全志h3linux移植教程,Openwrt1806在全志H3上移植（银杏icore5）

目录下的linux内核源码压缩包解压到上述路径，并且将<.>目录内的补丁按照补丁的编号依次打上，如果出错则退出。准备好源码树后，就可以针对icore5，在dts目录下添加自己板子的设备树。直接添加的代码，在运行 make target/linux/clean时会被删除，只建议在测试时使用，测试通过后一定要制作补丁，否则代码丢了就得不偿失。

b. 打补丁添加

由上述步骤可知，编译时，会自动打补丁，也就是我们可以将补丁放到指定目录中，让系统自动打，这样也不会污染源码，更方便后续维护。制作补丁的方法，简单点就是准备好源码树后，进入源码目录，执行quilt new num-new.patch; 然后通过quilt edit 修改代码或者添加代码，最后执行quilt refresh生成补丁，将补丁拷贝至<.>目录内即可。

重新make menuconfig 选择icore5板子，编译；失败，看提示，应该时uboot缺失，因为更改了目标，uboot中还没有添加相应的规则。类似的，uboot 在<.>目录，发现该目录下也有个patch目录，是的，这个目录跟linux源码patch目录的作用时一样的。首先修改Makefile，添加icore5的配置

define U-Boot/icore5

BUILD_SUBTARGET:=cortexa7

NAME:=Icore5

BUILD_DEVICES:=sun8i-h3-icore5

endef

并在下边的UBOOT_TARGETS中添加icore5， 注意定义的名字应该与 **_defconfig 一致，如上述定义，我们应该在uboot源码树中添加icore5_defconfig; 这样在编译uboot时就会自动执行 make icore5_defconfig.

同样的，我们建议在uboot下打补丁修改代码。

最终验证

在目录添加配置 ，当前只有rgmii phy这一路通了，就先配一路， 内容如下：

config interface 'loopback'

option ifname 'lo'

option proto 'static'

option ipaddr '127.0.0.1'

option netmask '255.0.0.0'

config globals 'globals'

option ula_prefix 'fd71:468e:86c5::/48'

config interface 'lan'

option type 'bridge'

option ifname 'eth0'

option proto 'static'

option netmask '255.255.255.0'

option ip6assign '60'

option ipaddr '192.168.10.2'

config device 'lan_eth0_dev'

option name 'eth0'

option macaddr '0c:ef:af:c3:14:9e'

最终在bin目录下生成了 ext4和squashfs两种类型的镜像，我选择ext4镜像，解压到当前目录，使用dd命令下载到sd卡中，插上sd卡，使用dd命令将镜像烧录在sd卡起始位置。系统跑起来了：

注意： linux补丁文件不全，没有在 dts/Makefile中添加 sun8i-h3-icore5.dtb ，测试时直接再源码树修改了Makefile，有兴趣的同学可以再做一个补丁。
