修改 u-boot

MQ-Quad 没有以太网接口执行 make menuconfig 在主页关闭网络支持：【】Networking support
MQ-Quad 使用 axp313 电源管理芯片修改drivers/power/axp305.c文件：

主线 Kernel 编译

拉取/下载压缩主线内核

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
# 速度较慢，直接去官网下载 mainline 内核：https://kernel.org

# 解压内核
tar -xvzf linux-6.0-rc3.tar.gz

修改设备树

/arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dts

# 因为 MQ-Quad 的 3.3v 是没接 pmic 来控制的，所以要添加固定 3.3v 的节点
# 在 reg_vcc5v 节点下面添加 reg_vcc3v3 节点 （否则无法初始化IO，导致串口无法初始化）
reg_vcc3v3: vcc3v3 {
	compatible = "regulator-fixed";
	regulator-name = "vcc-3v3";
	regulator-min-microvolt = <3300000>;
	regulator-max-microvolt = <3300000>;
	regulator-always-on;
};

# 修改 pio 节点中的 reg_aldo1 为 reg_vcc3v3
&pio {
	vcc-pc-supply = <&reg_vcc3v3>;
	vcc-pf-supply = <&reg_vcc3v3>;
	vcc-pg-supply = <&reg_vcc3v3>;
	vcc-ph-supply = <&reg_vcc3v3>;
	vcc-pi-supply = <&reg_vcc3v3>;
};

# 修改 mmc0 的 vmmc-supply 的 reg_dcdce 为 reg_vcc3v3（否则无法启动 sunxi-mmc 驱动）
&mmc0 {
	vmmc-supply = <&reg_vcc3v3>;
	cd-gpios = <&pio 5 6 GPIO_ACTIVE_LOW>;	/* PF6 */
	bus-width = <4>;
	status = "okay";
};

配置编译

# 使用默认配置
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig

# 编译内核镜像
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8 Image

# 编译设备树
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8 dtbs

# 编译模块（可选，后面做了文件系统后再使用）
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j8 modules
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=<any-path-you-like> modules modules_install
构建成功后，可以在提供的 INSTALL_MOD_PATH 目录中找到模块

# 安装头文件（可选，后面做了文件系统后再使用）
make ARCH=arm64 INSTALL_HDR_PATH=<any-path-you-like> headers_install
将 INSTALL_HDR_PATH 更改为希望安装到的路径，例如/usr或<some_prefix>/usr 方便后期交叉编译

制作引导脚本（当然也可以在uboot中设置变量并执行booti）

制作 boot.cmd 文件， USB 写入内核直接使用固定地址启动

vi boot.cmd
# 复制以下内容
setenv bootargs console=ttyS0,115200
booti 0x40200000 - 0x4fa00000

转换打包boot.scr文件：mkimage -C none -A arm64 -T script -d boot.cmd boot.scr
booti 讲解：
在u-boot中，bootm是一个可以执行位于memory中的应用程序的命令
booti是bootm命令的一个子集，可用于执行位于memory中的ARM64 kernel Image，其格式如下：
booti addr [initrd[:size]] [fdt]
其中：addr是kernel Image文件所在的memory地址；[initrd[:size]]是initrd在memory中的位置和size，可以不指定，使用“-”代替即可；fdt是flat device tree（就是传说中的dtb文件）在memory中的地址，在ARM64中，它是必选的

测试 USB 启动内核

sunxi-fel -v uboot u-boot-sunxi-with-spl.bin \
             write 0x40200000 Image \
             write 0x4fa00000 sun50i-a64-pine64-lts.dtb \
             write 0x4fc00000 boot.scr \
             write 0x4ff00000 rootfs.cpio.lzma.uboot

# 例如：
./sunxi-tools/sunxi-fel -v uboot u-boot/u-boot-sunxi-with-spl.bin \
write 0x40200000 linux-6.0-rc3/arch/arm64/boot/Image \
write 0x4fa00000 linux-6.0-rc3/arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dtb \ 
write 0x4fc00000 boot.scr

添加网络支持

因为6.0的内核太新了，很多驱动没支持，所以使用稳定版内核进行驱动的移植

下拉内核

H616主线内核维护者的内核：git clone -b h616-v13 https://github.com/apritzel/linux
使用主线需修改设备树，按照主线内核的修改配置方法

移植 RTL8723DS WiFi 驱动

git clone https://github.com/lwfinger/rtl8723ds 到 /drivers/net/wireless/realtek/rtl8723ds 目录中
修改 rtl8723ds 的 Kconfig 中 ---help--- 为 help

config RTL8723DS
	tristate "Realtek 8723D SDIO or SPI WiFi"
	help
	  Help message of RTL8723DS

修改 /drivers/net/wireless/realtek/ 目录中的Kconfig、Makefile：

# Kconfig 中添加新的驱动
source "drivers/net/wireless/realtek/rtl8723ds/Kconfig"
# Makefile 中添加新的驱动
obj-$(CONFIG_RTL8723DS)		+= rtl8723ds/

打开 WiFi(RTL8723DS) 支持
