# Debian 12 WSL2下为H88K编译内核为例
sudo apt install dpkg-dev build-essential bc flex bison python-is-python3 libncurses-dev libelf-dev libssl-dev gcc-aarch64-linux-gnu


# WSL1编译的话需要如下剔除Windows的PATH内容
sudo vi /etc/wsl.conf
[interop]
appendWindowsPath = false


# WSL设置代理来加速源码下载，没有代理可跳过或根据需求设置。如下是WSL1设置网络代理的例子
export all_proxy="http://172.23.240.1:7890"

# 获取源码
git clone --depth=1 -b rk-5.10-rkr6 https://github.com/armbian/linux-rockchip
cd linux-rockchip/

wget -O .config https://github.com/armbian/build/raw/main/config/kernel/linux-rk35xx-legacy.config
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- menuconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc)

# 开始安装内核到指定位置，最好切换到root用户再安装模块，否则可能模块权限将混乱
KERNEL_PATH=/home/leux/kernel
sudo mkdir -p ${KERNEL_PATH}/boot/			# INSTALL_PATH不存在会报错
sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- install INSTALL_PATH=${KERNEL_PATH}/boot
sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- modules_install INSTALL_MOD_PATH=${KERNEL_PATH}
sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- headers_install INSTALL_HDR_PATH=${KERNEL_PATH}/usr
sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- dtbs_install INSTALL_DTBS_PATH=${KERNEL_PATH}/boot/dtb-5.10.160

# 也可以直接编译打包成DEB，生成的DEB包文件在内核源码的上一级目录下
# sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg -j$(nproc)


# 如果内核开启了 CONFIG_DEBUG_INFO 选项，那么编译的内核模块会把调试信息也带进去，导致模块的大小剧增，添加 INSTALL_MOD_STRIP=1 可去除
sudo make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_STRIP=1 modules_install INSTALL_MOD_PATH=${KERNEL_PATH}

# 可以看到经过STRIP了所以很小，而没有STRIP则空间占用巨大

编译错误解决

  1. 可能是GCC版本较新的原因导致下面的一系列问题，注释掉 linux-rockchip/scripts/gcc-wrapper.py 第105行来禁用 interpret_warning 即可解决

        proc = subprocess.Popen(args, stderr=subprocess.PIPE, env=env)
        for line in proc.stderr:
            print (line.decode("utf-8"), end="")
-           interpret_warning(line.decode("utf-8"))
+           #interpret_warning(line.decode("utf-8"))
        if do_exit:
            sys.exit(1)

  1. 由于当前内核版本不支持MT7916，所以可以通过backport来支持它

# 打补丁来支持MT7916网卡
wget https://github.com/amazingfate/armbian-h68k-images/raw/master/backport-v6.1.39.patch
cd linux-rockchip/ && patch -p1 < backport-v6.1.39.patch

# 先关闭BSP内核自带的驱动，因为自带驱动和Backport驱动只能二选一

# 在如下位置开启MT7915E，它依赖CFG80211和MAC80211
