打开Arduino IDE的\hardware\arduino\boards.txt文件,并添加以下代码

注意原有的IDE环境可能会影响R2这个版本的编译环境，所以可以尝试用一个没有装过IDE的电脑进行烧录，或者把原来电脑上的开发环境删掉，用R2烧录。该软件可以到浏览器下载，我在官网是没有找到的。

打开Arduino IDE的\hardware\arduino\boards.txt文件,并添加以下代码

解决方案，arduino 1.0.5-r2版本

arduino 添加
https://mcudude.github.io/MiniCore/package_MCUdude_MiniCore_index.json
然后添加开发板支持，选择168 再选 168P
然后用其他arduino 或者 avr下载器烧录 bl

提示签名不一样，怎么办
