一、下载Lichee官方指定Linux仓库及分支

> git clone --depth=1 -b f1c100s-480272lcd-test https://github.com/Icenowy/linux.git

二、配置Linux

> 1、下载 .config 文件，放入源码主目录进行替换 (若下载时文件名有变，请重命名回 .config );  
> [https://fdvad021asfd8q.oss-cn-hangzhou.aliyuncs.com/migrate/.config][https_fdvad021asfd8q.oss-cn-hangzhou.aliyuncs.com_migrate_.config]
> 
> 2、make ARCH=arm menuconfig

如图所示

> ### SPI-Flash的支持 ###
> 
> 进入 Device Drivers -> SPI support，将 Allwinner A10 SoCs SPI controller取消勾选，然后勾上下面的Allwinner A31 SPI Controller。这是为了修正配置文件中SPI驱动不正确的问题。
> 
> 勾上并进入 Device Drivers -> Memory Technology Device (MTD) support，选上下面两项：
> 
>  *  Command line partitioning table parsing \#为了解析内核参数传过来的分区信息，如果用设备树应该可以不选
>  *  Caching block device access to MTD devices  \#为了生成/dev/mtdblock\*设备，不选会在启动的时候卡在 watiting for device /dev/mtdblock\*

> 添加对JFFS2文件系统的支持

如下图

保存并退出

> 打开drivers/mtd/spi-nor/spi-nor.c，检查自己的flash型号的参数是否含有SECT\_4K，如果有则改为0

如下图

四、编译

执行编译命令

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j8

经过编译

在linux/arch/arm/boot/zImage的目录生成 kernel镜像

在linux//arch/arm/boot/dts/suniv-f1c100s-licheepi-nano.dtb生成设备树编译文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xhbjEyMDU3NjY2NA_size_16_color_FFFFFF_t_70 6][]

至此,Linux编译完成
