# TCP2UART 工程调试指南
# TCP2UART 调试指导
## 1. 适用范围
本指南面向当前 `TCP2UART` 工程，目标是指导以下调试场景：
本指导面向当前 `TCP2UART` 工程，覆盖以下四类调试场景：
1. `STM32F103R8T6 + CH390D` 的基础 bring-up
2. CH390D 的寄存器读写、链路检测、中断与收发调试
3. `lwIP RAW API + NO_SYS=1` 路线下的网络链路问题定位
4. UART 透传与 TCP 双链路联调
2. `SEGGER RTT`、异常陷阱与主循环运行状态确认
3. `USART1` 配置口、`USART2/USART3` 数据口与 `MUX / NET / LINK[idx]` 协议联调
4. `TCP Server / TCP Client / UART` 三层数据通路联调与问题隔离
本指南默认基线：
本指导默认基线如下：
1. 当前工程已切换为裸机主循环架构
2. CH390 运行时访问统一由 `ch390_runtime` 持有
3. 调试输出通过 `SEGGER RTT`
4. 当前代码已经通过 `MDK-ARM` 构建，且构建结果为 `0 error / 0 warning`
1. 当前工程采用裸机主循环架构，未使用 FreeRTOS 参与主业务调度
2. `CH390` 运行时访问统一由 `ch390_runtime` 持有
3. 调试输出统一使用 `SEGGER RTT`
4. 当前应用层协议模型已经收敛到 `MUX / NET / LINK[idx]`
5. 当前代码应以 `MDK-ARM` 工程构建结果为准，而不是 `CMake + MSVC` 结果
## 2. 当前工程调试边界
---
截至当前版本，工程状态应按以下层级理解：
## 2. 当前工程边界与真实状态
1. MCU 启动、系统时钟、RTT、TIM4 心跳与主循环均可正常工作
2. CH390D 已恢复基础寄存器读写，不再处于“全 `0xFF` / 全 `0x0000`”阶段
3. 实机已读到可信芯片与 PHY 标识：`VID=0x1C00`、`PID=0x9151`、`REV=0x2B`、`PHYID1=0x7371`、`PHYID2=0x9011`
4. 实机已观察到主机 Realtek USB GbE 网卡为 `Connected 100 Mbps`，且设备侧 `lwIP netif` 标志包含 `LINK_UP`
5. 当前调试重点不再是“SPI 是否完全不通”，而是：
- 默认配置是否完整生效
- MAC 写入与回读是否一致
- PHY 协商、`INT/LINK/RX/TX` 是否进入正常工作态
- 网络链路与 UART 透传是否稳定协同
在进入现场调试前，先统一以下工程边界，避免沿用过时结论：
因此，后续调试应避免继续沿用“CH390 完全无响应”的旧结论，而应转入功能链路验证。
1. 当前项目的主要软件路径已经切换为：
- `NET`：网络基础参数
- `LINK[idx]`：链路配置记录
- `MUX`：数据口承载模式
2. 对外 AT 配置面应只围绕以下命令展开：
- `AT`
- `AT+?`
- `AT+QUERY`
- `AT+MUX`
- `AT+NET`
- `AT+LINK`
- `AT+SAVE`
- `AT+RESET`
- `AT+DEFAULT`
3. 当前 `CH390D` 的历史“全 `0xFF` / 全 `0x0000`”结论不应再直接沿用。
4. 已有结论表明：
- MCU 启动、RTT、主循环、TIM4 心跳路径可工作
- `CH390D` 基础寄存器读写与 `lwIP netif` 基本链路已经打通过一次
- 真实硬件侧曾定位到 `CH390D` 供电滤波电容虚焊问题
5. 因此，当前调试重点不再是“CH390 是否完全不通”，而是：
- 启动阶段是否稳定
- `MUX / NET / LINK[idx]` 协议是否与代码一致
- UART / TCP / CH390 三层通路是否协同稳定
- 参数保存、复位和恢复流程是否可靠
## 3. 代码入口与责任边界
---
### 3.1 启动路径
## 3. 代码入口与调试责任边界
当前 CH390 相关启动链路为：
### 3.1 启动与主循环入口
1. `main()`
2. `App_Init()`
3. `lwip_netif_init()`
4. `ethernetif_init()` / `low_level_init()`
5. `ch390_runtime_init()`
6. `ch390_gpio_init()`
7. `ch390_spi_init()`
8. `ch390_hardware_reset()`
9. `ch390_runtime_probe_identity()`
