OK1043A-C開發板RM500Q-GL調試筆記 2021.7.9
設置串口工具，使用RS-232線纜將開發版與PC連接，使用USB轉COM線纜需安裝驅動，檢查任務管理器中COM口狀態，圖中所示使用COM3口通訊。
5G轉接卡安裝SIM卡並上電，通過USB與開發版連接，打開putty，按照如圖所示配置串行口為COM3，波特率為115200。
按回車進入命令行界面，用戶名和密碼均為root
移遠 RM500Q-GL 模塊測試：
控制台輸入lsusb檢查5G模塊是否連接成功
使用 ifconfig 命令可以看到移遠 RM500Q-GL 5G 模塊模塊產生的節點名稱為 eth0
以插入移動 SIM 卡測試 5G 上網為例，測試是否連接外網：

撥號完成之后需要運行 dhclient 命令
