1. 安装：RK驱动助手
2. 安装：windows固件升级工具
3. 下载：Ubuntu系统
4. 下载：linux-sdk gpt源码包

• 根据wiki设置rk3288进去maskrom
• 打开Android_tool

   

• 升级为ubuntu[选中固件，擦除flash，升级固件]

本地编译版本

• build.sh脚本运行完成后，会将分区镜像和统一固件update.img放在rockdev/目录下，同时创建IMAGE/目录备份。

烧写本地image

•  

•  

• 烧录成功 

  测试hdmi以及touch功能是否正常

  • 成功点亮，weston log以及kernellog关键如下

• 安装vysor for ubuntu

  • www.vysor.io  linux包下载起来挺吃力的，亲测18.04版本ubuntu可基本正常使用。我已经上传csdn：

    • https://download.csdn.net/download/u012839187/12302260

 

尝试yocto的rk3288包，这个更加符合我目前的工作情况

# default Yocto/Pyro release for Rockchip 
repo init --repo-url=https://github.com/rockchip-linux/repo --no-clone-bundle  -u https://github.com/rockchip-linux/manifests -b yocto -m pyro.xml

#RK3288/Release
repo init --repo-url=https://github.com/rockchip-linux/repo --no-clone-bundle -u https://github.com/rockchip-linux/manifests -b master -m rk3288_linux_release.xml

 

1. repo init --repo-url=https://github.com/rockchip-linux/repo --no-clone-bundle -u https://github.com/rockchip-linux/manifests -b master -m rk3288_linux_release.xml
2. repo sync -c --no-tags

   1. 1.error: RPC failed; curl 56 GnuTLS recv error (-54): Error in the pull function.

      repo init --depth=1
      如果之后又想获取完整历史信息，可以使用下面的命令：
      $ git fetch --unshallow
