MQ-Quad 全志H616 主线内核编译调试记录(u-boot、kernel、buildroot) [复制链接]

# U-Boot 构建并从USB启动

### 安装 sunxi-fel 工具：
```
git clone https://github.com/linux-sunxi/sunxi-tools
cd sunxi-tools/
make
```

### Arm Trusted Firmware (arm64)
```
git clone https://github.com/ARM-software/arm-trusted-firmware.git
cd arm-trusted-firmware
make CROSS_COMPILE=aarch64-linux-gnu- PLAT=<platform> DEBUG=1 bl31

# platform = sun50i-h616
```

### 下拉最新的 u-boot
```
git clone git://git.denx.de/u-boot.git
cd u-boot
```

### 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：
```c
# 注释掉 DCDC4 的设置 axp313并没有这路输出
int axp_set_dcdc4(unsigned int mvolt)
{
    int ret;
    u8 cfg;

#if 0
    if (mvolt >= 1600)
        cfg = AXP305_DCDC4_1600MV_OFFSET +
            axp305_mvolt_to_cfg(mvolt, 1600, 3300, 100);
    else
        cfg = axp305_mvolt_to_cfg(mvolt, 600, 1500, 20);

if (mvolt == 0)
        return pmic_bus_clrbits(AXP305_OUTPUT_CTRL1,
                    AXP305_OUTPUT_CTRL1_DCDCD_EN);

ret = pmic_bus_write(AXP305_DCDCD_VOLTAGE, cfg);
    if (ret)
        return ret;

return pmic_bus_setbits(AXP305_OUTPUT_CTRL1,
                AXP305_OUTPUT_CTRL1_DCDCD_EN);
    #endif
    return 0;
}

# 添加 DCDC3 的电压设置

#define AXP305_DCDC3_1200MV_OFFSET 71
int axp_set_dcdc3(unsigned int mvolt)
{
    int ret;
    u8 cfg;

if (mvolt >= 1220)
    {
        cfg = AXP305_DCDC3_1200MV_OFFSET +
            axp305_mvolt_to_cfg(mvolt, 1220, 1840, 20);
    }
    else
        cfg = axp305_mvolt_to_cfg(mvolt, 500, 1200, 10);

if (mvolt == 0)
        return pmic_bus_clrbits(AXP305_OUTPUT_CTRL1,
                    AXP305_OUTPUT_CTRL1_DCDCD_EN);

ret = pmic_bus_write(AXP305_DCDCD_VOLTAGE, cfg);
    if (ret)
        return ret;
 
    return pmic_bus_setbits(AXP305_OUTPUT_CTRL1,
                0x1f);
}

# 修改芯片版本的检测 以及 设置 DCDC3 的电压为1.5v
int axp_init(void)
{
    u8 axp_chip_id;
    int ret;

ret = pmic_bus_init();
    if (ret)
        return ret;

ret = pmic_bus_read(AXP305_CHIP_VERSION, &axp_chip_id);
    if (ret)
        return ret;

// if ((axp_chip_id & AXP305_CHIP_VERSION_MASK) != 0x40)
    //     return -ENODEV;

if ((axp_chip_id & AXP305_CHIP_VERSION_MASK) != 0x4b)
        return -ENODEV;

printf("pmic id is 0x%x\n",axp_chip_id);

axp_set_dcdc3(1500);

return ret;
}
```

### 编译 u-boot
```
make CROSS_COMPILE=aarch64-linux-gnu- BL31=../arm-trusted-firmware/build/sun50i_h616/debug/bl31.bin orangepi_zero2_defconfig
make CROSS_COMPILE=aarch64-linux-gnu- BL31=../arm-trusted-firmware/build/sun50i_h616/debug/bl31.bin
```

### 测试 u-boot
- 通过 USB 启动 u-boot
```shell
../sunxi-tools/sunxi-fel uboot u-boot-sunxi-with-spl.bin
```

### UART0 中输出 LOG

# 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 = <®_vcc3v3>;
    vcc-pf-supply = <®_vcc3v3>;
    vcc-pg-supply = <®_vcc3v3>;
    vcc-ph-supply = <®_vcc3v3>;
    vcc-pi-supply = <®_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 = <®_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

```

# 从 TF 卡启动 SPL、U-Boot、Kernel

### 制作启动盘
```
# 进入磁盘管理
fdisk /dev/sdd

