STM32在连接CPU时提示“connecting to CPU via connect under reset failed”通常是由于复位管脚配置不正确或硬件连接问题导致的。 针对这个问题,可以尝试以下几个步骤来解决: 检查硬件连接: 确保STM32的电源、地线连接正确,并且电压稳定。 检查复位电路是否工作正常,没有意外复位。 确保仿真器(如J-Link、ST-LINK)的...
问题意思：stm32在重置下通过连接连接到CPU失败。是否中止调试会话。问题原因：硬件使用的是J－LINK的SWD接口的接法，软件使用JTAG接口，因此在下载时会报告错误。解决办法：把JTAG接口设置重新配置一下就可以了。

***JLink Error: STM32: Connecting to CPU via connect under reset failed. Error: Flash Download failed - Target DLL has been cancelled 0 。先断电 按住复位 上电 1、按着板子上面的复位键不放,若没有按键,就用夹子短路复位电容,这样单片机将停止程序的运行;我的是工程板,RST端口接地就行了。
