I'm using micro-usb for power supply and openSDA to debug the KW36 board

IDE mcuXpresso can probe the cmsis-dap, but show err msg as below

debug固件的问题,简单说,有不同的调试固件包括cmsis-dap,jlink,等等dap固件不行,于是就换成jlink固件

把debug固件改成jlink。长按复位按钮,然后插usb,磁盘应该出现一个类似daplinkboot的盘符,然后把附件解压,把bin文件拖进去,然后再试试

按上面说的更新完固件就行了,不需要设置什么,然后mcuxpresso按住shift+debug来重新调试

嗯 force probe 确实可以了,但是之前可以识别到 CMSIS-DAP,

更新固件,shift + probe 之后,方式 变成了 jlink,这个对吗。效果确实是可以 debug 了,停在了 main
