我还以为这2个J-LINK内部的固件不一样，于是连接了目标板，得到的信息一致，也就是J-LINK里面的固件是一样的，有截图。
2个J-LINK都能检测到CPU为ARM926-EJS内核
出错的J-LINK调试时出现错误对话框，大概内容为：
this target device does not support all the defined breakpoints！
please reduce the number of breakpoints and start again
..........
this target device does not support all the defined breakpoints！
please reduce the number of breakpoints and start again
修改AXD的options-->config processor.
去掉所有的选项（小方框内为空）。
重起AXD试试。
This target device does not support all the defined breakpoints
Too many breakpoints have been defined. Reduce the number of breakpoints. The following breakpoint combinations are supported:
When executing from volatile (RAM) memory:
unlimited address breakpoints and one data access breakpoint
two data access breakpoints
When executing from non-volatile memory, for example Flash:
two address breakpoints
two data access breakpoints
one address breakpoint and one data access breakpoint
