RK3288+RTL8201F-VB-CG网卡，在android5.1的3.10kernel上怎么配置？

Posted 2023-05-18

有没有人知道，还有哪里要改的？

由于在 RK 系列的 SoC 中内置了以太网 MAC 控制器，所以只需要搭配一颗以太网 PHY 芯片， 即可实现以太网卡功能。 按照规范，即使是不同厂家的 PHY，仍然有一部分寄存器的定义是通用的， 只要配置了这些通用的寄存器，基本上 PHY 就可以正常工作。 因此，在 Linux 驱动中有通用的 PHY 驱动，目前的芯片所配套的 SDK 中使用的都是通用驱动，当然 SoC 中的 MAC 驱动是需要实现的。 10/100M 以太网 PHY 与 MAC 之间的接口主要有 MII 和 RMII。 10/100/1000M 以太网 PHY 与 MAC 之间的接口主要有 RGMII。
网卡使用的是RTL8211,和参考设计一致，因此只要配置一下DTS就可以了。 参考技术A RK3288 android 5.1官方SDK（rk3288_android5.1_v1.00_20150515，已更新到20180412），在Rockchip官方提供的RK_EVB_RK3288核心板上验证OK。
根据Rockchip官方提供的补丁和配置方法，WiFi和以太网可以共存，而且WiFi配置连接因特网，以太网连接内部局域网，互不干扰。以下是具体的修改方法和补丁：

1）实现以太网wifi共存，补丁如下：

rk3288 usb无线网卡支持 8188eu

第一部分是kernel

内核配置参考rk文档，把device driver 下wireless相关的先勾选上。

编译到buildin有问题，识别不到，所以打算编译成ko

cd  kernel/drivers/net/wireless/rockchip_wlan/rtl8188eu

make -C /home/lzm/workspace/rk3288/zy_n10/kernel/  M=`pwd` modules

得到8188eu.ko

lsusb，看vid pid，是存在的

看初始化函数，发现被注释，修改打开

第二部分，android打开Settings配置

cd hardware/libhardware_legacy

mm

android源码目录下的build/envsetup.sh文件，描述编译的命令

• m: Makes from the top of the tree.
• mm: Builds all of the modules in the current directory.
• mmm: Builds all of the modules in the supplied directories.

要想使用这些命令，首先需要在android源码根目录执行. build/envsetup.sh 脚本设置环境

m：编译所有的模块
mm：编译当前目录下的模块，当前目录下要有Android.mk文件
mmm：编译指定路径下的模块，指定路径下要有Android.mk文件

下面举个例子说明，假设我要编译android下的\\hardware\\libhardware_legacy\\power模块，当前目录为源码根目录，方法如下：

1、. build/envsetup.sh
2、mmm hardware/libhardware_legacy/power/

或者 ：

1、. build/envsetup.sh
2、cd hardware/libhardware_legacy/power/
3、mm

adb shell am start com.android.settings/com.android.settings.Settings
