jink SWD下载 设置了芯片 debug设置jink下载 setting里设置sw 100k    flashdownload里设置stm32f10x 512k
问题出在哪呢？

瞎点的，能下载进去了，在jlink setting 里sw的速度点了下auto clk  它自动设置的50khz
可以下载了   串口有显示 不过怪怪的

正点原子

查看下是不是flash被锁了

bin133

识别出芯片了吗

用jlink查看option byte里面相关地址的值是否上锁， 根据型号查阅手册。另外你设定的这个烧录速度也太低了吧，芯片支不支持这么低的波特率，我一般都用1Mhz。从你的烧录信息来看， xspr寄存器值错误，这个寄存器和芯片的保持状态有关，肯定某个设定搞错了。要么是启动方式，要么是上锁之类的问题，自己摸索下吧。
