【已解决】j-link 接rg100a-aa jtag口，识别不出cpu

ston***

感谢帮助我的朋友！
确认是jlink版本问题，或者说需要特别设置（不要问我，我也不会）
现在使用版本信息如下
------------------------
Firmware: J-Link ARM V8 compiled Dec  1 2009 11:42:48


这两天想把j-link用起来，却遇到不少问题

先是j-link没有反应，后来刷了firmware可以好了
安装了jlink 425a驱动，usblib

高兴的使用H大的Brjtag 1.9o 测试
可以识别 j-link，但不能识别6358的cpu

情况如下

确认是jlink版本问题，或者需要特别设置（不要问我，我也不会）。

现在使用版本信息如下
------------------------
Firmware: J-Link ARM V8 compiled Dec  1 2009 11:42:48

接线顺序如下
-----------------
rg100a -- jlink
vcc-1
3-5
5-13
7-7
9-9
gnd-gnd

成功备份cfe和wholeflash
