为 OpenWrt 加入新设备支持 // Add New Profile To OpenWrt

分类： 嵌入式

2014-09-17 14:31:17

原文地址：

最近折腾 TL-MR10U, 可直接刷 WR703N 固件, 不过 USB 不能供电, 网络, LED 正常. 所以需要修复下. 记录+教程.

假定已经有了完整 OpenWrt 开发环境. 包括编辑器, 配置好的 quilt 工具.

经过本人实践, 当前(20130522)在互联网上能找到的大部分教程都不靠谱, 或多或少有错误或者坑, 有的干脆就是错的.

配置开发环境

请参考其他文献设置开发环境. 前几篇恰好写过.

简单介绍下 quilt 工具, quilt 是用来管理代码树中的 patch 的, 嵌入式内核开发利器!

请通过软件包管理器安装 quilt. 然后写入以下配置文件到 ~/.quiltrc , 另外需要 export EDITOR="你编辑利器" . 

QUILT_DIFF_ARGS="--no-timestamps --no-index -pab --color=auto"
QUILT_REFRESH_ARGS="--no-timestamps --no-index -pab"
QUILT_PATCH_OPTS="--unified"
QUILT_DIFF_OPTS="-p"
EDITOR="emacs --no-init --quick"

准备工作

假定 ~/openwrt 是你的开发目录, 建议直接在 git branch 下开发.

假设之前已经编译过 bin, 有完整的 .config 和 toolchain.

建立开发 branch: (git 教程自行脑补) 

~/openwrt$ git checkout -b add-tl-mr10u-support

清理 tmp 目录!!!!!! 这个是大坑. 直接删除. 

~/openwrt$ rm -rvf tmp/

修改 OpenWrt 代码

进入设备硬件目录: 

~/openwrt$ cd target/linux/ar71xx

修改以下文件, 里面涉及到 TL-MR10U 固件中设备ID的部分, 是 0x00100101, 这个值从 tp-link 官方网站下载的固件中可以获得.

  • base-files/etc/diag.sh
  • base-files/etc/uci-defaults/02_network
  • base-files/lib/ar71xx.sh
  • base-files/lib/upgrade/platform.sh
  • config-3.8
  • generic/profiles/tp-link.mk
  • image/Makefile

新建文件: files/arch/mips/ath79/mach-tl-mr10u.c , 内容参考 TL-WR703N 设备的文件 mach-tl-wr703n.c, 修改所有出现 wr703n, WR703N 等等大小写混合的部分, emacs 无痛苦完成.

添加 Linux patch

这里就完成了 OpenWrt 的设备支持代码. 为了支持我们的设备, Linux 代码树的部分文件也需要做改动, OpenWrt 采用了 patch 的方式实现.

回退到根目录 ~/openwrt .

清理并准备 patch 树: 

~/openwrt$ make target/linux/{clean,prepare} # 后面可加 V=s QUILT=1 参数, 表示静默无输出

进入内核代码目录(其中版本号可能与你的不一致): 

~/openwrt$ cd build_dir/target-mips_r2_uClibc-0.9.33.2/linux-ar71xx_generic/linux-3.8.12/

这里就是内核代码树了, 里面的代码是已经打过所有 patch 的, 可以用 quilt push 检查看是不是这样: 

$ quilt push
File series fully applied, ends at patch platform/902-unaligned_access_hacks.patch

这条输入也告诉我们, 当前最顶的 patch 是 platform/902 (这个是坑啊, 官方文档不带 platform 前缀, 是错的).

为我们的 TL-MR10U 新建个 patch: 

$ quilt new platform/920-add-tl-mr10u-support.patch

选择的数字需要大于刚才的那个 902, 然后 quilt 会自动把这个 patch 设置为当前 patch, 所有的改动都针对这个 patch.

然后就是增加代码了 

$ quilt edit arch/mips/ath79/Kconfig
$ quilt edit arch/mips/ath79/Makefile
$ quilt edit arch/mips/ath79/machtypes.h

至于怎么改, 参考这些文件里其他硬件的配置, 基本上说 copy TL-WR703N 的就可以了. 保证不重不漏.

然后验证下修改的内容: 

$ quilt diff # 查看 diff
$ quilt refresh # 保存所有 diff 到 patch 文件

这个时候我们的 patch 文件还在 build_dir 里, 大概位置是 patches/platform/ 下. 需要同步到 OpenWrt 代码树. 

# 退回到顶层工作目录, 执行:
~/openwrt$ make target/linux/update V=s

同步完成后, patch 文件会出现在 target/linux/ar71xx/patches-3.8/ 下.

固件工具代码修改

OpenWrt 包含一个 TP-LINK 固件小工具, tools/firmware-utils/src/mktplinkfw.c , 里面包含 TP-LINK 固件 bin 文件的结构和 md5 hash 验证算法.

修改内容参考 WR703N 就好.

查看效果

这里应该已经完成了所有操作. 可以编译了 

# 再次记得, 删除 tmp 目录
~/openwrt$ rm -rvf tmp/
~/openwrt$ make menuconfig
.....
自己编译

所有修改文件
