单片机是可以正常识别到的,但是无法正常下载程序。在网上找了很多办法。如读写被锁了呀。用J_FLASH 也试的。但是无法擦除芯片。可以连接上。 最后解决办法:将SW 的速度降低一些。我的下载线接了比较的杜邦线(劣质杜邦线害死人呀!!!),原来的设置是5M,改成100Khz 就可以正常下载了。 在此记录一下踩过的坑!!!

问题3:安装J-Link驱动后,依然无法烧录程序,报错Flash Download failed “Cortex-M4”以及The connected J-Link is defective。。。 对应解决方案:前者通过在keil中配置Jlink即可,后者由于keil5.25及更高版本默认安装高版本的J-Link驱动,需要将keil5.25自带的J-Link.exe文件(默认C:Keil_v5\ARM\Segger)替换为自己安装...
