JLink使用的芯片：STM32F205RC 为了防止公开链接被和谐，文章所需资源，请关注博主公众号，发送关键字 "jlink固件" 进行获取。1.问题描述在使用JLink v9的时候，不知道怎么回事，突然JLink v9的灯不亮了，将坏了的JLink插上电脑之后，设备管理器中也没有任何反应，连未知设备都没有。最开始以为是JLink被烧了，但细想这个仿真器也没有这么较弱啊，可能是JLink固件出了问题。于是上网查找资料，大致确认是固件出问题了，抱着试试的态度折腾一下吧，折腾不好就算了，万一折腾好了呢。2.准备过程<p style="box-sizing: border-box;

display: inline !important; float: none;">将坏的JLink v9板子上的程序下载接口焊接上，焊接上之后，要清楚这些接口的引脚定义，我这里坏的JLink v9板子的程序下载接口的引脚定义如下：<img src="/uploads/AilsonJack/2022.01.24/203528325895798.png" onclick="preview_image('/uploads/AilsonJack/2022.01.24/203528325895798.png')"/><p style="box-sizing: border-box;

text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; text-indent: 2em;">一个小插曲：我买的这个仿真器上面并没有丝印标出各个引脚的定义，问当时购买的商家，也不给我说引脚信息，没办法只好对照着STM32F205RC的引脚手册，使用万用表一个一个的找出各个引脚的定义，最终还真搞出来了。<p style="box-sizing: border-box; line-height: inherit; margin: 0.8em 0px; white-space: pre-wrap; position: relative; color: rgb(51, 51, 51); font-family: "Open Sans", "Clear Sans", "Helvetica Neue", Helvetica, Arial, "Segoe UI Emoji", sans-serif;

text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; text-indent: 2em;">使用一个好的JLink来对坏的JLink烧写丢失的固件。需要将坏的JLink上面刚才焊接的5个接口全部连接到好的JLink对应的引脚上：<img src="/uploads/AilsonJack/2022.01.24/203527017935701.png" onclick="preview_image('/uploads/AilsonJack/2022.01.24/203527017935701.png')"/><p style="box-sizing: border-box;

display: inline !important; float: none;">注意：我这里使用好的JLink的1脚给坏的JLink的STM32F205RC芯片供电，请确保好的JLink的1脚输出3.3V，坏的JLink不需要通过USB接口供电了。<p style="box-sizing: border-box; line-height: inherit; margin: 0.8em 0px;

display: inline !important; float: none;">将好的JLink连接上电脑，打开J-Flash，然后点击"Other..."，用J-Flash打开我提供的"jlink.jflash"文件，打开过程如下： <img src="/uploads/AilsonJack/2022.01.24/203528757297826.png" onclick="preview_image('/uploads/AilsonJack/2022.01.24/203528757297826.png')"/><p style="box-sizing: border-box;
