```

**选择板卡**

```
$ ./build.sh lunch 
```

> 根据需要选择 k5 或 k5c

**编译完整镜像**

```
$ ./build.sh 
```

## 单独编译

单编 kernel

```
$ ./build.sh kernel
```

单编 rootfs

```
$ ./build.sh rootfs
```

## Kconfig配置

方式一：kconfig 修改及保存

```
$ ./build.sh config
$ cd kernel/linux-4.9/
$ make ARCH=arm64 menuconfig
$ cd -
$ ./build.sh saveconfig
```

方式二：命令集成

```
$ ./build.sh menuconfig
```

> 如果命令未支持，可自行添加添加补丁修改；

## 设备树路径

```
kickpi-k5c.dts/device/config/chips/a133/configs/c3/kickpi-k5c.dts
```

## 工具链

包路径

```
build/toolchain/gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu.tar.xz
```

编译后工具的路径

```
out/gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu
```

## 常见问题

### 提示缺少 event.c 文件问题

```
aarch64-linux-gnu-gcc: error: /home/A/sdk/a133/a133-linux-test1/kernel/linux-4.9/modules/gpu/img-rgx/linux/rogue_km/binary_sunxi_linux_release/target_aarch64/kbuild/services/server/env/linux/event.c: No such file or directory
```

需要进行清除操作

```
$ ./build.sh clean
```