# 多执行几次删除所有分区
d

# 新建分区 （扇区为单位，前面空开20MB用于存放uboot，制作128MB的分区）
n
p
40960

w

# 进行 FAT 格式化
sudo mkfs.fat /dev/sdd1

# 写入 uboot 到 8KB 的位置
sudo dd if=./u-boot/u-boot-sunxi-with-spl.bin of=/dev/sdd bs=8K seek=1

# 挂载 FAT 文件系统
sudo mount /dev/sdd1 /mnt/boot/

# 复制内核以及设备树到FAT分区
sudo cp linux-6.0-rc3/arch/arm64/boot/Image /mnt/boot/
sudo cp linux-6.0-rc3/arch/arm64/boot/dts/allwinner/sun50i-h616-orangepi-zero2.dtb /mnt/boot/

# 卸载 FAT 文件系统
sudo umount /mnt/boot
```
### 测试 TF 卡启动内核
```
# 手动装载内核以及设备树并启动
fatload mmc 0:1 0x40200000 Image
fatload mmc 0:1 0x4fa00000 sun50i-h616-orangepi-zero2.dtb
setenv bootargs 'console=ttyS0,115200 earlycon'
booti 0x40200000 - 0x4fa00000

# 使用如下设置变量并保存到FAT分区
setenv bootargs 'console=ttyS0,115200'
setenv bootcmd 'fatload mmc 0:1 0x40200000 Image;fatload mmc 0:1 0x4fa00000 sun50i-h616-orangepi-zero2.dtb;booti 0x40200000 - 0x4fa00000'
saveenv

# 使用 bootcmd 启动
boot
```

# Buildroot 构建
buildroot-2022.02.5
### 配置编译
```
make menuconfig

# 配置 Target options

    -> [*] ubi image containing an ubifs root filesystem                 //如果使用 NAND 的话就用 ubifs

# 编译
make -j8
```

### 补充
- External toolchain kernel headers series 的设置：
cat /usr/aarch64-linux-gnu/include/linux/version.h
```
#define LINUX_VERSION_CODE 266002
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
# 266002 转十六进制为 40A03 则版本号为 4.10.3
```

### 制作根文件系统到 TF 卡

# 格式化文件系统为 ext4
sudo mkfs.ext4 /dev/sdc2

# 装载并复制文件系统

sudo cp ./output/images/rootfs.tar /mnt/rootfs/
sudo tar -vxf /mnt/rootfs/rootfs.tar -C /mnt/rootfs
sudo rm /mnt/rootfs/rootfs.tar
sudo umount /mnt/rootfs
```

### 测试文件系统
```
# 在进入 uboot 后检查文件是否存在
ext4ls mmc 0:2

# 设置启动命令
setenv bootcmd 'fatload mmc 0:1 0x40200000 Image;fatload mmc 0:1 0x4fa00000 sun50i-h616-orangepi-zero2.dtb;booti 0x40200000 - 0x4fa00000'

# 设置 bootargs 变量
setenv bootargs 'console=ttyS0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait rwinit=/sbin/init debug panic=30'

# 启动内核以及根文件系统
boot
```
# 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
```
# make menuconfig

> Device Drivers 
>     > Network device support 
>         > Wireless LAN
>             [*] Realtek devices
>                 <M> Realtek 8723D SDIO or SPI WiFi
            
# 编译内核模块(在此我已经将 ARCH 以及 CROSS_COMPILE 固定到Makefile中，所以不需要带参)
make modules -j8
```

### Kernel 设备树配置
```
# 在 reg_vcc3v3 后面添加 WiFi 的电源配置

reg_vcc33_wifi: vcc33-wifi {
    /* Always on 3.3V regulator for WiFi and BT */
    compatible = "regulator-fixed";
    regulator-name = "vcc33-wifi";
    regulator-min-microvolt = <3300000>;
    regulator-max-microvolt = <3300000>;
    regulator-always-on;
    vin-supply = <®_vcc5v>;
};

reg_vcc_wifi_io: vcc-wifi-io {
    /* Always on 1.8V/300mA regulator for WiFi and BT IO */
    compatible = "regulator-fixed";
    regulator-name = "vcc-wifi-io";
    regulator-min-microvolt = <1800000>;
    regulator-max-microvolt = <1800000>;
    regulator-always-on;
    vin-supply = <®_vcc33_wifi>;
};

wifi_pwrseq: wifi-pwrseq {
    compatible = "mmc-pwrseq-simple";
    clocks = <&rtc 1>;
    clock-names = "osc32k-out";
    reset-gpios = <&pio 6 18 GPIO_ACTIVE_LOW>; /* PG18 */
    post-power-on-delay-ms = <200>;
};

# 添加 WiFi 的 mmc1 配置
&mmc1 {
    vmmc-supply = <®_vcc33_wifi>;
    vqmmc-supply = <®_vcc_wifi_io>;
    mmc-pwrseq = <&wifi_pwrseq>;
    bus-width = <4>;
    non-removable;
    mmc-ddr-1_8v;
    status = "okay";
};

# 编译设备树
make dtbs
```
- 完成后需要重新拷贝新的设备树到 FAT 分区

