remote-serial / boardctl

开发板控制工具(设计参考 ostool):每块开发板一个 TOML 配置,模块化 + 插件化架构——加传输方式/执行方式只需在插件目录丢一个文件, 改某块功能只需动对应模块。

当前接入的板卡:Sipeed LicheeRv Nano(Sophgo SG2002 / CV181x,RISC-V 玄铁 C906, U-Boot 2021.10,提示符 soph#),串口经 TCP 桥(gem12)透传,电源为小米智能插座。

快速上手

./boardctl.sh -b sg2002 run              # 列出该板的一键启动目标
./boardctl.sh -b sg2002 run hello        # 全流程:冷启动→传输→执行→断言→断电
./boardctl.sh -b sg2002 run hello -r 10  # 10 轮压测,汇总 N/10 PASS
./boardctl.sh ls                        # 列出已配置开发板
# 等价:./.venv/bin/python -m boardctl ...(任意目录可用 boardctl.sh)

架构(松耦合,单向依赖)

boardctl/
├── cli.py        命令行接线(argparse + 分发,无业务逻辑)
├── config.py     板卡 TOML 加载(不依赖其他模块)
├── session.py    U-Boot 串口会话 ← config
├── power.py      电源/冷启动   ← config, session
├── shell.py      命令执行(本机/ssh)← config
├── runner.py     run 编排       ← 上述全部 + plugins
└── plugins/      插件(目录约定自动发现,零注册代码)
    ├── transport/   传输插件:loady.py、tftp.py
    ├── executors/   执行插件:go.py、source.py、none.py、booti.py、bootm.py
    └── power/       电源插件:mijia.py(原生小米云)、command.py(命令,默认)

插件接口(接口约定写在各 __init__.py 里;插件可选声明 CFG_SECTION + DEFAULTS 自带配置默认值,TOML 优先):

传输插件(plugins/transport/xxx.py):NAME + send(cfg, path, addr) -> bool
执行插件(plugins/executors/xxx.py):NAME + build_cmd(addr) -> str | None
电源插件(plugins/power/xxx.py):NAME + set_power(cfg, on) + get_power(cfg) -> bool | None

新建插件 = 加一个文件,--method/[run].exec 立即可用,核心代码零改动。

板卡配置(boards/*.toml)

板卡配置只认 ~/.config/boardctl/boards/(搜索顺序:$BOARDCTL_BOARDS 覆盖 → ~/.config/boardctl/boards/ → 包内置示例兜底;本地/项目文件夹不参与解析)。

段	键	说明
顶层	`ssh_host`	命令模式命令的执行位置:空 = 本机;填 ssh 别名(如 `gem12`)= 经 ssh 在远端主机执行,别名/端口/用户走 `~/.ssh/config`
`[serial]`	`url` / `timeout`	串口桥 URL(本板为 `socket://...` 裸 TCP)
`[uboot]`	`prompt` / `load_addr`	提示符、默认加载地址
	`server_ip` / `ensure_server_ip`	TFTP 服务器地址;该 U-Boot 无 saveenv,连接时自动恢复
`[power]`	`method = "mijia"` + `[power.mijia]` dev_name/did	方式一·电源插件:进程内原生调用小米云(凭证复用 `~/.config/mijia-api/auth.json`,首次需 `mijiaAPI login` 扫码),不走 ssh_host
	`method = "command"` + `on_cmd`/`off_cmd`/`status_cmd`	方式二·命令插件:任意开关机 shell 命令(经 ssh_host 决定本机/远端);method 未配置时默认即此。改 `method` 一行切换
`[tftp]`	`method=remote` + `ssh_host`/`remote_dir`	scp 到远端 tftpd(gem12 的 tftpd-hpa)
	`method=local` + `local_dir`	本机临时拉起 `tftp_server.py`(UDP 69 需特权,退出自动回收)
`[loady]`	`sender`	Ymodem 发送器(Arch 为 `lrzsz-sb`)
`[run.<名字>]`	`file` / `exec` / `method` / `timeout`	一键启动目标(exec/method 即插件名;`run --repeat N` 多轮压测,每轮冷启动并汇总)
	`addr` / `entry`	加载地址 / 跳转执行地址(`go 0x...` 的目标);缺省都取 `uboot.load_addr`,加载与入口不同时分别指定
	`fdt` / `initrd`	booti 执行插件附加键:设备树地址(必需)/ initrd 地址(可选)
	`reset_before`	开头冷启动:关→开→等提示符(从任意脏状态恢复)
	`after = off/reset/none`	收尾动作
	`expect = [..]`	输出断言(子串,全命中才 PASS);`expect_re` 正则版;`fail_re` 正则禁止命中(如 panic);退出码 0/1

端到端验收

./.venv/bin/python e2e/verify_e2e.py     # reset→tftp 部署→原始流逐字节断言,两套测试

裸机测试:e2e/baremetal/(riscv64-linux-gnu-gcc,注意 DW APB UART reg-shift=2、 -fno-pie、--build-id=none)。脚本测试:e2e/script/(source 需 mkimage 的 legacy uImage 头)。构建细节与踩坑记录见 e2e/README.md。

依赖

Python 3.11+(stdlib tomllib)+ pyserial。开发安装:uv venv && uv pip install -e '.[mijia]' (依赖唯一事实来源是 pyproject.toml)。交叉构建另需 riscv64-linux-gnu-gcc、 mkimage(uboot-tools)、lrzsz。

安装与发布

# 从 PyPI 安装(发布后)
pip install boardctl            # 核心:run 全流程(loady/tftp 传输)
pip install 'boardctl[mijia]'   # + 小米云电源插件


# 发布(项目根目录)
uv build                        # 产出 dist/*.whl + *.tar.gz
uv publish --token <PyPI_API_Token>   # 建议先发 TestPyPI 演练

可选发布路径:GitHub 仓库 + Actions trusted publishing(打 tag 自动发布,免 token), 或直接 pip install git+https://...(零发布设施,适合私有/内网)。
