使用RK1808M0 AI计算卡

测试环境：

  • RK1808M0 AI计算卡
  • LKD3588

其他Neardi产品也可以参考本指南。

Toybrick TB-RK1808M0 AI计算卡（简称计算卡）搭载瑞芯微RK1808神经网络处理器，配置1GB内存，采用标准Mini-PCIe接口，DIP开关可切换USB3.0和mini-PCIe数据通信，计算卡遵循Mini-PCIe规范，可通过DIP开关在两种模式间切换：

对于LKD3588，使用USB通信，DIP开关应向下切换。

主动模式开发和环境介绍​

  • 确认USB硬件连接正常。

将RK1808 AI计算棒插入PC的USB端口，使用lsusb命令检查，如下所示（其中2207:0018代表RK1808 AI计算棒）：

  • 当RK1808计算棒插入主机时，它将被虚拟化为网卡设备。
neardi@LPA3588:~$ ifconfig -a

enx10dcb69ff286是USB网卡（RK1808 AI计算棒的虚拟网卡）。

  • 在主机上配置虚拟网卡，设置IP为192.168.180.1，确保主机与RK1808之间的网络连接正常。

配置虚拟网卡固定IP为192.168.180.1：

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

测试网络连通性：

neardi@LPA3588:~$ ping 192.168.180.8
