RK1808M0 AI计算卡使用

测试环境：

RK1808M0 AI计算卡
LKD3588

其他Neardi产品也可参考。

Toybrick TB-RK1808M0 AI计算卡（以下简称计算卡）搭载瑞芯微RK1808神经网络处理器，配置1GB 运行内存，采用标准的Mini-PCIe接口，通过拨码开关切换USB3.0与mini-PCIe数据通信，计算卡遵循Mini-PCIe规格，通过拨码开关切换两种模式：

RK1808计算棒插入上位机后，会被虚拟成网卡设备

neardi@LPA3588:~$ ifconfig -a

enx10dcb69ff286为USB网卡（RK1808人工智能计算棒虚拟网卡）。

上位机进行虚拟网卡配置，配置IP为192.168.180.1，保证上位机和RK1808中间的网络连接正常

虚拟网卡配置固定IP为192.168.180.1：

neardi@LPA3588:~$ sudo ifconfig enx10dcb69ff286 192.168.180.1
neardi@LPA3588:~$ ifconfig -a
