根据教程视频中的通用串行总线部分，我的电脑上并没有显示cklink-lite是不是这个问题？

Edwin

你下载的是哪里的源码？要下载https://gitee.com/verimaker/bouffalo_sdk_vmg0/tree/vmg0/这个仓库的vmg0分支。我看你的目录不太对啊。clone这个仓库下来的话目录应该是bouffalo_sdk_vmg0，而不是bouffalo_sdk_vmg0-vmg0吧。
编译和烧写的方法参照帖子：https://verimake.com/d/407-bl6181
这个帖子中文件夹和你的有区别，因为你的描述不全面所以不知道你的问题在哪里。不过这里要注意如果你使用的是example中的样例，请一定要在编译时候加上CHIP和BOARD的设置，如图指令。

BooL

Edwin 我的板卡是BL618G0，官方最新的板子里面没有g0，然后我又翻到了很久之前的sdk，然后下载了这个，两个都试了

BooL

Edwin https://verimake.com/d/407-bl6181这个帖子链接中下载链接https://gitee.com/verimaker/bouffalo_sdk_vmg0下载后就是bouffalo_sdk_vmg0-vmg0

Edwin

BooL 博流的官方sdk中没有g0开发板。g0是verimake设计，sdk是在官方的sdk基础上做了修改的。

Edwin

这个仓库https://gitee.com/verimaker/bouffalo_sdk_vmg0/tree/vmg0/ 不要错了。不是去博流的官方git哦。
选这个分支git clone https://gitee.com/verimaker/bouffalo_sdk_vmg0.git

不要自己组装sdk环境。按这个教程走一遍试下https://verimake.com/d/407-bl6181，不然没办法对齐信息。

Edwin

BooL 你没有安装git吗？不要下载zip，要使用git clone命令 🤣
帖子上说了的啊。

BooL

Edwin 哦哦好，那我用Git

Edwin

BooL 还有下载时候按帖子介绍的，不要按错了boot键。是res旁边的boot

这次应该是按照官方方式吧，但是还是不行

BooL

Edwin
不应该是这个boot键吗？按res旁边的boot键设备管理器里面都不会出现端口

Edwin

下载后按下复位RES键。看下你的串口助手和设备管理器信息
我这里下载后复位，串口出来的信息：

BooL

Edwin
是没出现任何信息

Edwin

BooL 额。不是，这个是下载器的boot，你把下载器烧没了。所以没有cklink了。你下载错了

BooL

出现串口号

Edwin

BooL
刷回固件的方法，有两种，可以使用第二种图形化方法
https://verimake.com/d/303-bl618-g0cklink
烧写回固件，记得按你之前按的boot。
烧写样例程序的时候记得：按那三排按键里的boot和RES，仔细看下。

BooL

Edwin 那坏了，当时第一次给学弟烧的，可能给烧没了

BooL

Edwin 那我怎么办？怎么能再烧进去cklink

BooL

Edwin 感谢大佬，已经解决了，辛苦您了

Edwin

BooL 好，只要知道独立boot是烧写cklink调试器固件，三个一排按键里面boot是烧写自己设计程序到主控。就OK了。

Edwin

BooL 你烧写回固件，设备管理器里面应该有cklink，然后烧写样例的时候应该按三个按键一排的里面的boot键进入boot模式。不要随意乱按进入boot模式，烧写固件按原来你按的那个独立boot键进入boot模式。烧写固件，不要随便乱按，跟烧写几遍没有任何关系，烧写对了就一遍就行。
首先。不按任何按键，插上设备，查看设备管理器。查看串口号和usb设备信息

这样就是你下载器的串口号和设备，如果没有usb设备里面的cklink，那么你的固件可能没有烧写回去。接下来按步骤来做：
1、拔下设备。然后按住独立的boot按键，插usb。注意按住独立boot插设备。然后松开boot，烧写固件。
2、烧写完成后，拔下设备，不按任何按键，插上设备查看。应该就有了。如果没有查看usb设备是不是一个感叹号设备，这样就是有可能驱动没有安装。

然后：有cklink设备那么下载器就是恢复了。不按任何按键，插上设备。然后按住三个一排按键中的RES和BOOT，先松开RES，再松开BOOT，就可以下载样例程序了。