10. `ch390_default_config()`
11. `ch390_set_mac_address()` / `ch390_get_mac()`
12. `ch390_interrupt_init()`
以下代码路径是 bring-up 的第一现场：
### 3.2 运行时责任边界
1. `Core/Src/main.c`
- `main()`：总启动入口
- `SystemClock_Config()`：时钟初始化
- `App_Init()`：应用层初始化
- `App_Poll()`：主循环核心路径
- `BootDiag_ReportCh390()`：启动阶段 CH390 诊断输出
2. `Core/Src/stm32f1xx_it.c`
- 故障与中断入口
- `USART1/2/3`、`EXTI0`、DMA 回调等联调关键入口
当前代码约束如下：
### 3.2 CH390 责任边界
当前 CH390 调试必须遵守以下责任边界：
1. `Drivers/CH390/CH390_Interface.c`
- 只负责底层 GPIO、SPI 与寄存器/内存访问
- 当前寄存器读写路径使用 `Mode 3 + bytewise exchange` 事务模型
- 只负责 GPIO / SPI / 寄存器与内存事务
2. `Drivers/CH390/CH390.c`
- 只负责芯片级 helper，例如 `default_config`、PHY 访问、MAC 操作
- 只负责芯片级 helper，例如默认配置、PHY、MAC 读写
3. `Drivers/CH390/ch390_runtime.c`
- 唯一的 CH390 运行时拥有者
- 负责初始化、链路查询、IRQ 消费、RX/TX 服务
- 唯一的运行时拥有者
- 负责初始化、链路检查、IRQ 消费、RX/TX 服务与诊断快照
4. `Drivers/LwIP/src/netif/ethernetif.c`
- 不再直接承担复杂 CH390 运行时事务，只做 netif glue
- 只承担 netif glue 与轮询桥接，不应重新下沉复杂 CH390 运行时事务
5. `Core/Src/main.c`
- 启动后只通过 `BootDiag_ReportCh390()` 读取 runtime 提供的启动快照
- 启动后只通过 runtime 对外暴露的诊断与轮询接口工作
调试时应优先维护这个边界，不要重新把原始寄存器访问散落回 `main.c` 或 EXTI 中断中。
调试时不要把原始 CH390 寄存器访问重新散回 `main.c`、中断或多个业务层。
## 4. 当前硬件连接事实
### 3.3 配置口与业务口边界
根据 `PCB/SCH_Schematic1_2026-03-26.pdf`，CH390D 关键硬件事实如下：
1. `USART1`
- 配置口
- 负责接收 `AT` 命令
- 当前接收逻辑在：
- `Core/Src/main.c` 的 `App_PollUart1ConfigRx()`
- `Core/Src/stm32f1xx_it.c` 的 `HAL_UART_RxCpltCallback()`
- `App/config.c` 的 `config_uart_rx_byte()` / `config_process_at_cmd()`
2. `USART2 / USART3`
- 数据口
- 负责普通透传或 MUX 承载
- 当前入口在 `App/uart_trans.c`
1. MCU 与 CH390D 的连接关系：
- `PA4 -> CH_CS -> U4.SCS`
- `PA5 -> CH_CLK -> R10(22Ω) -> U4.SCK`
- `PA6 <- CH_SDO <- U4.SDO/MISO`
- `PA7 -> CH_SDI -> U4.SDI/MOSI`
- `PB0 <- CH_INT <- U4.INT`
- `PB1 -> CH_RST -> R8(470Ω) -> U4.RSTB`
2. CH390D 使用 `25MHz` 晶振 `X2`
3. CH390D 存在独立相关电源域：
- `VDDK`
- `AVDD33/VDDIO`
- `AVDD33`
4. CH390D 周边去耦电容包括 `C18/C20/C21/C22`
5. 原理图上未看到独立的 `MISO` 外部上拉电阻
6. 当前代码中的 `ch390_hardware_reset()` 采用：
- 复位前等待 `10ms`
- `RSTB` 拉低 `3ms`
- 释放后等待 `50ms`
---
调试时必须优先在 **CH390 芯片脚侧** 量测，而不是只在 MCU GPIO 侧判断。
## 4. 当前硬件与调试工具基线
## 5. 推荐调试顺序
### 4.1 核心硬件对象
### 5.1 P0：先确认基础条件
1. MCU：`STM32F103R8T6`
