* 收发缓冲区 —— 全局静态，不在任务栈上。

|
||
* s_tx_buf 仅在 Phase 8(大文件) 和 Phase 10(边界) 中使用。
|
||
* Phase 7(TCP Client) 使用函数内局部小缓冲（64B 递增 + 回显）。
|
||
*
|
||
* 大小依据：
|
||
* - CH395F 单 Socket 接收缓冲按 1KB block 配置（net_socket.c 中
|
||
* set_recv_buf(sock, 30, 2) = 2KB），单次 net_recv 至多返回 ~2KB，
|
||
* 故 s_rx_buf 实际只需 ≥ 2KB（此处 32KB 留足余量）。
|
||
* - Phase 8(大文件) 现改为流式分块：每次仅填一个窗口（≤1024B）即发出，
|
||
* 不再一次性填入整文件，故 s_tx_buf 只需 ≥ 单窗口大小（此处 32KB 留足余量）。
|
||
* 取 32KB(32768) 同时满足两者并留余量，且为 2 的幂；相比原 64KB
|
||
* 在 STM32F4（128KB RAM）上节省一半静态空间。

* Phase 8 — 大文件 / 批量传输（默认 100KB，文件收发）
|
||
*
|
||
* 测试目的：验证超过 Socket 接收缓冲（2KB）的大块数据在 net_send /
|
||
* net_recv 层经分块后的正确处理；并支持「文件发送(MCU→PC) /
|
||
* 文件接收(PC→MCU) / 回显 round-trip」三种方向。
|
||
*
|
||
* 数据模式：递增字节，绝对位置 p 处字节 = (p & 0xFF)；发送端按窗口
|
||
* (offset + i) 生成，接收端按 offset 逐字节比对（自校验）。
|
||
* 整包另用 CRC32（与 PC zlib.crc32 一致）做整体校验。
|
||
*
|
||
* 缓冲策略：s_tx_buf / s_rx_buf 仅 32KB，100KB 须按窗口逐块生成/校验，
|
||
* 不整体驻留 RAM（流式分块）。
|
||
*
|
||
* 方向选择（编译宏 PHASE8_DIRECTION）：
|
||
* 0 = ECHO 发 100KB 经 PC 回显，MCU 收齐校验（默认）
|
||
* 1 = SEND MCU 发 100KB，PC 落盘 rx_100k.bin 校验
|
||
* 2 = RECV PC 发 100KB（+4B CRC32 尾），MCU 收齐字节+CRC 校验

* 测试目的：验证 CH395F 的 TCP KeepAlive 机制：
|
||
* 1. 连接空闲超过 idle 阈值（60s）后开始发送探测包
|
||
* 2. 探测无响应（默认 3 次 × 5s = 15s）后触发 TIMEOUT
|
||
* 3. Socket 自动关闭并回到 LISTEN
|
||
*
|
||
* 入口条件：Socket 0 处于 ESTABLISHED，PC 连接后静置（不发数据）。
|
||
* 通过：KeepAlive 断开时间 ≥ 60s（从连接建立到 recv 返回 0 的间隔）。
|
||
* 失败：不到 60s 就断开（可能是其他原因导致）或 75s 后仍未断开。
