支持JLINK的文件安装了吗,几年前用N32时候看文件里面有452啊
<Device>
<ChipInfo Vendor="Nationstech" Name="N32G452VE"
Core="JLINK_CORE_CORTEX_M4" WorkRAMAddr="0x20000000"
WorkRAMSize="0x00024000"/>
<FlashBankInfo Name="Internal Flash" BaseAddr="0x08000000"
MaxSize="0x00080000"
Loader="Devices/Nationstech/N32G45x_NRP_512K.FLM"
LoaderType="FLASH_ALGO_TYPE_OPEN" AlwaysPresent="1"/>
</Device>
可以打开JLINK命令行试试能不能连连上,先输入h 然后Device> N32G452VE 能连上能显示出寄存器信息,J_LINK V9可能要4根线连接板子