2. 以太网芯片：`CH390D`
3. 配置串口：`USART1`
4. 数据串口：`USART2 / USART3`
5. 调试输出：`SEGGER RTT`
每次进入功能调试前，先确认以下最小基线：
### 4.2 构建与下载基线
1. `MDK` 可成功构建，且当前日志为 `0 error / 0 warning`
2. RTT 可输出启动日志
3. `BootDiag_ReportCh390()` 能打印出 `VID/PID/REV/NSR/NCR/RCR/IMR/INTCR/GPR/ISR`
4. `App_Poll()` 正常运行，LED 心跳正常
当前建议优先使用以下工程与产物：
### 5.2 P1：验证 CH390 初始化状态
1. `MDK-ARM/TCP2UART.uvprojx`
2. `MDK-ARM/TCP2UART/TCP2UART.axf`
3. `MDK-ARM/TCP2UART/TCP2UART.hex`
4. `MDK-ARM/TCP2UART/TCP2UART.map`
5. `MDK-ARM/TCP2UART/TCP2UART.build_log.htm`
6. `build_keil.log`
优先检查以下问题：
说明：
1. `ETH init: probe/default/mac/getmac/irq/done` 是否完整打印
2. `VID/PID/REV` 与 PHY ID 是否稳定、可信
3. MAC 写入与 `ch390_get_mac()` 回读是否一致
4. `RCR/IMR/INTCR/GPR` 是否进入预期工作态
5. `link_up` 与 `lwIP netif` 的 `LINK_UP` 标志是否与物理网线状态一致
1. 当前 `CMake configure` 可以完成，但 `CMake + MSVC` 不适合作为 STM32/CMSIS 的最终构建验收依据。
2. 若需要验证“当前代码是否真实可编译”，优先看 `MDK-ARM` 构建产物与日志。
如这一层失败，优先回到芯片侧量测：
### 4.3 常用调试工具
1. `Keil MDK-ARM`
2. `ST-Link / J-Link`
3. `SEGGER RTT Viewer`
4. `PowerShell`
5. `tools/start_tcp_debug_server.ps1`
6. `tools/tcp_debug_server.py`
---
## 5. 启动阶段调试顺序
建议按 P0 ~ P5 顺序推进，不要跳层。
### 5.1 P0：确认最小基础条件
每次现场调试前，先确认：
1. `MDK-ARM` 可构建并产出新的 `axf/hex/map`
2. 板卡可正常下载与复位
3. RTT 可连接并看到启动输出
4. LED 心跳可工作
5. `App_Poll()` 已经进入稳定轮询
这一层若失败，不要进入网络或协议调试。
### 5.2 P1：确认启动日志与 trap 状态
上电或复位后，优先看 RTT 输出中是否出现：
1. `TCP2UART boot`
2. 若 HSE 启动失败，则会出现：
- `WARN: HSE start failed, fallback to HSI PLL`
3. `BootDiag_ReportCh390()` 输出的 CH390 诊断与网络配置快照
若发生异常，优先观察是否打印：
1. `TRAP: Error_Handler`
2. `TRAP: HardFault_Handler`
3. `TRAP: MemManage_Handler`
4. `TRAP: BusFault_Handler`
5. `TRAP: UsageFault_Handler`
当前 trap 统一收敛到：
1. `Core/Src/main.c` 的 `Debug_TrapWithRttHint()`
2. 它会打印 RTT、执行 `__BKPT(0)` 并停住
因此，若 RTT 中出现 `TRAP:`，应立即接调试器看断点现场，而不是继续盲猜高层逻辑。
### 5.3 P2：确认 CH390 初始化链路
启动阶段应重点关注 `Drivers/CH390/ch390_runtime.c` 中初始化阶段日志，理想情况下应能依次看到：
1. `ETH init: gpio`
2. `ETH init: spi`
3. `ETH init: reset`
4. `ETH init: probe`
5. `ETH init: default`
6. `ETH init: mac`
7. `ETH init: getmac`
8. `ETH init: irq`
9. `ETH init: done`
此阶段重点判定：
1. `VID / PID / REV` 是否可信
