20240919在友善之臂的NanoPC-T6开发板上适配宸芯的数传模块CX6602N
2024/9/19 16:54

缘起，大毛PK二毛战况激烈，穿越机大卖！我司拆同行的图传作品。
发现：
主控：飞凌OK3588-C核心板
图传模块：宸芯的数传模块CX6602N

于是费了老鼻子劲，联系上了宸芯。
技术支持需要派工单，经过多方协调，终于和上海的软件FAE对接上了。

宸芯的数传模块CX6602N支持三频段：800M、1.4GHZ、2.4GHZ。
支持USB接口（PIN69的DP和PIN70的DM）和HSIC接口（PIN2的HSIS_DATA，PIN4的HSIC_STROBE）

USB接口可以直接以虚拟以太网卡的形式接友善之臂的NanoPC-T6开发板。
HSIC接口接LAN9730转【百兆】以太网RJ45之后，接下位机！

2. 上位机配置
2.1 添加 rndis 和 gserial 主机驱动
进入 kernel 目录 make menuconfig，1．添加配置 CONFIG_USB_NET_RNDIS_HOST=m：

2．添加配置 CONFIG_USB_SERIAL=m：
2．添加配置 CONFIG_USB_SERIAL_GENERIC=y：
编译模块：make modules && make modules_install

2.2 加载驱动

1．加载 rndis 主机驱动：modprobe rndis_host
2．连接下位机，确认 rndis 驱动绑定 rndis 接口
3．查看下位机的 usb 设备 ID：
# lsusb
Bus 001 Device 006: ID 18d1:181f Google Inc.

root@rk3588-buildroot:/#

5．加载 gserial 主机驱动：modprobe usbserial vendor=0x18d1 product=0x181f
其中，0x18d1 是从机的 VID，0x181f 是从机的 PID

6．确认 gserial 驱动绑定 gserial 接口：
# lsusb -t

3.2 AT 及灌包测试

1．通过 USB 连接上位机后，使用 minicom 工具发送 AT 命令：
minicom -D /dev/ttyUSB0

2．利用 iperf 测试网络性能：
上位机配置 ipv4 地址：
ifconfig usb0 192.168.42.130
上位机作为 udp 服务端接收数据：
iperf -u -s -i 1
下位机作为 udp 客户端发送数据：
iperf -u -c 192.168.42.130 -i 1 -p 5001 -t 30 -b 200m
上位机作为 udp 服务端接收数据：
