ST-link无法下载—— “ access port fault. check the access port selection and ensure it fits the debugging

ST-Link下载报错: “ access port fault. check the access port selection and ensure it fits the debugging context ”

无法下载代码,已经多次检查了下载口引脚(TMS和TCLK)和芯片引脚连接完好,芯片未烧坏,5v供电,稳压功能正常(3.3v),程序0 error , 0 warring;

debug中的SW Device 检测报错 “ access port fault. check the access port selection and ensure it fits the debugging context ”

已经多次使用复位按键方法下载,还是在SW Device 中报错 “ access port fault. check the access port selection and ensure it fits the debugging context ”
