RTL8811CU｜RTL8821CU网卡移植到StarFive(Verison Five2)
星光板2(VisionFive 2)使用USB无线网卡，自行编译驱动。
情况说明：
1、京东购入两个USB无线网卡EDUP EP-AC1651）芯片 RTL8811CU 链接直达
2、手中两块板子 version five2， raspberry pi 2B
3、version five2 使用官方debian镜像、 Raspberry Pi 2 Model B Rev 1.1 使用kali Linux for raspberry 镜像
0、基本编译环境准备
# 安装基本工具和编译工具
sudo apt install -y build-essential gcc-riscv64-linux-gnu libncurses-dev
sudo apt install -y git flex bison bc vim-tiny wget
sudo apt install iw im-config usbutils pciutils iputils-ping
一、先从简单的来：为Raspberry Pi 2 Model B Rev 1.1安装驱动（超级简单）亲测可用

二、接下来是重头戏： 为 version five2 安装驱动：
下载赛昉官方提供了星光2系统的定制内核源码 时间超级长，repo很大
cd ~
// 1、准备系统内核源码
git clone git@github.com:starfive-tech/linux.git
cd linux
touch .scmversion
git checkout -b JH7110_VisionFive2_devel origin/JH7110_VisionFive2_devel
git pull
vi Makefile
// 编辑Makefile文件
VERSION = 5
PATCHLEVEL = 15
SUBLEVEL = 0
EXTRAVERSION = -starfive # 这里的版本号很重要， 需要和当前系统的内核版本号保持一致
NAME = Trick or Treat
// 编译
make starfive_visionfive2_defconfig
make -j3
// 系统内核准备完毕
cd ~
// 2、准备驱动文件源码
git clone git@github.com:brektrou/rtl8821CU.git
cd rtl8821CU
// 编辑Makefile文件
修改 CONFIG_PLATFORM_I386_PC = y
为 CONFIG_PLATFORM_I386_PC = n
增加
CONFIG_PLATFORM_RISCV = y
ifeq ($(CONFIG_PLATFORM_RISCV), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
ARCH ?= riscv
CROSS_COMPILE ?=
KVER ?= $(shell uname -r)
# 注意下面KSRC 修改为第一步系统内核源码的文件路径
KSRC ?= /root/linux
MODDESTDIR := /lib/modules/$(KVER)/kernel/drivers/net/wireless/
endif
//
// 开始编译 漫长等待
make
// 如果不出意外
root@risc- ~/rtl8821CU$ ls
8821cu.ko 8821cu.mod.c 8821cu.o LICENSE Module.symvers changelog.pdf core dkms-install.sh dkms.conf ifcfg-wlan0 modules.order platform runwpa
8821cu.mod 8821cu.mod.o Kconfig Makefile README.md clean debian dkms-remove.sh hal include os_dep rtl8821c.mk wlan0dhcp
// 其中8821cu.ko就是我们要的文件 6.2M 大小，熬了一整夜！！！！
// 安装
make install
root@risc- ~/rtl8821CU$ make install
mkdir -p /lib/modules/5.15.0-starfive/kernel/drivers/net/wireless/

如果
root@risc- ~/8821cu-20210916$ dmesg -T
[Sat Jul 8 10:44:20 2023] usb 1-1.3: USB disconnect, device number 3

说明系统内核的 EXTRAVERSION 有问题需要修改为
EXTRAVERSION = -starfive 回到重新编译内核，继续以上步骤。
*****最后在给网卡重命名的时候一定要确定mac地址正确。 可以通过dmesg -T 查看mac地址*****
