注意：以下所有命令行操作都是在 用户模式 下进行，需要 root 权限的地方会使用 sudo 命令。

1 背景简介

NXP 提供的 LPCScrypt 工具支持 Linux、macOS 和 Windows，详情阅读 LPCScrypt 上的介绍。

官网给的 Linux 版本的 lpcscrypt-2.1.2_57.x86_64.deb.bin 工具看名称是 Debian/Ubuntu 衍生版才能安装使用。

Arch 用户或其他 Linux 发行版用户想使用怎么办？

2 待打包软件分析

本节先分析原始包：lpcscrypt-2.1.2_57.x86_64.deb.bin，拆解包结构，得到核心二进制工具。

第1步，注册 NXP 官网下载相应的 Linux 版本文件，访问 NXP LPCScrypt 进行注册即可。

第2步，用文本编辑器打开查看里面的内容（内容较多，大体翻阅一下就好）：

可以看到，前半部分是 shell 脚本，从 499 行开始就是乱码了。

第 437 行有这个提示：

  1. offset=`head -n 498 "$0" | wc -c | tr -d " "`

推测 NXP 是使用 gzexe 进行了压缩和简单的加密处理

第3步，开始解密 lpcscrypt-2.1.2_57.x86_64.deb.bin：

  1. $ tail -n +499 lpcscrypt-2.1.2_57.x86_64.deb.bin > lpcscrypt-2.1.2_57.x86_64.deb

得到一个 deb 包（不知道是不是正常的 deb 包，进行下一步验证）

第4步，尝试当 deb 解压

  1. $ bsdtar -xf lpcscrypt-2.1.2_57.x86_64.deb

解压成功（狗头保命。如果不是 deb，可能得尝试其他格式了，这里不做进一步说明。

第5步，解压 data.tar.gz

  1. $ mkdir -p build
  2. $ tar -xf data.tar.gz -C build

最后，顺利得到了 NXP 的编译后的二进制文件：

3 编写 PKGBUILD 打包脚本

接下来，按 Arch 的打包规范编写 PKGBUILD 打包脚本。

注意：需要根据 NXP 的介绍需要依赖最新版 jlink 软件包，Arch 下是 jlink-software-and-documentation，其他 Linux 可能在软件商店有，也可能没有，那就需要自行去 Segger 官网下载 Jlink 的软件包了。

4 编译 PKGBUILD 并安装验证

如果需要更新 PKGBUILD 中sha256sums 校验值，请运行：

  1. $ updpkgsums

然后创建 .SRCINFO 文件：

  1. $ makepkg --printsrcinfo > .SRCINFO

接着编译 PKGBUILD：

  1. $ makepkg -sf
  2. ==> 正在创建软件包：lpcscrypt-bin 2.1.2-1 (2021年07月04日 星期日 14时04分10秒)

  32.                           +wN==width of fill_value, where N is 1, 2 or 4
  33.                 program file or value into flash at baseAddress
  34.     verify      verify [+c|+i|+wN] (<file>|<fill_value>) <baseAddress>

  62. /dev/ttyUSB0
  63. /dev/ttyACM0

5 发布 AUR 包

接下来把打好的软件包上传到 AUR 仓库。

首先，从 AUR 上创建一个空仓库：

  1. $ git clone ssh://aur@aur.archlinux.org/lpcscrypt-bin.git

添加刚才的 PKGBUILD .SRCINFO 文件到仓库中：

  1. $ git add PKGBUILD
  2. $ git add .SRCINFO
  3. $ cat > .gitignore << EOF
  4. *
  5. *.*
  6. EOF
  7. $ git add .gitignore -f
  8. $ git commit -am "Update lpcscrypt-bin"
  9. $ git push

发布后，就得到了 lpcscrypt-bin AUR 包。
