JLink ARM的安装软件包 安装完成后才能通过J Link连接STM32，完成代码烧写或debug，以及如果遇到芯片被锁的情况，也可以通过Unlock来解锁

J-Link是SEGGER公司为支持仿真ARM内核芯片推出的JTAG仿真器。配合IAR EWAR，ADS，KEIL，WINARM，RealView等集成开发环境支持所有ARM7/ARM9/ARM11,Cortex M0/M1/M3/M4, Cortex A5/A8/A9等内核芯片的仿真，与IAR,Keil等编译环境无缝连接，操作方便、连接方便、简单易学，是学习开发ARM最好最实用的开发工具

很多版本Jlink驱动被检测出后不让使用，找了个正常的，不过最好还是4.6之前版本

STM32烧写软件，可脱离KEIL等编程软件烧写，需要烧写hex类的文件，安装软件后建立工程形成jflash文件，然后添加编好的hex类文件。配置好设置后，按F7烧写。

Jlink固件烧录软件，固件源文件。Windows11以下完全没问题。 用于修复Jlink固件损坏。

之前笔者的J-Link-V11变砖了，用J-link自带的J-Link-Configurator无法成功刷写固件（每次都是提示更新固件成功，但是拔掉USB线再插上之后又是提示J-Link运行在BootLoader模式），用这个软件才成功恢复固件。下载解压后双击Jlink.exe然后按照给出的提示运行即可。
