CM4 kinetis K40 IAR连接问题

kevinht

新人求教，以前没用过freescale的片子
板子是KwikStik-K40，不知道有没有用过这个板子的前辈
用IAR下载程序的时候，始终连接不上
不知道我的IAR设置有没有问题
在general option里面选的是Device Freescale K40Xxxx
在Debugger里面选的是J-LINK/J-Trace
在J-LINK/J-Trace里面connection选的是USB，interface选过JTAG也选过SWD，但都下不了
 
选JTAG的时候弹出下面这个

debug log 是下面这样的

谢谢你的关注
支持的，这个板子上有JLINK的片子，通过USB和电脑连接，再通过JLINK方式下载
“An on-board SEGGER J-Link debug circuit provides a JTAG and SWD interface and a power supply input 
through a single USB micro-B connector.”
