# J-Link GDB 调试

## 适用场景

- 用户希望通过 SEGGER J-Link 探针调试 Cortex-M 类目标。
- 工作区中已有 `ELF` 和 J-Link 探针。
- 烧录或串口监视流程表明,需要进一步查看断点、停核控制、寄存器或回溯信息。
- 需要使用 SWO 输出捕获功能。
- 需要在调试前确认 JLinkGDBServer 和 GDB 环境是否就绪。

## 必要输入

- 一份带符号的 `ELF`,或包含 `artifact_path` 的 `Project Profile`。
- `--device` 参数指定目标芯片型号(J-Link GDB Server 要求必须指定)。
- 可选调试模式:`download-and-halt`、`attach-only`、`crash-context`。
- 可选的 GDB 可执行文件路径。

## 自动探测

- 默认模式为 `download-and-halt`;只有用户显式要求附着调试或崩溃现场检查时才切换。
- GDB 由脚本自动探测,优先级为:显式用户输入、`Project Profile`、`arm-none-eabi-gdb`、`gdb-multiarch`。
- JLinkGDBServer 按配置文件、PATH、常见安装路径顺序查找。
- 做符号级调试必须有 `ELF`。若只有 `HEX` 或 `BIN`,应阻塞并要求提供匹配 `ELF`。

## 执行步骤

1. 先阅读 [references/usage.md](references/usage.md),确认本次是环境探测,还是执行调试会话。
2. 若不确定环境是否就绪,先运行自带脚本 [scripts/jlink_debugger.py](scripts/jlink_debugger.py) 的 `--detect` 模式确认。
3. 根据用户意图选择调试模式:`download-and-halt`(默认)、`attach-only` 或 `crash-context`。
4. 使用 `--elf` + `--device` 启动调试,可选 `--interface` 和 `--port`。
5. 需要 SWO 输出时,使用 `--swo` 参数。
6. 读取脚本输出的调试结果,重点关注寄存器状态、回溯帧和 Fault 寄存器。

## 失败分流

- 当缺少 `JLinkGDBServerCLExe` 或兼容 GDB 时,返回 `environment-missing`。
- 当没有可用的 `ELF` 时,返回 `artifact-missing`。
- 当 JLinkGDBServer 无法连接目标板时,返回 `connection-failure`。
- 当设备名不被 J-Link 识别或配置不一致时,返回 `project-config-error`。
- 当会话可以建立,但无法停核、加载或得到可信回溯时,返回 `target-response-abnormal`。
- 当 `--device` 缺失且无法从工作区推断时,返回 `ambiguous-context`。

## 平台说明

- JLinkGDBServer 在 Linux/macOS 下为 `JLinkGDBServerCLExe`,Windows 下为 `JLinkGDBServerCL.exe`。
- 默认 GDB 端口为 2331(J-Link 默认),可通过 `--port` 修改。
- 自带脚本使用 Python 标准库和 subprocess,跨平台兼容。
- SWO 功能为 J-Link 独有,可捕获 ITM printf 输出。

## 输出约定

- 输出调试模式、JLinkGDBServer 命令、GDB 可执行文件、`ELF` 路径和关键观察结论。
- 在 `Project Profile` 中保留 `artifact_path`、`artifact_kind`、`gdb_executable`、`jlink_device`。
- 当复位后或继续运行后下一步是观察运行行为时,推荐 `serial-monitor`。

## 交接关系

- 当目标恢复运行后,需要继续观察运行期日志时,将成功会话交给 `serial-monitor`。
- 当用户需要 RTOS 线程感知调试时,将会话交给 `rtos-debug`。

Questions about debug-jlink

What does the debug-jlink skill do?
面向 AI 编程助手的嵌入式开发技能集,为大模型提供 MCU 固件开发全流程能力。涵盖多工具链构建(Keil / IAR / CMake / PlatformIO)、烧录、GDB 调试、串口监视、Modbus / CAN / VISA 协议调试、外设驱动适配及流水线编排,支持 Linux、macOS、Windows 三平台。
Is debug-jlink safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can debug-jlink access on my machine?
The audit observed that it reaches the network. Each of those is consistent with what it says it does. Secrets in the source: none found.
How current is this page?
The grade is for one exact copy of the source (f2eee4d05246), read on 2026-10-28. The repository is watched, and a new audit runs when it changes — this is the first audit.
