【在 MBP（Apple M1 Pro）上捣鼓友善 nanoPi R5S】之构建 rkdeveloptool
在种草了很多天之后，最近终于在淘宝下单了友善 nanoPi R5S。
选择友善 nanoPi R5S 有两点主要理由：
1. 自带 EMMC 存储，可以使用 RockChip 提供的 MaskRom 模式直接连线烧系统，不依赖 TF 卡（我觉得 TF 卡太累赘了，买普通的又慢又不稳定，对于我这种新手来说，多一个配件就多一个问题）；
2. 带一个 M.2 M-Key 的插槽，方便我后续加存储存一些家庭照片（不需要什么扩展板、连线，直接在 CNC 铝壳里，很利索）。
我的主力电脑是一台 MBP(Apple M1 Pro)，因此在下单前选配件的时候，我犹豫是否需要 USB-A 到 USB-A 连接线，要这个线的话，我还得买一个USB-A 到 Type-C 的转接。能不能直接使用手头就有的 USB-A 到 USB-C 线呢？基本买手机、充电器都会带一根，家里已经到处都是了。
遂咨询客服。
- “能不能用现在很常见的 USB-A 到 USB-C 的线直连 MBP？”
- “线可以，MacOS 不提供支持”
意思就是线是行的，但是用 MacOS 的话店家不提供支持。
🤔
不甘结束的我，接下来查到了这个：Install Rockchip flashing tools
由它来到了 RockChip 在 GitHub 开源的 rkdeveloptool 仓库：https://github.com/rockchip-linux/rkdeveloptool
啊哈，看来把它在 Mac 上编译一下，就和 Windows 上一样了，就可以直连 MaskRom 的 R5S，烧系统捣鼓起来……
按照 Install Rockchip flashing tools 的指引，开始尝试本地编译 rkdeveloptool
brew install automake autoconf libusb
git clone git@github.com:rockchip-linux/rkdeveloptool.git
cd rkdeveloptool
autoreconf -i
./configure
make
在最后 make的时候，报错了：

看起来是 sprintf 方法已经废弃了，建议使用 snprintf 替代。嗯，🤔，作为新手还是先不改代码了，先查一下这个问题怎么绕过。
在项目仓库找到一个 Issus #75，移除 Makefile.am 里的 -Werror，然后重新执行：
autoreconf -i
./configure
make
项目根目录出现了 rkdeveloptool 可执行程序，执行：
rkdeveloptool -v
输出
rkdeveloptool ver 1.32
成功了，😄
现在，就等着 R5S 到货了。
