手順/Steps

1.　Burn TinkerOS_Debian V1.8 to microSD, and boot
2.　パッケージ更新

```bash:Update_packages(Optional??)
sudo apt update && sudo apt upgrade -y && sudo reboot
```

3.　必要なパッケージインストール

```bash:Install_packages_for_kernel_build
sudo apt update && sudo apt install -y git-core build-essential bc libssl-dev device-tree-compiler
```

4.　ソース取得

```bash:Kernel_source_code
git clone --depth 1 -b linux4.4-rk3288 https://github.com/TinkerBoard/debian_kernel.git
# Move to source code directory
cd debian_kernel
```

5.　Patch (GCC6: avoiding warning of '-Wmisleading-indentation')

```bash:Copy_And_Paste

```

5.　Edit Makefile for EXTRAVERSION (Optional)

```Makefile:Makefile(Example)
VERSION = 4
PATCHLEVEL = 4
SUBLEVEL = 16
EXTRAVERSION = mt08      # <--- example
NAME = Blurry Fish Butt

...
...
...
```

6.　ビルド

```bash:Build
# .config
make ARCH=arm miniarm-rk3288_defconfig

# zImage
time make ARCH=arm -j6 zImage 2>&1 | tee 1.log

#real 25m12.322s

time make ARCH=arm dtbs 2>&1 | tee 3.log

#real 0m8.204s
#user 0m3.110s
#sys 0m1.100s
```
6.　インストール

```bash:Install
# Modules
sudo make ARCH=arm modules_install

# Backup: old kernel & dtb
sudo mv -v /boot/zImage{,.bak}
sudo mv -v /boot/rk3288-miniarm.dtb{,.bak}

# Copy: new kernel & dtb
sudo cp -v arch/arm/boot/{zImage,dts/rk3288-miniarm.dtb} /boot

```

7.　sudo reboot
8.　:-)