2. PHY 寄存器是否稳定可读
3. MAC 写入与回读是否一致
4. `link_up` 是否与真实网线状态一致
若这一层失败，优先做硬件侧量测，而不是先改业务层：
1. `RSTB`
2. `CS`
3. `SCK`
4. `MOSI`
5. `MISO`
6. `VDDK / AVDD33/VDDIO / AVDD33`
6. `INT`
7. `VDDK`
8. `AVDD33 / VDDIO / AVDD33`
9. `XI / XO`
### 5.3 P2：验证 IRQ 与链路检测
---
在基础寄存器读写可信后，重点验证：
## 6. USART1 配置口调试
1. `PB0/EXTI0` 是否能接收到 CH390 的 `INT`
2. `ISR_LNKCHG` 发生时，`ch390_runtime_poll()` 是否正确更新链路状态，不再依赖阻塞式 `HAL_Delay(65)`
3. `ethernetif_check_link()` 与 `ch390_runtime_check_link()` 的结果是否一致
4. 必须区分“启动快照中的 `g_diag.link_up`”与“主循环中实时更新后的 `netif->flags & NETIF_FLAG_LINK_UP`”
### 6.1 当前命令面
### 5.4 P3：验证 RX/TX 数据通路
根据当前代码与手册，配置口应围绕以下命令验证：
在 `link_up` 可信后，再继续验证数据通路：
1. `AT`
2. `AT+?`
3. `AT+QUERY`
4. `AT+MUX=...`
5. `AT+MUX?`
6. `AT+NET=...`
7. `AT+NET?`
8. `AT+LINK=...`
9. `AT+LINK?`
10. `AT+SAVE`
11. `AT+RESET`
12. `AT+DEFAULT`
1. 先确保主机网卡与设备处于同一子网；当前联调基线曾使用主机 `192.168.31.1` 与设备 `192.168.31.x`
2. `ch390_runtime_input()` 是否能稳定读取 `RX SRAM`
3. `rx_status / rx_len` 是否合理
4. `ch390_runtime_output()` 是否能正确等待 `TCR_TXREQ` 清零并发送帧
5. 网络端与 UART2/UART3 透传是否联通
### 6.2 现场关键规则
### 5.4.1 最小 TCP 调试工具
根据已有联调记录，配置口最关键的 bench 规则是：
当需要验证 `TCP server(8080)` 到 `TCP client(8081)` 的原始桥接行为时，优先使用仓库内置的最小工具，而不是直接依赖 VOFA 这类带协议/显示假设的上位机工具。
1. 当前现场验证时，配置命令必须保证以换行完成帧。
2. 若主机侧发送方式不对，现象会很像“配置口完全无响应”。
3. 因此，配置口不响应时，第一优先级不是改 parser，而是先验证主机端发送格式与接线。
推荐工具如下：
### 6.3 最小验证步骤
建议按以下顺序验证：
1. 连接 `USART1`
2. 先发 `AT`
3. 再发 `AT+QUERY`
4. 再发 `AT+NET?`
5. 再发 `AT+LINK?`
6. 修改一个最小参数，例如：
- `AT+MUX=1`
7. 执行：
- `AT+SAVE`
- `AT+RESET`
8. 复位后再次查询，确认配置是否保留
### 6.4 持久化失败时怎么查
优先检查以下路径：
1. `App/config.c`
- `config_save()`
- `config_load()`
- `config_set_defaults()`
2. `App/flash_param.c`
- Flash 解锁
- 页擦除
- 半字编程
- 写后校验
3. 参数页地址：
- `0x0800FC00`
不要在还没证明 `AT+SAVE` 已真正被接受之前，就直接把 `Flash 全 FFFFFFFF` 归因到 Flash 驱动错误。
---
## 7. MUX / NET / LINK[idx] 联调指导
### 7.1 协议总则
当前协议必须按以下模型理解：
1. `MUX`：全局数据承载模式开关
2. `NET`：IP / Mask / GW / MAC
3. `LINK[idx]`：链路配置项
固定链路索引映射为：
1. `LINK[0] = S1`
2. `LINK[1] = S2`
3. `LINK[2] = C1`
4. `LINK[3] = C2`
固定端点编码为：
1. `C1 = 0x01`
2. `C2 = 0x02`
3. `UART2 = 0x04`
4. `UART3 = 0x08`
5. `S1 = 0x10`
6. `S2 = 0x20`
