- **SS:P2_6** = 2 * 32 + 6 = 70  →  16进制就是 `0x46`

- **INT:P3_17** = 3 * 32 + 17 = 113  →  16进制就是 `0x71`

- **RST:P1_15** = 1 * 32 + 15 = 47  →  16进制就是 `0x2F`
## 3. 板子rework
根据板子原理图可知R59 R60要接在2-3的位置

> 发生异常中断

### 解决办法
1. 调整 TCP/IP 线程栈大小
   - 配置项：`RT_LWIP_TCPTHREAD_STACKSIZE  4096`
   
2. 重新编译并烧录

3. 联网正常，`ping` 百度可通
