大家好,最近被一个问题困扰着,手头有个ST- Link V2,U盘大小的那种,见下面图片这种,
主控是STM32F103C8,插电脑提示无法识别的硬件,就想自己通过Jlink的SWD口重刷ST-LINK V2固件,ST-LINK v2 和 Jlink 口的联线如下:
SWCLK---JCLK(JLINK的9脚)
SWDIO---JTMS(JLINK的7脚)
RST---JNRST(Jlink的3脚和15脚均试了)
ST-LINK V2的VCC和GND ,Jlink均与电脑USB口连接,可以确定是同一个电源;
用SEGGER 安装目录里的 J-Flash ARM,设置好后,点击连接,提示如下:

//问题是,点击Programe & Vreify后,提示如下。泪奔了。。。哪位大神帮忙给解决一下,感谢了!
