http://www.t-firefly.com/doc/download/page/id/4.html

1. 安裝：RK驅動助手
2. 安裝：windows固件更新工具
3. 下載下傳：Ubuntu系統
4. 下載下傳：linux-sdk gpt源碼包

• 根據wiki設定rk3288進去maskrom
• 打開Android_tool

  

• 更新為ubuntu[選中固件，擦除flash，更新固件]

本地編譯版本

• build.sh腳本運作完成後，會将分區鏡像和統一固件update.img放在rockdev/目錄下，同時建立IMAGE/目錄備份。

燒寫本地image

• 

• 

• 燒錄成功 

  測試hdmi以及touch功能是否正常

  • 成功點亮，weston log以及kernellog關鍵如下

• 安裝vysor for ubuntu
  • www.vysor.io  linux包下載下傳起來挺吃力的，親測18.04版本ubuntu可基本正常使用。我已經上傳csdn：
    • https://download.csdn.net/download/u012839187/12302260

嘗試yocto的rk3288包，這個更加符合我目前的工作情況

# 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

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

      如果之後又想擷取完整曆史資訊，可以使用下面的指令：
      $ git fetch --unshallow
