【求助】j-link 接rg100a-aa jtag口，识别不出cpu
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
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

我接线有问题吗？
怎么样可以让我用j-link v8 刷新 6358的flash
接线都确定正确不？ 本帖最后由 stonefive 于 2011-3-4 10:21 编辑
是这样的，jlink 送了一个20pin的延长线，刚好可以查到猫上，
猫-jlink对应关系
3-3
4-4
5-5
6-6
7-7
8-8
9-9
10-10
另外jlink pin1 接了猫的vcc
回复 antitel 的帖子

接线顺序如下
rg100a -- jlink

感谢帮助我的朋友！特别感谢hotqj版大！
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 Dec1 2009 11:42:48
接线顺序如下
-----------------
rg100a -- jlink
