10-source.tar.xz文件(解压缩后会有SLA.tar.gz)。
  9. 编译方案:
  10. 1、将AOSP代码解压(如果是repo获得可以忽略此步骤)
  11. 2、获取Linux代码后mv到AOSP目录下重命名为kernel-3.18
  12. 3、解压开SLA,覆盖相应文件
  13. 即可获得全套可以编译X20-Board代码。
  14. 国内用户的福音
  15. 你还在为翻墙而烦恼吗?百度云Link来啦。
  16. 1、AOSP
  17. 链接: http://pan.baidu.com/s/1boAZqJt 密码:mooh
  18. 2、Kernel
  19. 链接: http://pan.baidu.com/s/1o8IuBUU 密码:9ys6
  20. 3、SLA
  21. https://builds.96boards.org/releases/helio-x20/mediatek/aosp/latest/
  22. 目录下的mediatek-x20-aosp-16.10-source.tar.xz文件(解压缩后会有SLA.tar.gz)

复制代码

三)源代码编译
 
 

 
 
 
将近3个小时,不能使用小型机每次完全编译android源代码的时间够长啊。
四)更新系统并运行
How-To-Download-By-Xflash.pdf文档说的很清楚,仔细参照文档来做应该没有问题。下面是更新的全部log。

  1. F:\MediaTekX20\mediatek-x20-aosp-16.10\Images\X-Flash\xflash\bin\win>xflash.exe
  2. enter-fastboot F:\MediaTekX20\mediatek-x20-aosp-16.10\Images\X-Flash\xflash\bin
  3. win\FES\MT6797_Android_scatter.txt
  4. START.
  5. wait for device.
  6. connect boot rom.
  7. boot from preloader.
  8. download required partition images.
  9. #1 write to lk
  10. #2 write to logo
  11. #3 write to tee1
  12. jump to: tee1
  13. END.

系统成功后系统会自动进入系统,我这里没有触摸屏,所必须使用usb鼠标,所以更新完成后需要断电设置usb的模式。
https://bbs.alpha-star.org/hardware/helio-x20-development-board-usb%E9%80%9A%E9%81%93%E5%88%87%E6%8D%A2这个帖子说的很清楚,照着做就是。
 
注意:需要下载的时间时候将3拨到红线方向,需要使用usb鼠标的时候将3拨到黄线方向。
这里吐槽一下,这种方式比那种按住某个按键(比如声音+按键)后可以进入fastboot的方式可操作性差了许多!
 
 
 
看一下设置的信息,验证运行中的系统是我们编译的img。
下面会先加载一个驱动到Kernel中,熟悉一下DTS方式下驱动如何在Android内核中编译和加载,为后面添加USB摄像头驱动做准备。