### 7.2 MUX 数据口规则
当 `MUX=1` 时，数据口应使用 MUX 帧。
重点规则：
1. `DSTMASK=0x00` 表示系统控制帧
2. 控制帧中的 AT 文本必须严格按手册要求结束
3. 普通数据帧走业务转发路径，不应进入配置解析器
### 7.3 调试时重点检查什么
若怀疑 `MUX` 模式不工作，优先检查：
1. `App/uart_trans.c`
- `uart_mux_try_extract_frame()`
- `uart_mux_encode_frame()`
2. `Core/Src/main.c`
- `App_RouteMuxUartTraffic()`
- `App_RouteRawUartTraffic()`
- `App_RouteTcpTraffic()`
3. `App/config.c`
- `config_build_response_frame()`
- `config_process_at_cmd()`
推荐最小 MUX 联调顺序：
1. 先在 `MUX=0` 下跑通原始透传
2. 再切换 `MUX=1`
3. 先发一个控制帧，确认 `DSTMASK=0x00` 路径可通
4. 再发一个单目标数据帧，例如只打到 `S1`
5. 最后验证多目标位图转发

## 8. TCP / UART / CH390 联调顺序
### 8.1 先做链路，再做业务
在 `CH390` 初始化、链路和 IRQ 未被证明稳定前，不要先调高层 TCP/UART 业务。
### 8.2 推荐顺序
建议按以下顺序推进：
1. RTT 启动与 trap 状态正常
2. CH390 启动日志完整
3. 链路检测可信
4. `TCP server` / `TCP client` 建链可信
5. UART 原始透传可信
6. 再切入 `MUX` 模式联调
### 8.3 最小 TCP 调试工具
当需要验证板子是否真的把 payload 发到主机时，优先使用仓库内置最小工具：
1. `tools/tcp_debug_server.py`
- 纯 Python 原始 TCP 服务端
- 可直接打印连接、收包、文本视图和十六进制视图
- 适合确认“板子到底有没有把原始 payload 发到 PC 的 8081 端口”
- 打印连接、收包、文本视图和十六进制视图
2. `tools/start_tcp_debug_server.ps1`
- PowerShell 包装脚本
- 会先清理本机 `8081` 端口上的现有监听，再启动 Python 调试服务端
- 适合避免 `ncat`、遗留 Python、VOFA 等进程抢占 `8081`
- 会先清理冲突监听，再启动 Python 服务端
推荐使用方法：
推荐命令：
```powershell
powershell -ExecutionPolicy Bypass -File ".\tools\start_tcp_debug_server.ps1" -Port 8081 -NoStdin
```
如需回显模式：

python .\tools\tcp_debug_server.py --host 0.0.0.0 --port 8081 --no-stdin
```
使用该工具时，推荐调试顺序如下：
### 8.4 推荐验证方法
1. 先关闭 VOFA、`ncat` 和其它可能占用 `8081` 的进程
2. 启动 `start_tcp_debug_server.ps1`
3. 再让板子连接 `192.168.31.1:8081`
4. 然后从 PC 连接板子的 `192.168.31.100:8080`，发送一段明确文本，例如 `hello`
5. 观察 Python 工具是否打印：
- 客户端已连接
- 收到的原始字节长度
- 文本视图与十六进制视图
3. 让板子连接主机 `TCP client` 目标端口
4. 再从主机连接板子的 `TCP server` 端口发送固定测试文本
5. 同时观察：
- Python 工具是否收到连接与 payload
- 板子 RTT 是否出现连接或错误信息
如果板子 RTT 显示 `TCP client connected to ...:8081`，但 Python 工具没有任何连接提示，优先检查本机端口占用：
若板子 RTT 显示已连接，但主机工具无数据，优先检查本机端口占用而不是先改板端逻辑。
```powershell
Get-NetTCPConnection -LocalPort 8081 -ErrorAction SilentlyContinue |
Select-Object LocalAddress,LocalPort,RemoteAddress,RemotePort,State,OwningProcess
```
---
若存在多个监听者，优先清理后再测，否则板子可能连接到错误的本机进程。