# Buildrootfs 配置
`make menuconfig`
```shell

```
`make -j8`

### 复制新的文件系统并安装模块
```
# 在buildroot中执行 替换根文件系统
sudo mount /dev/sdd2 /mnt/rootfs
sudo rm -rf /mnt/rootfs/*
sudo cp output/images/rootfs.tar /mnt/rootfs/
sudo tar -xvf /mnt/rootfs/rootfs.tar -C /mnt/rootfs/

# 在内核中执行 安装模块到第二分区的rootfs中（因为内核没经过裁剪会有大量的模块安装到第二分区，可能需要调整下第二分区的大小）
make INSTALL_MOD_PATH=/mnt/rootfs/ modules modules_install

# 卸载rootfs

# 制作 TF 启动镜像

### 准备工作
```
# 创建 images 目录
mkdir images
cd images

# 收集需要用到的文件到 file 目录
mkdir file 
cp ../u-boot/u-boot-sunxi-with-spl.bin ./file
cp ../linux-5.19.0/arch/arm64/boot/Image ./file
cp ../linux-5.19.0/arch/arm64/boot/dts/allwinner/mq-quad.dtb ./file// 这里我已经单独做了个设备树文件
cp ../buildroot-2022.02.5/output/images/rootfs.tar ./file

# 制作空的 img 文件
sudo dd if=/dev/zero of=./sdcard.img bs=1M count=512
```

### 分区
```
sudo fdisk ./sdcard.img
n
p
1
40960
+131072 // 64MB

n
p
2
172033
1048575 // 默认

w
```

### 关联 img 文件到 loop
```
sudo losetup -f ./sdcard.img

#查看关联到哪个位置
sudo losetup -l
/dev/loop11   0  0   00 /home/evler/Allwinner/MangoPi/Quad/mainline/images/sdcard.img
```

### 写入 uboot 到 img 文件中偏移 8KB 的位置
```
sudo dd if=./file/u-boot-sunxi-with-spl.bin of=/dev/loop11 bs=8K seek=1
```

### 关联分区设备
```
# 参考分区：
设备    启动 起点  末尾 扇区大小 Id 类型
./sdcard.img1   40960172032 131073 64M 83 Linux
./sdcard.img2  172033 1048575 876543428M 83 Linux

# -o （起始扇区 * 扇区大小）--sizelimit （扇区数量 * 扇区大小） 字节
sudo losetup -f -o 20971520 --sizelimit 67109376 sdcard.img 
sudo losetup -f -o 88080896 --sizelimit 448790016 sdcard.img

#查看关联到哪个位置
sudo losetup -l
/dev/loop3067109376 20971520   00 /home/evler/Allwinner/MangoPi/Quad/mainline/images/sdcard.img
/dev/loop26 448790016 88080896   00 /home/evler/Allwinner/MangoPi/Quad/mainline/images/sdcard.img
```

### 格式化并挂载分区
```
sudo mkfs.fat /dev/loop30
sudo mkfs.ext4 /dev/loop26

sudo mount /dev/loop30 /mnt/boot/
sudo mount /dev/loop26 /mnt/rootfs/
```

### 制作uboot引导脚本
```
# 创建 boot.cmd 文件
vi boot.cmd

# 复制以下内容
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait rw
setenv bootcmd fatload mmc 0:1 0x4fc00000 boot.scr; fatload mmc 0:1 0x40200000 Image; fatload mmc 0:1 0x4fa00000 mq-quad.dtb; booti 0x40200000 - 0x4fa00000

# 生成 boot.scr 文件
mkimage -C none -A arm64 -T script -d boot.cmd boot.scr
```

### 制作 boot 分区
```
sudo cp ./file/Image /mnt/boot/
sudo cp ./file/mq-quad.dtb /mnt/boot/
sudo cp ./file/boot.scr /mnt/boot/
```

### 制作 rootfs 
```
# 解压 buildroot 制作出来的根文件系统压缩文件到 rootfs 分区
sudo tar -vxf ./file/rootfs.tar -C /mnt/rootfs/

# 安装内核模块到 rootfs 分区
cd ../linux-5.19.0/
sudo make INSTALL_MOD_PATH=/mnt/rootfs/ modules_install
```

### 卸载文件系统
```
sync
sudo umount /mnt/rootfs
sudo umount /mnt/boot
```

### 取消环路的关联
```
sudo losetup -d /dev/loop30
sudo losetup -d /dev/loop26
sudo losetup -d /dev/loop11
```

### 写入到 TF 卡进行测试
```
sudo dd if=./sdcard.img of=/dev/sdd
```
