Ubuntu下编译TPLink TL-WR743N V2的Openwrt固件-替代法

此方法是在TL-WR703N的源码上进行修改，用743替代703，原703失效

环境要求

编译一个可以安装的OpenWrt固件镜像文件（大约8MB大小的），你需要：

• 一个纯净的OpenWrt编译系统大约需要200MB的空间。
• 一个包含feeds的OpenWrt编译系统大约需要300MB的空间。
• 编译feeds中的软件包大约需要2.1GB的空间用于存放下载来的源代码。
• 构建OpenWrt并生成固件文件需要大约3-4 GB的空间。
• 编译OpenWrt需要大约1-4 GB的内存。

以非root用户来进行工作

1、下载源码

git clone git://git.openwrt.org/15.05/openwrt.git

从最新代码恢复为15.05的主干代码

git checkout 483dac821788b457d349233e770329186a0aa860

openwrt/include/version.mk文件可以查看版本号

VERSION_NUMBER:=$(if $(VERSION_NUMBER),$(VERSION_NUMBER),15.05)

2、配置

cd openwrt

下载并安装所有可用的"feeds"，这是为了下载和安装让luci之类的第三方包的源码，如果不进行这步的话配置菜单是没有非openwrt的包给你选的

./scripts/feeds update -a

./scripts/feeds install -a

运行下面的命令让OpenWrt编译系统检查你的编译环境中缺失的软件包:
make defconfig
make prereq

然后
make menuconfig

选编译的目标系统（Atheros AR7XXX架构，profile为703N）：

选缺省组件：

编辑完成后点击“save”保存配置文件：

3、修改源文件

make前修改如下文件：

1）增加网口：703只有一个网口，743有1个WAN，4个LAN口，粗体为修改部分

openwrt\target\linux\ar71xx\files\arch\mips\ath79\mach-tl-wr703n.c

ath79_register_usb();

//ath79_init_mac(ath79_eth0_data.mac_addr, mac, 0);
//ywb
ath79_init_mac(ath79_eth0_data.mac_addr, mac, 1);
ath79_init_mac(ath79_eth1_data.mac_addr, mac, -1);
ath79_register_mdio(0, 0x0);
//ath79_register_eth(0);
//ywb
/* LAN ports */
ath79_register_eth(1);

/* WAN port */
ath79_register_eth(0);

if (sec_ethernet)

2）修改指示灯，粗体为修改部分

修改openwrt\target\linux\ar71xx\files\arch\mips\ath79\mach-tl-wr703n.c

3)修改主机型号为743

替换WEB页面的显示型号为743

openwrt/target/linux/ar71xx/base-files/lib/ar71xx.sh

echo "$AR71XX_BOARD_NAME" > /tmp/sysinfo/board_name

  if echo $AR71XX_MODEL|grep 703; then
AR71XX_MODEL="TP-LINK TL-WR743N v2"
fi

echo "$AR71XX_MODEL" > /tmp/sysinfo/model

 

4、执行编译

对于第一次编译，请不要开多线程。。。。因为不好排错
make V=99

如果第一次编译成功的话，之后的编译可以充分发挥多核心的优势了

首先执行：
ulimit -s 10240
这个命令是防止爆栈

对make加入多线程编译支持
make V=99 -j线程数
速度比单线程快N倍

第二次编译命令示例：

rm .config
rm -rf tmp
make defconfig
make menuconfig
ulimit -s 10240
make V=99 -j8

 

如修改了源文件，需要在build目录删除.o文件，并将修改后的文件拷贝到build相应目录，如：

/openwrt/build_dir/target-mips_34kc_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.18.36/arch/mips/ath79/mach-tl-wr703n.c