## 9. 异常、卡死与假死排查
### 5.5 P4：验证系统级联调
### 9.1 看到 `TRAP:` 时怎么做
最终再验证：
1. 先记录 RTT 中的 trap 标签
2. 立刻用调试器查看当前 PC / LR / 调用栈
3. 结合 `Core/Src/stm32f1xx_it.c` 中对应 handler 定位异常类型
1. TCP Server 与 UART2 双向透传
2. TCP Client 与 UART3 双向透传
3. 配置保存、复位与 MAC 生效路径
4. 长时间运行稳定性
### 9.2 没有 `TRAP:` 但系统不工作时怎么做
## 6. 推荐的现场观测点
若没有 `TRAP:`，但系统表现异常，应优先区分以下情况：
### 6.1 软件观测点
1. 主循环仍在跑，只是业务路径没反应
2. 中断未到或链路未更新
3. 发生了阻塞式等待或超时问题
4. 上层工具接错端口或被错误进程抢占
优先关注以下函数与状态：
### 9.3 历史上已经确认过的典型软件问题
1. `BootDiag_ReportCh390()`
2. `ch390_runtime_probe_identity()`
3. `ch390_runtime_init()`
4. `ch390_runtime_poll()`
5. `ch390_runtime_check_link()`
6. `ch390_runtime_input()`
7. `ch390_runtime_output()`
以下问题在历史排查中已经出现过，应优先复核，不要重复踩坑：
### 6.2 硬件观测点
1. PHY 访问无超时，导致永久卡死
2. 刷新未初始化的 IWDG 句柄导致 HardFault
3. 在长耗时 SPI 路径中错误扩大临界区，导致看似“系统假死”
4. 在多个层次同时触达 CH390 / SPI，导致运行时边界混乱
5. 配置口命令结束方式不对，导致误判为 parser 无响应
优先关注 CH390 芯片脚侧：
---
1. `RSTB`
2. `SCS`
3. `SCK`
4. `SDI/MOSI`
5. `SDO/MISO`
6. `INT`
7. `VDDK`
8. `AVDD33/VDDIO`
9. `AVDD33`
10. `XI/XO`
## 7. 常见误区
## 10. 常见误区
调试当前工程时，应避免以下误区：
1. 不要再直接沿用“CH390 恒为全 `0xFF`”这一过时结论
1. 不要继续沿用“CH390 恒为全 `0xFF`”这一过时结论
2. 不要在 `main.c`、IRQ、netif 多处重新插入原始 CH390 访问
3. 不要在没有芯片脚侧证据前，只凭 MCU 侧 GPIO 就认定 `RST/CS/SCK/MISO` 正常
4. 不要在基础寄存器读写尚不可信时，直接调高层 `TCP/UART` 业务逻辑
5. 不要把一次性的 bring-up 实验代码长期留在正式启动路径中
6. 不要让 `VOFA`、`ncat`、自写 Python 服务端等多个进程同时监听 `8081`；否则板子可能连接到错误的本机进程，导致 RTT 显示 `connected` 但目标工具无数据
3. 不要在没有芯片脚侧证据前，只凭 MCU 侧 GPIO 判断总线正常
4. 不要在基础寄存器读写尚不可信时，直接调高层 `TCP/UART/MUX` 业务逻辑
5. 不要把一次性 bring-up 实验代码长期留在正式路径中
6. 不要让多个本机进程同时监听板子要连接的 TCP 端口
7. 不要在尚未证明命令已真正进入 parser 之前，直接归因到 Flash、协议或网络层
## 8. 当前推荐结论表达方式

## 12. 当前推荐的结论表达方式
若需要向项目成员同步当前状态，建议采用以下口径：
1. 当前工程软件架构已稳定在 `bare-metal + lwIP RAW + ch390_runtime 单一拥有者`
2. 当前 CH390D 已恢复基础寄存器读写，调试重点已转入初始化完整性、链路、中断与收发功能
3. 硬件验证仍必须以 CH390 芯片脚侧波形与电源域量测为准
4. 上层 `TCP/UART` 联调应建立在 CH390 初始化、链路与供电稳定三者都可信之后
5. 本项目已确认过一次真实硬件根因：CH390D 供电滤波电容虚焊会直接表现为网络收发异常
2. 当前调试重点已经从“CH390 是否完全无响应”转移到协议、链路和系统级联调
3. 当前对外协议和配置模型应以 `MUX / NET / LINK[idx]` 为准
4. `USART1` 配置口、`USART2/3` 数据口与 TCP 路由必须按最新代码路径调试，不应再参照历史 `IP/MASK/GW/PORT/RIP/RPORT` 公开接口模型
5. 硬件验证仍必须以 CH390 芯片脚侧波形和供电域量测为准
